KARCHER PRESSURE WASHER REVIEWS

 Kärcher K5 Compact Home High Pressure Washer with Home Kit Review

OUR BEST PICK

Kärcher K5 Compact Home High Pressure Washer with Home Kit Review


Kärcher K5 Compact Home High Pressure Washer with Home Kit

The Kärcher K5 Compact Home High Pressure Washer with it's Home Kit is another heavy duty unit and the winner of our top recommended karcher pressure washer. The 2100 watt high grade water cooled motor operates at a maximum pressure level of 145 bar which is high enough to clean even in the most demanding situation but compact enough to be easily stored at home. The approximated water flow rate is at about 500l/h which is one if the best water flow rated we have seen from a pressure washer, specially one for home domestic use. Since the motor runs to provide higher output, it needs to be cooled by water in order to elongate user life so is good to see that karcher have opted for the water cooled motor for this model rather then the cheaper air cooled motor you often see.

To aid in controlling the pressure, a hand trigger has the option to switch to different pressures depending on the job at hand, this is an excellent feature that is very useful as it can be lowered to prevent damage to more delicate jobs thanks to the quick connect ends, again a big improvement to the usually screw ends you see on most models. The trigger also facilitates the easy attachment and detachments of the two different lances that come with this model. Another feature that has easy attachment is the hose mechanism. The fast attachment mechanism is a time saver due to its simplicity and also prevents the worry of the usually screw type attachments that can be easily damaged.

The unit weights an estimated 11.5kgs but this is without the attachments so add a couple of kg's for the the true weight. All though its not to heavy for most people it comes with large wheels which make move it around much easier, specially for those who may struggle otherwise. Together with the adjustable handle, the user can now move the unit without pulling a muscle. The handles are padded to avoid harming the user’s hands and to provide enough grip. All in all a great design making it very mobile.

It comes with an long 8 meter cable which is longer then the K2 and K4  but not quiet as long at the hose fitted to the K7. However we fell that 8 meters is more than enough even for those larger driveways and patio areas. To ensure that the hose doesn’t let particles through, the unit is also fitted with a filter which helps prevent damage to the pump.

The set we reviewed which is the Home Kit is supplied with a vario lance, a dirtbuster lance, Stone and Façade 3 in 1 Cleaner, a 3/4inch hose adapter and a T 350 Surface Cleaner which is perfect for speeding up cleaning patio and drives as it cleans it up to 5 times faster, it even has a handle so you can use it to clean walls and garage doors. All these features can be used in different instances thus providing value for money specially when you  consider it comes with a 3 year warranty. One last feature which we think is great which we nearly forgot to mention, it can be used in the upright position or lay down, this is something the K5 Full Control Pressure Washer cannot do.

  • exclamation-triangle
    Lacks compartment for storing the lance, therefore, giving the user more tasks to find adequate storage. A simple solution is to hand it on a hook or nail fastened to the wall.

Final Conclusion

The Kärcher K5 Compact Home High Pressure Washer is made for those who need more power than the average user and is a great alternative to the Karcher K4 as it has more power and a longer hose.

This unit that operates at a pressure level of 145 bar will effectively handle cleaning walls, vehicles and walk ways without any real problems.

Our main grapple with this unit is the lack of compartments to effectively store things. One has to think about storage options for the hose. Apart from that, it is a reliable unit.The surface cleaner has well-constructed and durable handles to help you clean that patio squeaky clean and we like that it can be used on walls as not all patio cleaners have handles to make this possible.

Overall this model is offers performance, quality and value for money which helped it win the spot for our top recommended Karcher pressure washer. After comparing the cheaper K4, we decided it was worth spending the extra cost to get the longer hose and extra power the K5 provides.

 Kärcher K2 Home Air-Cooled Pressure Washer Review

Kärcher K2 Home Air-Cooled Pressure Washer Review

Kärcher K2 Home Air-Cooled Pressure Washer

The Kärcher K2 Home Air-Cooled Pressure Washer is easy to use due to its lightweight construction and Karcher's most affordable pressure washer. The unit is equipped with a 1400 watt motor that runs efficiently to produce 110 pressure bar which is only 20 bar less than the more expensive K4 models. The air cooled washer is adequate for cleaning small patios and drives, small cars, bicycles and any other general cleaning applications.

This model comes with a vario lance which has a bayonet style end on the lance, simply twist the end to alter the pressure from low pressure to high pressure. A simple but very effective way to control the pressure.

This model comes designed to produce water flow of 360l/h. This compared to larger models may seem inadequate. But due to the size and design of this product, the water flow is adequate to accomplish cleaning small tasks making it ideal and affordable for anyone looking for a light weight model for smaller cleaning jobs like cleaning bikes off or even a small car.

If you have stubborn stain that has been glaring at you for a while, you need a model that offers detergent applications. The Kärcher K2 Home Air-Cooled Pressure Washer lets the user suction preferred detergent into the unit without any problems making it convenient for all. The only real downside is that it does not have a built in detergent tank, this can become a problem if you need to constantly move the pressure washer around as you have to also move the bottle of detergent at the same time which can be awkward.

Easy manoeuvrability even in rough terrain is possible. The unit is equipped with durable wheels and a handle so that the user can pull it along. A storage compartment is present in order to store the cable and other essentials you may need them but they feel a little cramped but do the job.

To add more value for money, this product is presented with a few accessories that could be useful to you. You will find a vario lance which we have all ready mentioned that will enable water pressure control from low to high or vice versa. A dirt blaster is also provided to help you deal with stubborn areas. The dirt blaster utilises a rotating nozzle increase pressure used in dislodging dirt. Last but not least we have a T150 Patio Cleaner to help with cleaning applications on the patio.

A 4 meter hose is supplied in order to provide you with adequate reach when cleaning in a small radias. Also, you will find that this product comes with a 2 year warranty that can be used in the case of any product flaws but its proved very reliable when not over worked so this should not be needed for the majority of us.

Final Conclusion

The Kärcher K2 Home Air-Cooled Pressure Washer is effective for those small cleaning applications where you don'y need meters of hose length and very high pressure. It has a 1400 watt motor that runs efficiently, but if it is overworked, you will have issues. 

For the price, this units features are more adequate and it offers great value for money. If you are looking for a lightweight unit that can take care of simple cleaning applications such as cleaning your car once a week, rinsing off the bikes or even cleaning a small patio a few times a year, then this is the one for you.

The main downside of this model is the hose length, if you have a larger car such as a 4x4 then you will struggle as the hose length is not quiet long enough. If this something you are looking to clean then we would recommend getting the next model up, the K4 which we review next as it offers the extra hose and slightly more power. If your cleaning off your bikes or garden chairs, this will do just find and is more than adequate.

 Kärcher K4 Full Control Home Pressure Washer Review

Kärcher K4 Full Control Home Pressure Washer Review

Kärcher K4 Full Control Home Pressure Washer

The Kärcher K4 Full Control Home Pressure Washer can effectively deal with even the most demanding cleaning tasks but at the most affordable price, still its more that double the cost of the K2 so read on to see what the extra money pays for. We feel there a big improvement between the K2 and the K4 in terms of extra features, more power, better more reliable motor, longer hose for better reach, better storage, better detergent cleaner application, the list goes on.

The 240 volt motor is water cooled to facilitate overall high performance, this is where a lot of the extra cost goes, water cooled motors cost much more than air cooled motors. A motor that runs hot for too long stands to be damaged by all that heat and needs an outlet, this is why air cooled motors cannot be used for long periods of time. A water cooled motor will run for much long due to continuous heat management, simply put they are much better.

Pressure washers come with different pressure ratings. The more pressure produced the easier cleaning will be. This unit comes with a pressure rating of 130 bar which is more than adequate to cover 30m2/h effectively, to give you a batter idea the K2 has an area cleaned rating of 20m2/h, which is a third less cleaning time.

When it comes to water flow rate you cannot ignore this spec as it gives a good indication of how well it cleans. The higher the rate of water flow the more intensive the cleaning process will be. This unit is designed to house a water flow rate of 420l/h which is more than adequate for medium applications.

The trigger is fitted with an LED indicator which shows the current power level setting so you know whether the pressure is set to low or high which at the very least helps avoid you pressure washing fragile surfaces on full power and avoids unnecessary damage. As you have adjustable pressure settings from high, low to detergent, the trigger will indicate which pressure you are working at, its not a major deciding factor but a nice feature to have.

Another nice feature is the on board storage, this is of course a feature of all models but nevertheless, this helps keeps everything neat and tidy when store away.

Some models are fitted with suction mechanisms in order to dispense detergent. This model offers the option of the in-house detergent compartment. Just plug the detergent unit in and you are good to go. At first we though this would be expensive if you had to replace karcher own plug in detergent bottles, however you can be refills so could refill with what ever detergent to choose.

Also to help with the cleaning, various accessories have been provided. You have a vario lance and a lance blaster in order to deal with the difficult areas which we have all ready discussed. You also get a T350 T-Racer surface cleaner with a handle for easy use, again this is one of the better surface cleaners as it can also be used on walls and doors ect thanks to the handle design. This pressure washer is supplied with a 3-in-1 detergent that can tackle most of the dirt around your home so your good to go out of the box.

For reach, this unit is supplied with a 6 meter hose. This is longer than the previous K2 model, therefore, you won’t have to struggle as such with larger cars and patiosn. When it’s time to call it a day, you can pack up the components of the units, store them in their respective compartments and wheel it away. The durable wheels on this unit paired with the telescopic handle, which is also much better than the K2  fixed style handle, make mobility and storage a breeze. You also get a 2 year warranty that you can engage the manufacturer on if any flaws are detected. Remember, this is a years less warranty than the K5 which is our best pick, in our mind we think that this means that Karcher expect the K5 model to last longer but we have no proof of this.

Final Conclusion

The Kärcher K4 Full Control Home Pressure Washer is a step higher than the normal pressure washer. The water cooled model is designed in such a way that every feature well placed to provide a compact unit. Considering that the unit weighs around 11kgs it was only prudent that wheels and an ergonomic telescopic handle are installed and it feels well balanced and stable.

We love that the trigger offers and indicator to inform the user what function they are operating at, again not essential and certainly does not improve performance, but a nice added feature.

Overall, you can rely on this unit for proper cleaning functions aided by the accessories provided. It will cost you a little more coin than normal but it is worth the sacrifice and a big improvement on the K2 alternative. If the K5 is to expensive and not within budget this is a great alternative model to choose without going for the budget model which may not be suitable for your cleaning jobs. All in all, we love the K4 and think it is a fantastic pressure washer, its just the K5 obviously has the edge.

 Kärcher K4 Compact Pressure Washer Review

Kärcher K4 Compact Pressure Washer Review

Kärcher K4 Compact Pressure Washer

The Kärcher K4 Compact Pressure Washer is another high performance unit that is reliable, its a more compact version of the Karcher K4 we have justed looked at with a few small differences, one being it can be used lay down. Powered by an 1800 watt watered cooled motor for optimum performance, the motor is equipped with an automatic trigger that lets you chose when to render the motor active, this means it only runs when in use which reduces general wear.

This quality pressure washer is a breeze to move from one place to another. This is due to the long lasting wheels and telescopic handle. Seeing that it weighs around 11kgs the wheels balance the weight of the unit when being pulled making it easy to move around.

For maximum cleaning, you need adequate pressure. A pressure bar of 130 is adequate to deal with medium cleaning applications which is basically those around the average garden. When it comes to water flow rate this unit can accommodate a maximum of 420l/h. Paired with the 130 bar pressure, this pressure washer is perfect for applications such as cars and bicycle washing among many others. The unit is also fitted a filter to prevent any debris from the water messing with the pump which can damage the pump.

Some of the pressure washer models have weak connection systems between the hose and the unit, this is specially true for weak screw type connectors. This model comes correct by introducing an easy to secure and reliable hose connection. The quick connect saves the user time that could have been used screwing the hose on. Just the K4 full control pressure washer it also comes with a 6 meter hose will provide you with all the cleaning reach that you need.

Detergent enabling mechanisms cannot be overlooked since sometimes you need to remove tough stains. For this washer, it employs the suction tube method. This basically lets the washer get detergent from an outside source such as a bottle of detergent. We think this is where this model could be improved at our best pick has the click and go type detergent tank where you simply insert a bottle into the machine. However the simple suction tube way is adequate.

Accessories provided to help with cleaning include a lance and a dirt blaster with a nozzle that rotates. This seems to be an industry standard and they are seemingly convenient when you need more pressure.

To ensure that the unit is compatible with the garden horse, the Karcher group has provided a 3/4 adapter that you can use to connect the water.

Finally you get a 3-year warranty which is just a sign of good faith in the product presented.

Final Conclusion

The Kärcher K4 Compact Pressure Washer is a great alturnative to the Karcher K4 Full control pressure washer and is slightly cheaper without some of the fancy features which include the LED control the more expensive model has but is not essential.

What we love about this product is its compact fit and its easy hose attachment system as well as the power and build quality. We alsio like that it can be lay down which means it cannot be knocked over, a problem we have seen with the upright range of pressure washers.

The wheels and the telescopic handle are effective for transportation which makes it easy to balance the weight of the unit.

If you happen to be in search of a pressure washer that is water-cooled and has less fussy features, then this is the one for you. For a lighter unit that offers more or less the same function, look at the Kärcher K2 Home Air-Cooled Pressure Washer.

 Karcher K5 Full Control Home Pressure Washer Review

Karcher K5 Full Control Home Pressure Washer Review

Karcher K5 Full Control Home Pressure Washer

The Karcher K5 Full Control Home Pressure Washer runs on a 2100 watt water cooled motor just like the 'Compact Model' which won our top recommended model. This pressure washer can adequately cover 40m2 which is slightly larger than what other models can do with the exception of the K7 which we review next. This high performance unit is fitted with a pressurized trigger in order to control the unit. To notify the user on the mode of use, the washer is equipped with a LED indicator. You can tell what pressure you working with before rendering the unit active.

Handles on any kind of equipment need to be comfortable for the user to access. Short handles may cause the user to stoop which is not comfortable as we have found with the K2 which was not a major problem as its so light but this is not the case with this K5 model. The K5 pressure washer comes with an adjustable handle and wide wheels to offer weight balance. Without the wheels moving the 12kg unit would be a hustle for some people so this small but well designed handle is essential.

The unit is designed to hold all the parts in compartmentalised stations. Your vario lance, dirtbuster lance, trigger, power cord and hose all have a place to park. This, in turn, gives the whole unit a compact and organised form.

For those wondering what the working pressure is, here are the facts. This unit will operate optimally at a pressure of 145 bar and has a water flow rate of 500l/h. Since this unit has a higher capacity it can correspond to larger cleaning applications. The lances provided are adjustable so as to control the pressure.

The hose provided is also longer offering more meters. The longer the reach the easier it is to work without tumbling the washer over which we found to be a problem with the K2. Together with the 8 meter hose includes the extra 3-in-1 detergent, a T350 T Racer Surface Cleaner, vario lancer and a dirtbuster. The detergent can be plugged into the unit instead of the suction method which we prefer and think is a lot more convenient.

Final Conclusion

The Karcher K5 Full Control Home Pressure Washer will do perfectly for heavy cleaning applications and is a fantastic peace of kit, in fact it would have been our best recommended Karcher pressure washer had the compact K5 model not been cheaper.

In terms of cleaning performance and specification they are nearly identical but the compact model has the convenient features missing such as the plug in detergent instead of a suction pipe and the LED trigger. Again these are great additions but not essential which is why we decided to not choose this model as the best pick. Basically it came down to price which is an important factor to take into consideration.

Those who are looking for a top range pressure washer that looks good can purchase this unit and enjoy the extra convenience you get with this model. We found no major setback. We would consider this the best Karcher pressure washer for intensive cleaning applications that would be within budget of most people.

 Kärcher K7 Premium Full Control Plus Home Pressure Washer Review

Kärcher K7 Premium Full Control Plus Home Pressure Washer Review

Kärcher K7 Premium Full Control Plus Home Pressure Washer

The Kärcher K7 Premium Full Control Plus Home Pressure Washer is more than effective, to say the least and is probably the best pressure washer available for home domestic use but it comes at a price but you get a lot more pressure washer for your money, bigger motor, more cleaning power, longer hose, integrated hose reel, not to mention the plug in detergent system, LED trigger and 5 year warranty.

It weighs a hefty 17.7kg without the accessories which is a lot more than the K5, this shows you how much power you can expect from the unit. The 2800 watt motor operates at a maximum pressure of 160 bars, again 15 bar more than the K5, proving to be powerful enough to clean driveways. With an 600l/h flow capacity cleaning has never been this easy.

Most pressure washers come designed to house two lances. This pressure wash does you a big favour. It combines the operations of the dirtbuster, detergent function and the vario lance all into one unit. The all improved lance has controls that allow the user to select the right settings. The LCD display situated on the trigger gun to help you control the unit as you continue working.

In the spirit of easy detergent replacement, this unit features a simple structure. You invert the detergent so that it can directly feed the washer. This works better than the suction pipe method. Considering that you have a 10 meter hose you can scrub that driveway spotless covering an average of 60m2/h.

Since it is a hefty motor, there is a need for wheels and a handle. The good thing is that the handle is telescopic simular to that we seen on the K5. This indicates that it can be adjusted to suit the user’s needs. The handle is ergonomically designed to provide grip even when the user has sweaty hands. Grip and comfortability are supported.

When you need to connect the unit to your garden hose, a 3/4inch adapter is provided. A filter is also in the package to prevent unwanted debris from clogging the pump and causing the motor damage. Together with this, the package will include 1L 3-in-1 Stone/Facade cleaner, T450 Patio Cleaner and a home kit for use.

Storage facilities for cords are important since compact storage is guaranteed. This model is supplied with a cord reel to help you with this problem.

he 5-year warranty will aid in the case that problems arise with the unit.

Final Conclusion

The Kärcher K7 Premium Full Control Plus Home Pressure Washer is perfect for those who need a serious pressure washer for cleaning larger areas. The high pressure unit supplied with a high-pressure hose that can dislodge dirt very easily. We love that it is designed to house detergent applications and has a much longer 10 meter hose and integrated hose reel which is a big improvement on all the other models that simply have a hook to wind the hose round.

Those looking to spend money on a high quality and durable unit can't really go worng with the Karcher K7. Overall it is a heavy weight unit for a heavyweight cleaning and comes at a heavy weight price, however if you have the budget you will not be disappointment.

THE BUYERS GUIDE 

Searching for a good company to trust your washer needs may seem daunting. Fortunately for you, there are companies that excel in making pressure washers and Karcher is one of them.

To select the best unit for your use, you need to understand what the product specifications mean. Once you understand the features and what they have to offer selection will be very simple.

This is basically what you need to understand about pressure washers.

Type of pressure washer

  • mail-forward
    You will run into two types of pressure washers in the market. This categorisation is due to the two powers systems available. Electric pressure washers are light and easy to use without dispensing too much power. The only shortcoming is that with no electricity the unit is rendered useless. When using electric units, the higher the wattage the better as more power is provided for use.

    The petrol models are effective as they can be used anywhere. They are not limited by cords or heavy work. Petrol units can withstand everyday use without wearing down. They are a bit heavy than the electric models but very much efficient. They might cost more if they are units to be used for commercial reasons.

Size of the washer

  • mail-forward
    The size of the washer that you use affects the space taken up and the pressure that can be emitted. Light duty pressure washers operate below 100bar. Medium duty washers operate on pressure levels between 100-200 bar while larger models operate from 200+bar. Depending on how much cleaning you have to do, select the pressure accordingly. The higher the PSI the more you can dislodge difficult debris from your items and cars. Don't forget the higher the pressure the more expensive the pressure washer is likely to be.

Flow rate

  • mail-forward
    The water flow rate is measured in litres per hour. The more water that goes through the hose the faster you will be able to clean something. The higher the purported flow rate the better for you especially if you have a large area full of dirt to cover. Most regular units have a minimum flowrate of around 400l/h.

The detergent section

  • mail-forward
    Not all models come fitted with a detergent slot. This can be a hindrance when trying to clean using the detergent. You have two options you can select units that acquire detergents from outside sources or ones that use inbuilt systems. The suction systems can prove challenging if you keep having to move the pressure washer around. Most consumers prefer inbuilt systems that can move with the detergent holder even when the unit is in transit.

Hose length

  • mail-forward
    You need a high quality hose to keep up with the constant winding and unwinding. Poor hoses develop breaks along stress points. You want a hose with supple material to withstand stress. The longer the hose the more room you will have to work. We found that most people would need at least a 6 meter hose.

Additional accessories

  • mail-forward
    All proper washers provide excellent accessories to help the user with the cleaning process. These accessories will differ in use but are essential. In most cases, you find two forms of lances. The vario lance and the dirtbuster lance. You can even find a model that combines the two lances into one function. Other additional features are surface cleaners that help you clean without the need for so much water. The nozzles are designed at different degrees for different intensity so be sure to check the nozzle specification. We also have a variety of brushes and detergents being offered. Depending on what you need you can purchase a unit with the right accessories for you.

    Since all pressure washers offer different features and specialisation, they may vary in price. Basic units can be purchased under 100 Pounds. Larger units can cost over 500 pounds since they offer heavy duty service. Look at the work to be done, decide on a budget and try and stick to it. Remember to be keen on the quality of features rather than the quantity of accessories offered. We found a good pressure washer with attachments such as patio cleaners would cost between £200 and £300.

    Warranties are tools that manufacturers use to instil confidence in the product. Most washers offer warranties around 2 years but others can be extended. The thing to remember is that the longer the warranty the better for you. Most of the higher end karcher models have between 3 and 5 years warranty which big plug as some other manufactures on offer 2 years on similar models.

Adjustable and storage features

  • mail-forward
    In the case of washers, the only adjustable feature is the telescopic handle. In the case that the user is short or rather tall, they can adjust accordingly. Check the product description to make sure that an adjustable handle is present.

    On board, storage is important as it offers you a place to keep all the lances, triggers and hoses. There are models that offer compartments for every feature available therefore making storage an easy task. The K4, K5 and K7 have this covered but the hose hook on the K2 could be better designed.

Final Conclusion

It’s all a matter of preference when selection is concerned. There are many high quality products in the market and only the keen eyed can select the best.

Electric models are especially easy to find but be sure to keep a keen eye for quality. Pick products that offer you accessories and adequate storage features. This is just to make the product more useful to you. Other than that, remember the more power you need, the higher the product specification numbers should be.
