Karcher K5 Full Control Home Pressure Washer Review

Our Rating

Quick Summary: Karcher has some of the best pressure washers on the market and the K5 range are the more sophisticated models. The Karcher K5 Full Control version in particular is such a quality pressure washer that’s packed with plenty of features which make it very convenient in use. For information, it’s an upgrade from the Karcher K5 Compact Home Pressure Washer. It maintains the yellow and black colour scheme, however, the body has been significantly improved. This model is ideal for all types of domestic cleaning and we are going to uncover its capabilities below.


  • Designed with on-board storage for keeping the trigger gun, 2 lances and hose neatly stored together on the unit.
  • Has a convenient extendable pulling handle and wheels, which make it easy to manoeuvre within the job area, whether you’re washing the patio, car, deck, and more.
  • Comes with a powerful motor – 2100 watts – which features a patented cooling system for increased longevity.
  • Features LED display on power gun which allows you to ensure that you’ve selected the right power level for a particular application.
  • Comes with quite a substantial hose of 8m length, making it ideal for washing large areas.
  • Includes a T350 patio cleaner and a 1L bottle of 3-in-1 stone and facade cleaner.
  • Uses Karcher’s Plug and Clean Detergent system which makes for quick replacement of detergent with one simple movement.
  • 3 year warranty


  • A bit expensive than most alternative pressure washers.

Specifications and Features

  • Maximum pressure bar – 145 bar
  • Maximum flow rate – 500l/hr
  • Area cleaned in square metres per hour – 40
  • High pressure hose length – 8 metres
  • Motor type – water cooled
  • Detergent application method – Plug and Clean system
  • Includes high impact wheels and adjustable aluminium handle
  • Dimensions: 397 x 305 x 584

From the figures above, you can tell that the Karcher K5 Full Control Home Pressure Washer is a fantastic device. This pressure washer will handle the job of a smaller pressure better and quicker. After all, you don’t want to spend a full hour washing the driveway when it can be done in half an hour.

Powerful water cooled 2100w motor

The major advantage of the K5 Full Control pressure washer over smaller models is that it integrates a water-cooled motor instead of an air-cooled motor. Delivering an unbelievable 2100 watts of power, this motor offers a superior benefit of longevity compared to an air-cooled motor type.

LED display trigger to selection correct pressure setting

One amazing feature of this pressure washer is the LED display on the power gun. The LED display basically shows you the power output you’re using for the job and will always let you select the convenient programmed setting to suit the job at hand. The pressure washer runs on 2 AAA batteries which are included.

The ability to store your accessories on the body, such as gun, lances and hose is another major benefit offered by the K5 Full Control pressure washer. In addition, you can simply store everything on the pressure washer and then pull it into the shed or garage using the extendable handle.

What’s more? This pressure washer comes with two lances which utilise Karcher’s patented lance technology for increased efficiency. The first one is the Vario Lance which can vary the spray from fine to high pressure jet via a simple twist of the lance. The other one is the Dirtblaster, which is handy for blasting away stubborn dirt from weather worn surfaces. So whether you want to ‘soft wash’ your car or get rid of mud on the driveway, the K5 Full Control will up to the task.

Includes T350 T Racer Surface Cleaner which cleans much faster

Changing the accessories is in itself an easy process thanks to Karcher’s Quick Connect system - forget about unscrewing rigid joints and cursing the machine.Also supplied with the pressure washer include an 8m high pressure hose, T350 T Racer Surface Cleaner and 1 stone detergent.

The T350 T accessory makes cleaning various exterior surfaces quick and spray free. It also has a handle for reaching up on vertical surfaces like walls and garage doors. On the other hand, the stone and façade cleaner with 3-in-1 formula cleans and cares for stone patios, walls and facades around the home. The instruction manual will show you how to fix the detergent bottle onto the machine but its simply just clicks into place.

Another thing we like about Karcher is that they fully stand behind their products. For instance, the K5 Full Control pressure washer comes with a huge 3-year warranty, which is superior to many of Karcher’s competitors. In addition, Karcher’s authorised dealers are all over the UK so in case of any urgent repair, you can visit the nearest shop rather than shipping your issue via the mail.

Final Conclusion

The Karcher K5 Full Control Home Pressure Washer is a heavy duty machine that would make most outdoor washing jobs a breeze. It beats most other pressure washers in its class in several aspects including power output, flow rate and bar pressure.

While the K5 Full Control unit might be expensive for some, the benefits cannot be overlooked. These include faster completion of tasks, flexible operation and enhanced durability of its water-cooled motor. Every domestic user will find the machine very easy to use and store away.

With that said, it’s hard to point out any faults of this pressure washer. Perhaps the price is the only drawback.

We would highly recommend this product on the basis of quality and performance. Go for it if you can afford it but if your having second thoughts the Compact K5 is cheaper but just lacks a few fancy features but still has the 3 year warranty.

Karcher K5 Compact Pressure Washer 145 Bar New 2019 Model 240v

Our Rating

Karcher introduced the K5 range into the market earlier this year and the response so far is amazing. Among them was the Karcher K5 Compact Home High Pressure Washer which has become very popular with homeowners. We’ve done our best research and below we tell you why this pressure washer is one of the best on the market.

Quick Summary: The Karcher K5 Compact is an excellent choice for those looking for a powerful but compact pressure washer that is easy to store and has great mobility. We actually prefer the K5 Compact over the K5 Full Control Pressure Washer despite it lacking the LED trigger gun and detergent 'plug n clean' system. If you need a model that can be store easily, is powerful and can easily be moved around then this model ticks all the boxes and comes with 3 years warranty. 

Let’s start with the summary of the good? and bad.


  • Very powerful 1800w water cooled motor that produces 145 bar.
  • Compact design making it easy to store and transport.
  • Has a water-cooled motor which tends to last longer and its quitter than air-cooled motors.
  • Designed for easy manoeuvrability and transportation due to its compact body with two carrying handles.
  • Allows easy attaching of the lance and high pressure hose via Quick Connect connection device.
  • Can source water from tanks and water butts and filter it to eliminate large particles.
  • Has an Auto Stop function which helps save electricity by stopping operations every time the trigger is released.
  • Offers on-board tool storage for gun and lances.
  • 3 years warranty for full peace of mind.


  • Uses a detergent suction tube you need to insert into a container. Would be more convenient with the plug n clean system or on-board tank.

Specifications and Features

  • Maximum power output – 2100 watts
  • Flow rate – 500 litres/hour
  • Maximum pressure – 145 bar
  • Area cleaned (m²/h) - 40
  • Weight: 11.5kg
  • Includes detergent suction hose for detergent injection
  • Made with a telescopic handle for easy use and storage
  • Dimensions: 516 x 295 x 282mm
Light weight and easy to store thanks to its compact design

As the title suggests, the Karcher K5 Compact Home High Pressure Washer really stands out due to its ‘compact design’. This machine can be carried to and from the job area using two integrated carry handles. At 11.5kg (without accessories), a large majority of the physically fit population will find it easy to lift, whilst others can find it easy lifting it side by side. Still, it’s fitted with two large wheels which enhance mobility. The dimensions of the pressure washer are 46.8 x 39.7 x 59.1cm and they make for easy storage.

Water cooled motor increases the life span

It benefits from a water-cooled motor that leads a longer life compared to an air-cooled motor due to tougher tolerances. A water-cooled motor runs quietly and is the kind installed in high grade pressure washers.

Quick connect hose connectors for easy setup in minutes

Featuring a Quick Connect system, the pressure washer allows easy connection of the high-pressure hose as well as other accessories. As a matter of fact, the hose has a decent 8m length which is more than 6ft longer than the K4 which helps cover wide areas in less time.

The Karcher K5 Compact Home pressure washer comes with two types of lances; the vario lance and dirtblaster lance. The former allows you to change the power of the water stream from soft to high pressure jet, whilst the latter provides a rotating water jet for maximum cleaning capability.

Includes the T350 patio cleaner which cleans patios 5 times faster than a lance

Another included accessory is the T350 patio cleaner, which precisely does what its title implies but its also great for cleaning walls and garage doors thanks to the handles fitted to it. The box also contains 1L wood and stone detergent (3-in-1 formula) that cleans and leaves surfaces shiny.

An impressive feature of the K5 Compact Home machine is its filtered suction capability. This allows filtering of all incoming water to remove large particles that may clog the hose and cause damage. In addition, there’s an Auto Stop feature which basically halts operations whenever the trigger is released. The pressure washer will resume operations once the trigger is pushed again. This functionality will help enhance the durability of the motor which means it will last longer.

With this machine, you can expect to wash an area of up to 40 square metres in an hour as determined by its bar pressure and flow rate. Karcher know they have an outstanding product and they are confident enough to cover this pressure washer with a 3-year warranty. Some other brands will give a maximum of two years, so Karcher sets the bar in the market.

Final Conclusion

This is a great kit for various washing jobs at home. Anyone looking for a compact pressure washer with plenty of power will find joy in the Karcher K5 Compact Home High Pressure Washer.

There’s so much to celebrate in this product, including a patented water-cooled motor, quick connect system, ease of use and on-board storage. With this pressure washer, you’ll save a lot of time cleaning the patio and driveway, and get better results than using a less powerful model.

Even more, it’s fairly priced when you consider what it comes with, the washer power it offers and the longer 3 year warranty.

Now this model is around £100 cheaper than the Karcher K5 Full Control Pressure Washer and produces the same results, the only real different is that it does not have a LED trigger so you can see the pressure setting you have it on and it uses a detergent suction tube instead of the plug n clean system which we do love but it not essential.

Personally would invest in the compact version and same the extra money to buy some usefull attachments which are available.

That being said, the more expensive K5 model is just as good and has some interesting features which, if within budget, are worth investing in.

All you need to decide is whether you would prefer to splash out the extra expense on the extra features of the Full Control model such as the 'Plug n Clean' detergent system and the LED Trigger so you know instantly what pressure setting you have. Or do you prefer the compact lay-flat design, better mobility and the more attractive price.

Once you decide this you should have your answer to which Karcher K5 model is the best choice for you.
