Karcher K4 Compact Pressure Washer 240V is rated 4.3 out of 5 by 7.
Rated 5 out of 5 by from Excellent washer Excellent pressure washer, only criticism need better storage for hose.

Rated 2 out of 5 by from Poor, especially with static water source Bought to replace K2 which expired after only 2 years. The K4 worked great first time, but totally dead next time. After conversation with Toolstation & Karcher, got advice that it was likely airlocked and how to clear this. However, they seem to think it’s ok that this is a frequent happening, especially when used with static source not mains pressure. As that mode of operation is advertised as a feature of K4, this is not good enough.

Rated 5 out of 5 by from Cracking machine. This pressure washer replaces a much cheaper one I purchased some time ago. I have to say that this machine is very impressive. Powerful enough to get my tatty driveway looking great..

Rated 4 out of 5 by from Does what it says Just cleaned our very grubby paving with the dirt buster wand. Really does work but will probably now need to repoint joints.

Rated 4 out of 5 by from Cleans boats too I bought the K4 without extra tools to clean off the hull of my 27ft fibre glass boat when it came Out of the water for the winter The assembly was very straight forward although I have not figured out how to take the high pressure hose out of either the machine nor the lance handle for storage. It did the job well at full power it even cleared away small barnacles and sliced through mud and weed. It even reduced the ingrained stains at the water line I had to mask off neighbouring boats and a building with a plastic tarp because of the reflected fine mist spray. I could see that the adjustable twist power feature would be very convenient for patios etc
