Karcher K4 Full Control review

Reviewed

Karcher introduced its 'Full Control' range of premium pressure washers in 2016. They are supposed to make it easier to choose the right strength of spray for your surfaces. The Karcher K4 Full Control is one of the cheaper models in the Full Control range. But is it as easy to use as claimed? We tested it on a range of dirty surfaces and cars to find out.
