What the experts say
Auto Express felt Karcher had compromised too much on power and lead length with the Karcher. It did result in a light, compact and downright cheap cleaner with some nice features but this was only enough to get it 3 stars.
Real Homes found the Karcher K" easy to set up (including changing heads) and to move around. However, the real problem lay in the power of the machine. It was fine for cleaning bikes and patio furniture but lacked the oomph to really deep clean a patio. It also uses a lot of water.
Good Housekeeping was more positive about the Karcher K2, scoring it well in its performance tests and finding it easy to use. They agreed it could clean patio furniture well but also thought it did a good job on patios if you use the "T-Racer" attachment (though this was less effective on decking. While the spray came out with too much force sometimes (which caused some splashback), the Karcher K2 did have to go over a car a couple of times to get it fully clean.
What users say
I already had a larger Kartcher which was dying a bit. This compact is a better machine IMO. Powerful and makes pressure washing easy. Recommend.
Karcher Patio Changer
Pressure washer arrived on time, and unpacked perhaps more compact than expected. But wow, washer works perfectly, removing layers of dirt and grime and leaving a lovely clean patio. Compact, easy to handle and powerful enough for my needs.
Karcher jet washer K2 compact
I brought this item for a Christmas Present and it was delivered when my husband was at home so yesterday used this lovely compact little machine. He thinks it is an exceptionally brilliant machine to use and does the job of cleaning paths and patio very well. It is not so heavy too so give it 5 stars. I also purchased the longer extension
Perfect for cleaning the patio and car.
I bought this item to replace my old power washer (not a Karcher). This item is much easier to use and is much more portable. It did the job perfectly and is much better to connect and use than my old washer.
Small and powerful
I bought this as my yard and patio blocks were desperate to be cleaned. It is superb. The yard was gleaming and the patio looks brand new, no need to even pull the weeds out, it blasted them away! Small enough to store away easily but powerful enough to do the toughest job
Compact but powerful pressure washer.
Looked at a number of reviews for this compact little pressure washer along with reviews for more expensive ones. Decided on this as small and had limited space for storing. Lives up to everything I read about it. Ideal for lots of jobs and gets them done fast.
Perfect for ladies like myself of a certain age. Easy to use.
Good compact verision
Used a jet washer for the first time on my very grubby patio. It was easy to use/move about. Did an above average job. However I found no difference between the two attachments - a standard attachment and then the Lance which was meant to have more of a kick it, so that was a let down with the more resistant marks; black spots on my patio. Finally, it is rather loud!! I felt pretty uncomfortable during the 4 hours of use because of the noise level, but I guess that is the nature of the beast.
