Karcher K2 Pressure Washer Review: Overview and Features

The Karcher K2 pressure washer is a 1400W machine with a 4m hose and a flow rate of 360 litres per hour.  It has a telescopic handle and wheels to enhance mobility.

This makes it easy for you to move between different cleaning jobs. The on-board storage is a great addition as it enables you to conveniently store the hose, Dirtblaster, electric cable, and gun.

The pressure washer can be used for cleaning cars, garages, patios, bicycles, furniture, and much more. It has a spray wand that is easy to adjust and can tackle different cleaning jobs no matter how challenging they may be.

The unit is light and compact and you can easily move it as you go about your cleaning.   It is not noisy at all. It’s not a hassle setting the machine up and putting it away as it is easy to move around.

To help you draw detergent from a container, the pressure washer has a suction tube. But in order to effectively do that, ensure that the machine has been set at the lowest mix pressure.

The machine has an automatic start/stop motor to prevent water from flowing continuously when washing.   It will instead switch itself on/off when necessary.

The motor has a built-in air cooling system that helps to supply fresh air to the motor when the machine is in use. When the motor stays cool, the machine will have a longer lifespan. The pressure washer has a built-in inlet that prevents the entry of debris and damage to the pump.

Karcher K2 Accessories

Vario Lance

The goal of the Vario Lance is to achieve different pressure controls. By twisting the lance, you can choose from four different settings.  These are:

  • Soft – This setting is indicated as a good option for washing a fence.
  • Medium – This is the best option for washing a car
  • Hard – This setting  is suitable for surfaces, brick and paving items
  • Mix – This is for mixing detergent when using a little pipe

I didn’t find any major difference between the Soft and Medium settings. For example, you can use the soft or medium setting and you will find it effective in washing cars.

Home Kit For Patio Cleaning

The Karcher K2 pressure washer comes with a home kit (T150 and Detergent) that makes it quick and efficient to clean a wide range of exterior surfaces.

The formula ensures efficiency in cleaning your home. The T150 patio cleaner enables you to clean large surfaces such as decking or patio without any splashing. The deck detergent helps to get rid of stains.


The Dirtblaster is a rotary nozzle that has been designed with rotating pencil jets and can provide more efficiency when compared to a standard high-pressure lance. This makes it effective in getting rid of stubborn dirt.

You should avoid using this option when washing a car or any other surface with soft paint. I prefer it best when I use the gentle stirring motion instead of the up to down or left to right.

High-Pressure Hose

The 4M hose can be easily connected to the main pump and jet. This makes it an ideal length to clean your car. You should take note that the high-pressure hose moves from the machine to a spray gun.

You will need to get a hose pipe that moves from the water butt or garden tap to connect the unit’s input. This has to be bought separately as an accessory.

Karcher K2 Pressure Washer Review: Final Thoughts

Kärcher K2 Full Control Home Pressure Washer

There are many reasons why I liked the Karcher K2 pressure washer. It can save you a lot of time cleaning and therefore, make life easier for you. It is easy to apply the detergent using the suction tube.

The onboard storage makes it easier to carry and store. The T150 patio cleaner is a good choice for cleaning large areas of decking, patio, car, garden or block paving.

The addon for cleaning the patio is a really helpful feature especially if you want to remove dirt and prevent water from spraying all over the place. The Dirtblaster is a good option for removing those stubborn stains.

The pressure washer has full control lances with a picture to guide the user in the right pressure setting. With all these features, you can see why I recommend this pressure washer. This is a very helpful washer that you can use for the majority of domestic cleaning jobs.

Whether you need something to wash your car or clean your drive, you don’t have to buy a more expensive model as this one will handle most tasks efficiently. Karcher offers a 2 years warranty which is a good thing when you want to be sure of your investment.
