Excellent high pressure cleaning for all your needs! Whether you are cleaning your car, patio or decking the K399M does a great job. I've transformed my car from a dirty embarrassment into a clean gleaming mean machine. The long hose means it’s easy to get round and clean all the corners of even the largest car with no problems.

The wheel base makes it easy to maneuver this robust and durable pressure washer around. I found this especially handy when cleaning large patio areas. The high pressure enables you to get rid of the toughest marks left from those autumn leaves and annoying weeds and moss growing in the cracks.

I also found using the Kärcher 2.640-212 T-Racer Patio Cleaning Pressure Washer Accessory, with futuristic hovercraft action and powered by its rotary jets, gets even better results for patios and decking alike.

This high quality washer is great value for money and stores away neatly in my garage. - Joe McArdle, Amazon.co.uk

    Ok while it works1
    I brought one of these in August 2007 and have used it about ten times before it sprung a leak - spurting water through the vent.

    This was to replace an older Karcher 630 washer which went the same way - and looking at reviews elsehwere clearly a Karcher feature!

    Karcher seem dis-interest offering to sell me a re-engineered model to replace it - probably one of the many returned???

    Nilfisk do a 2 year warranty (C120 being similar to the K3), Karcher just a year.

    Karcher appears to work on their reputation aa the products seem to have a life just passing the warranty period so you buy more. I would suggest you look carefully at other makers before going for a Karcher

    As experienced by other reviewers, this item leaked badly after v. little use. Suggest buyers look elsewhere.

    Good reasonably basic pressure washer. Great for the motorbike, not bad on paths, fences, walls etc. Good value.
