8 Best Cordless Pressure Washers

Regarding pressure washers in general, I’ve always had electric pressure washers connected to the mains tap, which included my Karcher K2 and, more recently, the Karcher K5 with smart control. At my family’s garden centre, we’ve always used petrol pressure washers, so when these cordless pressure washers first caught my attention a few years back, I was very doubtful and wrote them off as more of a gimmick than a useful cleaning tool.

Fast forward a few years and some testing with the Worx Hydroshot shown above, and it’s a different story. It definitely won’t be replacing my Karcher K5 pressure washer pictured below, but cordless pressure washers can definitely be a fantastic tool. It all really depends on your situation and your plan to use a cordless portable pressure washer, but once you own one, you find so many uses for them.

Karcher K5 compared to other models
Cordless pressure washers still lack the power of electric models, but they still have the uses.

To give you an idea, my Karcher K2 above, which is one of the smaller electric pressure washers and a very popular model, has a ‘bar’ rating for pressure of 110 bar; my Karcher K5 also show above has a pressure rating of 145 bar. Now, the WORX 20V MAX Cordless Hydroshot Portable Pressure Washer, probably the most popular portable pressure washer, has a pressure rating of only 22 bar. That is a big difference!

Even the extremely expensive Makita DHW080ZK Twin 18v Li-ion LXT Brushless Pressure Washer pictured abovee, which I would also describe as a professional tool, only has a pressure bar rating of 55 bar. I’m trying to point out that you won’t get the same cleaning power as a corded electric pressure washer. I don’t want your expectations to be too high!

However, they definitely have their uses and are very good for particular jobs. For starters, if you don’t have access to a water faucet or plug socket anywhere (although the plug socket part can be overcome with a portable generator), then using a good battery powered pressure washer is going to be your only option. It’s also a good option for anyone living in an apartment or flat who might not have the storage space or access to power or water to use an electric pressure washer.

Cleaning off mower with cordless pressure washer

They have proven brilliant for washing bikes down after a ride out, especially before loading them back into the car or onto a trailer. I personally also do a lot of kayaking in my ITIWIT 100 Touring Inflatable Kayak in the summer, and it’s proven perfect for washing down and cleaning off any sand or mud before letting it dry and packing it away. Basically, any time you could do rinsing something down but need a little power, it could be a dirt bike, cleaning off your mower deck, washing a boat, a 4×4 off-roader, cleaning portable BBQ, dirty patio furniture, or simply cleaning your own car; a portable pressure washer is a perfect solution and more than up to the job if you buy a suitable model.

What they are not good enough for is cleaning heavily soiled patios or paths; for this, I would suggest using a patio cleaner such as Smartseal 5L Patio Clean Xtreme that you apply and rinse off if you can’t use a more powerful mains-powered pressure washer or petrol.

Before I get into my detailed reviews of each model, I want to briefly mention a few of what I think are the best cordless pressure washers currently available. Firstly, I don’t think most people can go wrong with the WORX HYDROSHOT Pressure Cleaners; however, there are a few different models, but there is not a great deal of difference between them.

I recommend the WORX WG620E model, which is rated at 22 bar. The main issue, as with most cordless models, is run time; at 25 minutes, it’s long enough to clean a small car, but you may need to consider spare batteries or choosing a set that comes with a bigger battery, 4Ah instead of 2Ah for example. WORX also makes a version with a brushless motor called the WORX WG630E, but even this model only has 24 bar of pressure, so there is little difference in power. However, it does recharge in 1 hour instead of 4 to 5 hours. It also has a bottle adapter, which means you can attach a 2-litre soda bottle filled with water to the pressure washer. It may also come with a larger 4Ah battery instead of the 2Ah standard, unless you buy the bare tool.

I like that it comes with everything you need: a pressure washer, lance, battery, and charger; some offers even include a few more accessories, such as brushes. It’s worth noting you can put the suction tube into a bucket of water or even draw it from a river, lake or pond; this can be useful for some people. You can still attach it to your outdoor tap, which is also useful.

Ryobi 18V ONE+ Cordless 22bar Power Washer cleaning concrete patio

Now, if you already have other Ryobi tools, such as the cordless chainsaw or drill like I do, the 18v batteries and a charger will probably be compatible with the Ryobi pressure washer. In that case, investing in the Ryobi model, which gives the same performance and has a pressure rating of 22 bar, makes much more sense. It’s very similar, and then you only invest in the bare tool. Plus, being Ryobi, you know it is well designed and will be reliable, but at under £100, I think it’s a reasonable price. However, if you don’t already have other Ryobi tools. In that case, getting the Worx version probably makes more sense, as it offers better value for money with the battery and charger included.

Greenworks portable pressure washer

Now, if you’re looking for a cordless pressure washer that portable and totally self-contained and includes an integrated water bucket/tank, this Greenworks 40v Cordless Pressure Washer is by far the best choice for the price. Again, everything is included, and it also has the best pressure rating of all the pressure washers includes thee Makita DHW080ZK twin powered pressure washer. It has an impressive 70 bar of pressure. It also includes a large integrated 20-litre bucket that can be detached from the main unit and filled. You can remove the bucket and attach a standard mains hose pipe if needed as well. The run time is a little low at around 20 minutes, but it’s long enough for most jobs, and you can buy a separate battery if needed. Overall, it’s a fantastic piece of kit.

Makita DHW080ZK Twin 18V (36V) Li-ion LXT Brushless Pressure Washer
Makita DHW080ZK Twin 18V (36V) Li-ion LXT Brushless Pressure Washer

One other portable pressure washer that is the closest to an electric pressure washer in terms of performance is this Makita DHW080ZK Twin 18V (36V) Li-ion LXT Brushless Pressure Washer. It has an impressive 55 bar of pressure. Plus, being Makita, it’s well made, reliable and will tackle more demanding jobs, within reason!

Now, I still wouldn’t recommend it for cleaning large patios or replacing an electric or petrol pressure washer. However, for cleaning cars or small patios, it’s perfect. It also has a large 50-litre water container. The downside is that it is heavy; you are looking at 50kg when full of water, but it is on wheels, which definitely helps. The downside is the price; it’s insanely expensive!

Even if you already have Makita tools, compatible batteries, and a charger, it’s still very expensive and needs serious consideration. I would have a hard time justifying the cost myself; however, for someone looking for a professional option, it’s worth considering

8 Best Battery Powered Pressure Washer Reviews

1. WORX WG629E.1HYDROSHOT Pressure Cleaner

Buy on Amazon.co.uk

My WORX WG629E.1 HYDROSHOT Pressure Cleaner I've used for a few years

Pros

  • Simply insert the long 6 meter hose into any stationary water, such as a bucket or container.
  • Offers varied water pressure speed settings for removing different bulks of dirt.
  • Offers a powerful psi of 320 (22 bar) which is 3 – 4 times more than what a normal hose can offer.
  • Hydroshot possesses a rotating head at different angles to produce different water effects, such as mist.
  • Comes with a share-able battery that can be used by other WORX tools.
  • The battery charges up in just 3 hours giving around 20 minutes run time on full power and 30-35 minutes on low pressure.
  • Comes with a great set of accessories.
  • Offers a 3-year warranty for full peace of mind, just remember to register it online otherwise it comes with 2 years as standard.

This WORX WG629E.1 HYDROSHOT Pressure Washer is probably the best choice for most people. There is also now an upgraded version with a brushless motor and a larger 4Ah battery pack which provides power with 56 bar of pressure.

Now, the original version, with its smaller 20v 2Ah max battery, is still a great choice for most people and the one I review here. It’s perfect for cleaning cars, garden furniture, garden machinery, or anything where you need a little bit of pressure washer to really shift the dirt. This battery-powered model draws water from available sources and does not have a built-in water tank (like the Bosch, Makita and Greenworks models).

I recommend getting a water container to use as the tank, or of course, you could use a bucket of water but this may not be practical if you are travelling in a car. You can get a 25-litre water container for less than £10 delivered, or even a foldable version for saving space if this is an issue. 

My WORX WG629E.1 HYDROSHOT Pressure Cleaner adjustable nozzle

To effectively clean dirty surfaces, there needs to be a model that has a high psi, and this is where, for a portable model, the hydroshot really excels. This cordless water pressure washer is designed to offer a maximum psi of 320 or 22 bar. Depending on your water pressure, this could be ten times more water pressure than a standard garden hose or 3-4 times more powerful than a hose with a spray gun attached.

WORX WG620E.6 18V(20V MAX) Cordless 22 Bar Hydroshot Portable Pressure Washer with 2.0 Ah Battery, PowerShare, 120 L/H Compact Pressure Cleaner, Suitable for Patio Cleaning and Car Washing

You can adjust the water pressure to about 100psi. This is made possible through the variable speed settings that you can adjust at any given point simply by turning to adjust the spray.

A long lance is included to maximise pressure whilst also increasing space for control. Weighing in at a measly 0.59kgs, it is light enough to carry along and is probably one of the lightest models in my review.

WORX WG629E.1 HYDROSHOT Pressure Cleaner 20v lithium battery
WORX WG629E.1 HYDROSHOT Pressure Cleaner 20v lithium battery

All these functions are powered by a 20V lithium-ion battery pack that takes 3 hours to charge up. This gives you around 20 minutes of run time on full power and 30-35 minutes on low pressure so it might be worth investing in a second battery if the run time is a concern to you, that being said one battery will last long enough to rinse two small cars or one larger 4×4.

This set of batteries can also be used by other WORX 20V products, which may be useful if you already have, or intend to buy more power tools by Worx. You end up saving money over time.

Finally, it also includes a 3-year warranty if you register online within 30 days. It is important to note that the 30 days is from the date of purchase and not upon delivery, so if it takes a while to arrive, make sure you register it straight away.

Finally, it comes with a short lance, a carry bag, 6m hose, a soap bottle, a cleaning brush, a long lance, a foldable bucket, battery and a charger together with the unit and its nozzle.

2. Ryobi 18V ONE+ Cordless 22bar Power Washer (bare tool)

Buy on Amazon.co.uk

Ryobi RY18PW22A-0 18V ONE Cordless 22bar Power Washer (Bare Tool), 18 V

This Ryobi RY18PW22A-0 18V ONE+ Cordless 22bar Power Washer comes as the bare tool, so if you already own other Ryobi tools, this is probably a no-brainer at under 100 quid.

Because it’s a bare tool, it won’t have the required battery and charger. Just be aware of this. If you don’t already have other compatible Ryobi tools then it probably makes more sense to get the Worx version with the battery and charger included, especially if you go for the more powerful upgraded Niitro version with more power.

You can use the pressure washer for 30 minutes on a single charge on any of these batteries.

This pressure washer isn’t as powerful as some of the others in this review. It produces 22 bars of pressure compared to, for example, 50 bars of pressure with the Makita DHW080ZK Brushless Pressure Washer and 70 BAR for Greenworks version. However, this just means that the Ryobi model is better suited for lighter cleaning tasks and those items that don’t have dirt ingrained into them.

One nozzle lets you choose three spray patterns for the water. The turbo nozzle is for tough cleaning jobs, the 15 degrees fan spray is the workhorse spray for general cleaning, and the shower function is for rinsing. You also receive the siphoning hose that’s 6m long. This is for drawing water from a water tank into the pressure washer. 

And while you receive the siphoning hose, you don’t get a water tank. You’re on your own to provide a bucket, a rain barrel or something else as a container for the water the washer uses. Or you can connect the hose to a water faucet and draw the water from there in a continuous stream.

Pros

  • Power washer comes as the bare tool – without the battery and charger.
  • Three-in-one nozzle – fan spray, turbo nozzle and shower function.
  • Works for 30 minutes on a single battery charge.
  • Flow rate is 182L/hr.
  • Hose is 6m long.
  • Use with cold or hot water (temperature unspecified).

My recommendation

If you’re a Ryobi fan and have other power tools in their ONE+ family of tools, the Ryobi 18V ONE+ Cordless 22 bar Power Washer is a good choice for you as you won’t have to buy the battery and the charger separately. 

While not the most powerful cordless pressure washer on the market, this model is enough for most cleaning tasks around the home and garden. All your choices of water spray patterns are conveniently available on one spray gun. But you do have to provide your own water tank.


3. Makita DHW080ZK Twin 18V (36V) Li-ion LXT Brushless Pressure Washer

Buy on Amazon.co.uk

Makita DHW080ZK Twin 18V (36V) Li-ion LXT Brushless Pressure Washer
Makita DHW080ZK Twin 18V (36V) Li-ion LXT Brushless Pressure Washer

The Makita DHW080ZK Twin 18V (36V) Li-ion LXT Brushless Pressure Washer is definitely worth considering if you already own some Makita’s power tools with LXT batteries. This model is a “bare tool” in that it comes without the batteries (two 6.0Ah 18V batteries are needed) and the charger. Buying these separately significantly adds to the cost of the product. Even without the bare tool, it’s still very expensive, but it’s probably the best cordless pressure washer currently available from what I’ve seen.

The Makita DHW080ZK portable pressure washer has a self-priming function so you don’t have to worry about starting the water flowing through it. It comes with a very large storage tank on wheels into which everything fits when not in use. But empty out the tank and use it for holding the water, and you’re all set to go.

With the 50L tank capacity, you get to clean for quite a while before you run out of water. And the batteries last for 34 minutes when fully charged, so that’s another limit on how long you can stand there cleaning your car, dirt bikes, paths etc. But you can tell how much battery charge you have left by checking the LED lights on the battery casing.

Makita DHW080ZK Twin 18V (36V) Li-ion LXT Brushless Pressure Washer – Batteries and Charger Not Included

You also have the choice of three guns to release the water spray. There’s the trigger gun for a regular spray pattern, the jet lance for a more concentrated spray and the vario-spray lance. The last choice lets you move between the low pressure (30 bars) and the high pressure (55 bars) of water just by turning the nozzle. This is convenient when you’re cleaning something that has a variety of levels of dirt and grime.

You can use warm water up to a temperature of 40 degrees with this pressure washer. If you’d rather use water from a faucet (probably outdoors), it comes with a one touch tap connector (hozelock style). If you get your water this way, you can increase the pressure/speed of the washer up to a maximum of 80 bars for more power and oomph.

Portable 36v Makita pressure washer

When you’ve finished your cleaning task, let excess water out of the tank by using the tap at the bottom of the front side of the tank. Then wipe the tank down, put everything back in and wheel it (it has two wheels) away to your storage place.

Pros

  • Brushless water-resistant pressure washer with self-priming function.
  • Runs for 34 minutes with two 6.0Ah 18V Li-ion slide type batteries (not included).
  • Dual battery power gauge with LED lights.
  • Select either low or high pressure.
  • Water tank/storage tank capacity is 50L.
  • Includes trigger gun, variospray lance, and jet nozzle.
  • One touch tap connector to connect to the main water supply.
  • Maximum flow rate is 380L/hr.
  • Maximum water feed temperature is 40?C.
  • Has hook for shoulder belt attachment.
  • Hose is 5m long.

Cons

  • Batteries and charger not included.
  • Very expensive

My recommendation

This Makita DHW080ZK Twin 18V (36V) Li-ion LXT Brushless Pressure Washer is a good choice if you already have Makita power tools and have two 6Ah batteries and the charger sitting around at home. However, even without needing to buy the batteries, it’s still very expensive, so it will not be for everyone.

However, this is a good portable pressure washer to have if you need to rely on a water tank to hold the water you use. The 50L capacity storage case/water tank of this model lets you clean a significant number of dirty items in one session assuming you have the battery power. And the three different spray guns you receive let you choose the best spray for the task at hand.


4. Bosch Fontus Cordless Outdoor Cleaner

Buy on Amazon.co.uk

Bosch Home and Garden Cordless Outdoor Pressure Washer Fontus 18V (1 battery, 18 Volt System, in carton packaging)

Pros

  • Everything is truly self contained, water, battery even the brushes and models are stored on the pressure washer.
  • Comes with a large 15-litre water tank for seamless cleaning procedures.
  • Offers 4 spray patterns to attend to different cleaning functions.
  • It is a 15 bar washer pressure and therefore can handle small-medium sized cleaning jobs.
  • Features various water pressure speeds to tackle different kinds of cleaning.
  • Requires 18V lithium-ion batteries. These are compatible with other 18v Bosch products, which means if you already have Bosch tools, you can save money by just purchasing the bare tool without a battery and charger.
  • Comes with two cleaning attachments to cater to various cleaning functions.
  • Provides storage compartments for the hose and cleaning heads.
  • It has wheels and an extendable handle to facilitate easy manouverability.
  • Offers 60 minutes of running time and recharges in only 2 hours.

Are you looking for a pressure washer that has a bit more power, but a model that also holds the water and is 100% self-contained with everything you need all inside one unit? This Bosch Fontus Cordless Outdoor Cleaner is a great alternative to the Makita and much more affordable. You can use it to clean a number of things within and outside the house, including your dogs (on low), just don’t forget to set it to rinse before you hose them down! It runs on an 18v lithium-ion battery that is long-lasting and super energy efficient.

If you already have other 18v Bosch tools, you can even use the battery and charge from those tools and save some money just by buying the pressure washer as a bare tool, without the battery and charger. Taking up to 103 minutes, (that is just over an hour and 40 minutes to fully charge up) the batteries will then offer up to approximately 60 minutes of running time. Sixty minutes is adequate time to get a few things cleaned, so whether you are camping for the weekend and need to clean the bikes off in the evening or simply washing pram wheels off, I think it is more than long enough if you want to use it to clean your car.

To use the pressure washer, you need to fill the tank up first with 15 litres of water, yes it has a much bigger tank than any other model, so if a large water capacity is important to you, this scores high marks. These 15 litres can last a long period of time if you are only cleaning small items. If you are looking to undertake larger projects then you may need to refill the tank a few times, but with 15 litres of water, you could easily clean your car.

This model comes with two cleaning attachments, these include the nozzle and a cleaning brush. These attachments are designed to be removed or attached without too much effort. This, in turn, provides a seamless cleaning experience, even when you are trying to clean down your outdoor furniture. There is a compartment specifically designed to store the attachment when they are not in use which is a handy design feature. This will save you some headache when you are trying to store the pressure washer in a tight space and when you come to get it back out of the shed, you know where everything is.

This saves you some headache when you are trying to store the unit in a tight space.

The rotating nozzle head gives you access to different modes of water pressure. You can reduce or increase the water pressure depending on what you are cleaning. You can use the jet function to remove stubborn piles of dirt from surfaces or a soft spray to wash your dog. Also, you can choose the speed of the water being ejected between low, medium and turbo depending on what you are cleaning, so you really have ways to get the perfect pressure for the job you are undertaking.

To make moving the model easily, wheels were fitted into the design. The wheels are designed with treads so that they are able to manoeuvre the outdoor surfaces easily. The extendable handle is also well designed and makes matters even simpler as it provides a way to drag the machine along as you clean. The handle has been padded to ensure your hands are comfortable as it can weigh well over 15kg when fully filled with water.

What does stand out with this model is the length of the hose, it is much longer than most models and this gives you that little bit more freedom. The 4-meter hose (which is over 12ft long) is detachable and has a compartment that is used to store the hose when it is not in use. The battery pack and charger are both optional and are compatible with other 18v Bosch tools. This means that if you already have other 18v Bosch tools then they should fit the pressure washer and you could then invest in the pressure washer without the battery and charger and save yourself some money.

It is worthing that this model is not the most powerful on paper, the Worx Hydroshot, which we also review in this article, has more bar pressure but the difference is probably not too noticeable. Where the Bosch Fontis really stands out is that it has a large built-in 15-litre water tank and a lengthy 60 minutes running time and short recharge time. It also has a long hose (as we have previously mentioned) so you don’t need to move it around too much if you are washing down your patio for example.

5. Yard Force 22 Bar 20V Aquajet Cordless Pressure Washer with 2.5Ah Lithium-Ion Battery, Charger and Accessories

Buy on Amazon.co.uk

Yard Force 20V Aquajet Cordless Pressure Washer

This Yard Force 22Bar 20V Aquajet Cordless Pressure Washer comes with everything that you need to start your cleaning tasks and is a great alternative to the Worx version. Well, you probably need to charge the battery and definitely fill the collapsible water bucket, but that’s it.

As well as the battery and charger, it comes with a 3-in-1 cleaning wand. The nozzle of this wand has three adjustable sprays.  The jet spray gives you a wide fan shaped spray, the turbo spray puts out a high pressure spiral spray and the low pressure spray is for a lighter spray, used for easy cleaning tasks. You also get a brush for when you do need to scrub something clean and a soap dispenser for when you need to lather the object up, when cleaning your car for example.

As well as your choice of spray pattern, you choose from two speeds of water. The normal speed is the one you use the most for many cleaning tasks. But there’s also an Eco (economy) mode. Using this choice uses less water and less battery power. Your cleaning session lasts longer in this case.

The collapsible bucket that comes with this pressure washer looks rather small in the sales photos. No capacity volume is mentioned in the sales blurb. So you probably need to provide your own water tank for longer cleaning tasks or use water from a faucet for a continuous stream..

And the handle of the power washer adjusts to two positions for both your comfort and for ease of reaching into tight corners and nooks.

Pros

  • Portable compact pressure washer.
  • Includes 20V, 2.5Ah Lithium-ion battery and charger.
  • Battery has digital charging level indicator.
  • Two speed settings – normal and economy.
  • One nozzle with three adjustable sprays – jet, turbo and low.
  • Maximum 270L/hr flow rate.
  • Includes collapsible bucket for water (capacity unknown) and a storage bag.
  • Includes cleaning brush attachment and soap dispenser.
  • Handle angle is adjustable for comfort to two positions.
  • Hose length is 6m.

Cons

  • Provided water bucket looks quite small.

My recommendation

The Yard Force 22 Bar 20V Aquajet Cordless Pressure Washer with its 2.5Ah Lithium-Ion Battery, Charger and Accessories comes with everything that you need to complete a variety of different cleaning tasks. It’s basically a great affordable alternative to the Worx version.


6. Greenworks G40DC40 40v Cordless Pressure Washer

Buy on Amazon.co.uk

Greenworks portable pressure washer

Pros

  • Ideal for places where you need a pressure washer but don’t have access to water mains or power.
  • Offers a maximum water pressure of 70 bar to dislodge dirt from different surfaces.
  • Comes with a long 6 meter hose to give the user adequate reach, even when cleaning longer vehicles and caravans.
  • Uses a 40V lithuim-ion battery that is interchangeable with other Greenworks 40V products. (We recommend the 40v 4Ah battery for an increased run time).
  • It has a padded trigger handle for comfort.
  • Features a large 20-litre capacity tank to provide uninterrupted continuity of work.
  • Lightweight and easy to store with a good balance between power, practicality and affordability.

Clean anything, anywhere, using the Greenworks G40DC40 Cordless Pressure Washer that is designed to offer optimal performance and I think it provides the right balance between power and practicality.

The high-pressure washer uses a 40v lithium-ion battery to power the motor and its actually the most powerful pressure washer in my review. You can move from one corner of the property to the other, cleaning various surfaces without restriction, and it is fully self-contained with a built water bucket. You can also take it on the move as it is fairly compact, making it useful for cleaning off bikes before putting them back onto your bike rack, cleaning off gear after camping. Alternatively, it is also practical for cleaning cars and vans where you might not have direct outdoor access to electricity and water, for example, if you live in a flat.

Greenworks portable pressure washer being tested

If you already own other Greenworks products that use the 40V battery then you do not need to purchase another battery because the batteries within the group are interchangeable, this is becoming fairly commonplace for cordless tools. You will need to purchase a battery and a charger if you are not familiar with this brand as they are not supplied with the pressure washer.

This brings us to the run time. If you go for the smaller 40v 2Ah battery capacity, you will probably be disappointed with the run time. With this in mind, we recommend spending that bit extra and purchasing the larger 40v 4Ah battery and this should give you around 30 minutes running time from a single charge.

This pressure washer is equipped with a 20-litre tank, whether it is enough from a single fill will depend on what job you are doing. If you are cleaning a car, bikes and undertaking general clean downs it should be fine. If it is not, you could also carry a separate 20-litre tank to refill the pressure washer tank when needed.

With a water flow rate of 300l/h and 70 bar pressure, you can easily dislodge tough stains on different surfaces whether indoors or outdoors, but it’s important to not compare the power to a powerful electric model such as the karcher K5 as they are designed for different uses. But for most people, this should be plenty powerful enough.

It is not a particularly heavy model at 7.9kg, therefore, manoeuvering it around should not be an issue. The model is fitted with a handle to allow you to move it around without too much effort and the tank can be removed to make it even more compact for storage.

Finally, this model has a long 6-meter hose that provides adequate reach, permitting you to work freely and reach those tough corners. This is much better than most starter main pressure washers such as the Karcher K2 that usually have only 4 meters of hose. 

Greenworks portable pressure washer being used to clean decking

There is a jet nozzle supplied that releases water and has high pressure to clean different surfaces and the trigger handle is padded to provide cushioning as the user continuously grips it, which we think is a nice finish.

For those who are not near taps or electricity, you will be pleased to know that this pressure washer can use water from any source. Whether you are near a river or pond, you can fetch water easily using the bucket on the top section of the water. This feature allows for this pressure washer to be carried anywhere, whether for camping or cleaning the grill after a hearty barbecue. At the end of the day, you will find that this pressure washer will handle light-heavy work with unbeatable grace.

7. Kärcher 6v OC3 Portable Cleaner

Buy on Amazon.co.uk

Kärcher OC3 Portable Cleaner

Pros

  • Self-contained including water tank, lightweight and designed for mobility.
  • Comes with a 5 bar pressure rating that is low enough for gentler cleaning functions but provides enough power for jobs such as cleaning muddy bikes.
  • Perfect for hikers, cyclists, campers and other outdoor enthusiasts.
  • The water tank has a water level indicator to notify you when to refill.
  • Rechargeable built-in battery pack.

If you are always outdoors traversing the landscape, then the Kärcher OC3 Portable Cleaner is the model you need, to sum it up, it is small and compact so can easily be stored in the back of the car, has good pressure, probably slightly more than a hose and spray gun. However, the water capacity is smaller at only 4 litres which means it should last long enough to clean off bikes, pets, wellies for a few minutes. We would recommend perhaps carrying a collapsible water bottle to top it up if needed. 

The 2.17kg pressure washer is lightweight and is very well made, as you would expect coming from Karcher. This pressure washer comes in handy for campers, cyclists, hikers or those who work in muddy areas. Using a 6V lithium-ion battery will give you a running time of 15 to 20 minutes before requiring a recharge.

This is not a high powered model considering the amount of power it needs to run. Possessing a water pressure of 5 bars, you won’t be removing layers of dirt from your driveway, however, it is perfect for taking on the move, washing the dogs down and cleaning your bike etc.

It comes with a water tank that sits on top of the nozzle compartment and supplies cleaning water. The tank has a water-level indicator that reveals the amount of water left in the tank which is nice. As it is a low-pressure washer, you can easily wash your dog or remove mud from the driveway too.

The battery is not detachable from the unit like most models but it comes with its own battery indicator. The indicator will flash depending on the level of battery power left, this will remind you to recharge soon if you want to continue working. It is worth noting that you can get it with a car battery charger and many will find this option useful. It measures 27.7 x 23.4 x 20.1cm, therefore, storing or moving the model around will not be a problem and you can keep it in the back of your car if needed.

Overall, an excellent piece of kit if you just want to wash something down for a few minutes.

8. Sealey PW1712 Pressure Washer 12v Rechargeable

Buy on Amazon.co.uk

Sealey PW1712 12V Rechargeable 6.8kg Pressure Washer - 17ltr Water Tank

Pros

  • The unit is lightweight, weighing 6.8kgs.
  • Can be powered by a 12V external source or 12V rechargeable batteries.
  • Offers 40 minutes of running time.
  • Provides a 6m hose for easy manouverability.
  • Comes with two cleaning heads with soap bottles for seamless cleaning.
  • Provides on-board storage for accessories.
  • Features 8-bar pressure and a 17-litre tank to cater to various cleaning applications.

The Sealey PW1712 Pressure Washer is a lightweight model that you can purchase to help you with a number of cleaning applications and like the Bosch model, it comes with a large self-contained water tank that holds an impressive 17 litres of water. The downside to this is that it is heavy when fully filled and does not have wheels for easier mobility.  This is higher than any of the models featured in this review. 

With a maximum water pressure of 8 bars, this model is unable to handle large jobs but remember is not supposed to replace a mains powered pressure washer. This is a common mistake that some people make before purchasing it. It is important to consider what jobs you are using it for, cleaning your bike or car, yes it will do this brilliantly, cleaning moss off your drive, simply not powerful enough.

It comes with two cleaning heads so as to tackle different levels of dirt. The first is a spray head that can be rotated to adjust the water pressure whilst the second head is a cleaning brush that is great for cleaning your car. It is worth noting that both of these heads have been fitted with soap dispensers to make cleaning your car even easier, however, it is worth noting it won’t work with snow foam, but it is a really good feature to have as most models only use water and cannot be used with detergent.

Another valued feature with this pressure washer is the long 6-meter hose length, this gives you plenty of reach for cleaning larger cars. No matter the size of your vehicle, you can get around it easily and clean the surface effectively. It even comes with a shoulder strap to make transporting the pressure washer manageable but remember when it is fully filled with water this will be hard work.

Enjoy the onboard storage compartment that will hold the hose together with the cleaning attachments. This feature makes it simple to store and move with the unit whenever it is needed.

Finally, it relies on 12v lead-acid batteries, these are a little old school, the lithium-ion batteries are much better in terms of holding their charge and recharging quickly but the batteries on this model still do the job. That being said, it can also be powered by a vehicle’s 12V socket which is a handy feature. Depending on where you are, you can rely on either of these methods.

When fully charged, the pressure washer will give you approximately 40min of running time which is good. Overall, this model gets the job done and is much more affordable than our ‘best pick’, it is however just not in the same league in terms of quality, for the price though it is well worth considering.

Pressure Cleaner Buyer’s Guide

What do you consider when trying to pick between all the models to select the best cordless pressure washer on the market? Price is obviously a factor, but there are more important things to think about, such as portability and the ability for it to be self-contained.

What size of pressure washer is right for you?

Consider the amount of work that you want to undertake and the size of the model that you will be able to carry or push around. Larger models will provide you with a larger tank capacity and possibly more power to remove stubborn dirt from garden furniture with the help of the scrubbing brush.

Smaller models, such as the Kärcher OC3 Portable Cleaner will take care of smaller jobs like cleaning your bike after a day on the trails or a pair of dirty wellies. They also incorporate a much smaller water tank, to compare between models, the Karcher has a 4 litre tank while the Bosch has a much larger 15-litre tank, but it is obviously much bulkier.  Smaller models weigh less and have less sophisticated features compared to pressure washers like the Bosch Fontus Cordless Outdoor Cleaner.

Nozzle functions

It is important to have access to different nozzle spray functions so that you can clean different things. The nozzle pressure will differ when you want to comfortably wash your dog and when you need to get the mud out of your tyres. Models such as the Worx Hydroshot Pressure Cleaner come with different spray functions like jet and mist.

Soap bottles

Soap bottles save time, especially if you are in a hurry to get the car clean. Models that integrate built-in soap bottles are convenient as you can soap and rinse at the same time. Alternatively, if the pressure washer you want lacks one, you can always consider getting an independent soap bottle if one exists.

To give you an idea, the Worx pressure cleaner comes with a soap bottle attachment so you can wash things down with soap first. In the Bosch model, however, because the water tank is built into the unit, you cannot use detergent as it can damage the pressure washer, which means you can only use it to wash off mud with water pressure only.

Whether you need to use detergent would probably depend on what you are cleaning. If you are just rinsing your mountain bike down, probably not, cleaning furniture in spring after a winter outside, would probably be a good idea to use detergent.

Hose length and storage

If you don’t want to drag the pressure washer every few steps, search for a model that possesses a long hose. The Sealey PW1712 model comes with a 6ft hose but even with this length, you will probably still need to move the pressure cleaner around as you clean.

The quality of the hose matters as cheaper hoses will kink and often split, this is usually a problem with cheap Chinese imports and is just something to be aware of. Look for a hose that is flexible but still made of durable material. Many of the models being supplied on the market now feature some form of onboard cable storage too.

Additional accessories

We all like accessories that are delivered with our orders. It is like opening a double Christmas present. When you purchase your pressure washer, there are some things that you are likely to expect. These things include:

  • Cleaning brushes- these come in handy when you have a bit of scrubbing to do. These brushes are great at scrubbing wooden furniture or the steps to your house and of course bikes and cars.
  • Straps – not all models have this feature. However, it is possible to find mobile models that are designed to function with straps. These straps enable the user to hoist the pressure washer onto their shoulder and carry it around as you work.
  • Wash bucket – wash buckets are great for washes on the go. They easily fit into the car or a bag and you can move them from one area to another.
  • Tap adapters – for pressure washers that can be connected to running taps, some manufacturers are able to supply compatible adapters. This allows you to enjoy continuous cleaning action without the hassle of refills. This may seem like something not everyone who is looking for a portable pressure washer would need, however, it is always handy to at least have the option.

Wheels and handles

In the case that you are willing to put more money in, you can access the pressure washers that come with wheels and a handle. These two features make moving a slightly heavier pressure washer an easier task. You can glide with the unit behind you as you go about cleaning your surfaces. Both indoor and outdoor enthusiasts can enjoy the services of these pressure washers. An example of such a pressure washer would be the Bosch Fontus Cordless Outdoor Cleaner.

Warranty

To avoid wasting money on fake models on the market, we think it is safer to purchase a new model from a trusted brand or one that provides a warranty. The length of the warranty you need will depend solely on personal preference. It could be as long as 5 years or as short as 1 year, as long as the quality of the product can be vouched for. It’s worth noting that many manufacturers (including Bosch) offer a longer warranty when you register online so it’s well worth doing


Our Final Conclusion

There is nothing complicated about cordless pressure washers. They function the same way as their full-sized counterparts only on a smaller scale and they don’t quite have the same power but they do have the advantages of being much more portable.

If you need a simple model for simple cleaning applications then there is no need to shell out large sums of money. Invest in a model with adequate tanks and enough power to accomplish it. If you got heavy work to do, then I am afraid you will need to invest in a seriously powerful model and most cordless models probably won’t be up to the task. 

One last thing, we won’t dictate what should work for you because the best mobile pressure washer is a personal choice. Just think of what you need the pressure to do and whether you need a built-in water tank or whether you don’t mind carrying a separate water container.

If you own one of the models below then feel free to comment on what you think about the model and whether you would recommend it. We hope you have found our reviews helpful on the best cordless pressure cleaners.
