    Rated 5 out of 5 by from Karcher K4 I've had a couple of the smaller karcher pressure washers before but decided on a bit of an upgrade this time - not disappointed, a lot more control for different materials etc and seems better on the car as well!

    Rated 1 out of 5 by from Extremely unreliable I received a second unit as replacement for the failed first. The second unit had operated for less than a day before pumping out water from underneath and pressure fluctuations. The retailer is refunding and refusing to handle the product again.

    Rated 2 out of 5 by from Item is not the one in the video as advertised The video tells you about the "hose guidance system" the K4 does not has this. The hose just coils up on the back of the machine. I bought this washer because its tidy to store away with the hose that retracts away only to find out it doesn't. Dissapointed. I may have well bought the cheaper model and saved over £60.
