What we don’t like about the Kärcher K4 full control Pressure Washer

Despite the price tag associated with Karcher products, this one has a cheaper feel to the main body.

We of course don’t get to review product over a year, usually only over a day but it has been reported that over time, the O-rings wear and leaks from the main body start to cause problems with the running of the Karcher k4.
