Product Details

Don’t be fooled by its small size, because this latest generation Karcher K4 Compact pressure washer certainly isn’t short on power. Extra water flow and pressure combine to give you an impressive performance that gets the job done faster.

A state-of-the-art, water-cooled 1800W motor gives outstanding performance, and an integrated suction tube allows detergent to be applied to any surface being cleaned. The long-life motor gives outstanding durability too.

Two lances are included, which you can switch between depending on the job. Choose the VarioPower lance for cleaning delicate surfaces such as paintwork or a car, or go for the Dirtblaster lance when you need some extra power on harder surfaces like stone and brickwork.

Karcher K4 Compact Pressure Washer 130 bar is rated 4.6 out of 5 by 242.
Rated 5 out of 5 by from Amazing pressure washer I have been wanting to upgrade my pressure washer the compact K4 for a while. The discounted price from toolsatation was too good to miss. A great pressure washer, easy to store with its compact size. Very powerful with an adjustable lance - Low pressure, then medium mist before moving into very high flat jet. I definitely recommend this product from Toolstation.

Rated 5 out of 5 by from Handy size with great power I have used this to do a few jobs now and it is a very handy size compared to old K5 machine. Power is fine. One thing I did find is that pressure hose is shorter than on old machine but as it is light to move around then easy to do work.

Rated 4 out of 5 by from K 4 Compact Does what it says good little product but have to agree with the other reviews about the storage picture and reality. It does not wrap round neatly like shown but not a problem. Its still compact and does not take up much room in the garage

Rated 5 out of 5 by from Great compact pressure washer I bought this product at the end of December to replace an old one that had burnt out. The pressure this produces is fantastic. It is small enough for me to store in my small shed.

Rated 5 out of 5 by from K4 Power washer Only used it twice since I purchased it. Once for paving stones and second time to wash our two cars. Great washer really powerful and being able to adjust the pressure to suit both jobs.
