Easy to use, great for cars

Bought it for washing cars and small house cleaning projects. Works great for cars, low enough pressure to not mess up the paint, but strong enough to get bug juice off the windscreen. Worked pretty good for my house siding (vinyl siding), and will use it on my deck when the weather gets a bit hotter. Easy to use, just need to make sure to bleed all the air out of the machine and hose before powering it on.

An excellent pressure washer

I bought this pressure washer a few weeks age. I am very pleased with the ease of use as well as the outstanding performance. It cleaned my concrete sidewalk and driveway beautifully. The instructions were clear.

Seems OK... with a few caveats

I bought this during the winter when it was on sale. It was replacing a lighter duty Kärcher model that gave me good service for about 15 years. A few days ago I was finally able to break this unit out for its inaugural run. It seems better built than my previous model, with more thoughtfully designed features and a few more attachments. Having said that, I was a little concerned during its operation. Several times, the electric motor seemed to change pitch, like the motor was starting to run away. I have this attached via a 3/4" hose with plenty of GPM and flow pressure. I'm not sure what the issue is, but it wasn't constant and was able to be rectified by cycling the power with the foot switch. And no, it had nothing to do with me depressing the trigger to run the unit. Additionally, the double female swivel filter included is pretty much useless junk. While my previous Kärcher power washer had a female inlet for the garden hose, this unit has a male inlet. Here in the US, outside spigots generally have a male thread, and garden hoses usually come with a male thread at one end and female at the other. By putting a male thread on the intake of the pressure washer, Kärcher is forcing purchasers to use a double female adapter at some point in the setup (or a garden hose with female fittings at both ends, which is uncommon). Fortunately, they supply an adapter with the unit. It also has a built-in debris screen to help stop any damaging particles from entering the pump. Unfortunately, the swivel provided seems to be of very low quality and leaks like a sieve. See attached photos. Your best bet is to replace the low quality included adapter with a commercially available brass double female garden hose swivel adapter. A filtering screened garden hose washer can also be added at any connection point.
