K4 Premium Home is rated 4.0 out of 5 by 4.
Rated 2 out of 5 by from Good product - when it works... I've had the K4 for 13 months - although strictly speaking this is the second - had problems with the first one within 2 months when the on/off switch stopped working. Took it back to shop who replaced it with a new one. 11 months later, the same problem with the replacement - luckily it was still under the 24 month guarantee, so had it fixed at local Karcher centre, though as they were unable to find a problem with the switch, did locate a problem elsewhere, but informed me that it would not have affected the on control - so hoping it keeps working...

Rated 4 out of 5 by from good all rounder Great all rounder, but the cable and hoses are a bit cumbersome, easy to get tangled. If the base was a bit longer it would be easier to wash the car without having to constantly move the pressure washer. This is the only reason I didn't give 5 stars.
