K 4 Compact is rated 4.3 out of 5 by 26.
Rated 4 out of 5 by from K4 Compact customer review. Brought this model for it size, storage and power capacity. Have used upright power washers and found them bulky, tend to fall over when over extending washer hose. K4 Compact ticks the box for me. It was not easy to buy locally, Argos had the best price but only one in stock. Brought extras such as Patio cleaner T-350 from Wickes, 360 Vario jet from Homebase, all at discounted prices.

Rated 3 out of 5 by from Motor housing seals an issue Though had the machine for around 3 years and not really used it that often. The motor housing seal or seals been replaced 2 times. Water leaks from bottom seal. Seem like the rubber seal/or plastic motor housing could be improved.

Rated 5 out of 5 by from Cracking machine..... I bought this about a month ago , it’s my first pressure washer although I have used Kärcher steam cleaners at work for years now.. It’s probably fair to say that it has exceeded my expectations. Just one thing I would like to add, although it states in the operators instructions that you must ensure that the water is flowing through the machine before the power is turned on, please do as I nearly made the mistake of not doing this as my hosepipe is fitted with a ‘Hozelock Aqua stop’ fitting which seals when an attachment isn’t fitted and I found that I had to give the fitting an extra push onto the washer after it had clicked into place. If unsure I would recommend doing as I did , unscrew the Kärcher fitting from the washer and clip it into your hosepipe fitting and ensure water flows through it when the water supply is turned on.... I have also experimented with a ‘snow foam gun’ attachment with great results..
