Whether you're looking for a gentle touch to clean delicate paintwork on your car or you need a pressurised flow of water to remove stubborn dirt from a weathered wall, the K2 Compact is up to the task. The unit is not only compact, it's ergonomically designed meaning the handles fit comfortably in the hand. The K2 Compact is easy to carry and use - both during and in between cleaning jobs. The cables, hose and accessories can all be stored on the machine itself and the machine can be stored neatly in most cupboards or transported easily in the boot of a car. The K2 Compact jet washer comes with a trigger gun, a one way lance and a Dirt Blaster lance that can deliver 50% more cleaning power by using a concentrated rotating pencil jet. There’s also a 4m high pressure hose to give you plenty of reach and a detergent suction facility for lower pressure cleaning on surfaces such as car bodies. The plastic casing is impact-resistant and designed to prevent dirt from damaging the motor and pump, making the K2 Compact as durable as it is effective.

Pressure washer K2 Compact

K2 Compact is rated 4.4 out of 5 by 89.
Rated 5 out of 5 by from Does exactly what I wanted I have become very sceptical about 'gagets' that claim to be the answer to all my problems, so bought the cheapest version. I am delighted to say that on Sunday I cleaned my filthy drive, covered by moss, weeds, mud and the dirt of ages. The clearner worked perfectly, the power 'wand' lifted up all the moss and caked in mud, and the washer 'wand' helped move it off the drive into the drain. I ended up covered in mud and very wet, but that's possibly down to inexperience. The unit is light-weight and entirely moveable - I added an extension lead and had to ensure it was kept dry, but managed to reach every corner. Well done Karcher

Rated 5 out of 5 by from Unbelievable power for such a compact unit! I have owned a K'Archer pressure washer for near enough 25 years, which has given me years and years of service. I went to strip stain from our deck with it the other day and found it had neared the end of its life, which in fairness to it, was long overdue retirement. A friend of mine had just bought the K2 Professional and suggested I try it, so I had a go and couldn't believe how well it performed. Straight to Amazon and bought one for myself, although the compact, as I have many of the accessories already, which still fit the new models. I went back over my decking in 10% of the time it took me originally and what a difference! Well done guys on a superb, excellent value product. If it gives me half the service of my previous washer, I shall be more than delighted.....

Rated 5 out of 5 by from Great Machine. I bought this machine to replace an aging "Champion " washer. My first impressions were that the K2 is lighter than my ,old machine and more user friendly. I have used it clean my paving stones, steps and walls. I also used it to clean the tops from my gas hob.(Outside of course) All jobs completed with flying colors.

Rated 1 out of 5 by from Faulty Hose Thread This is my second karcher pressure washer. They don't last forever but I suppose what products do these days. I bought this one in May 2016 and the thread on the hose has worn out already August 2016. No I did not cross thread it before you ask. Apparently you are not supposed to take the hose on and off each time you use it? I did with my last one and it was always ok. I am currently waiting for a replacement hose to be sent through.
