For the price, even if it had only lasted through the first time I used it, I would have bought another one for the next time! (I used on a 100'+ concrete driveway and my neighbor borrowed it as well, it's still in good order.) It cut my time by more than 1/2 over using a wand easily. Saved me a sore neck from looking down also LoL

I have only used this once on our sidewalks but found it much easier and efficient to use than a simple power wash nozzle. A slight downward pressure on the wand is required to keep the head in contact with the surface, but a slightly longer wand should make that easier. The brush-like surround really contains the spray and I found much less disruption to surrounding areas and it also kept me drier. A good homeowner tool for sure!

We had bought another brand prior to buying the Karcher; the difference was significant. The Karcher had actual bearings on the rotating shaft, was well balanced and spun freely when spun by hand. Even our lower powered electric pressure wassure was able to perform quite nicely without leaving the swirly concentric circles when moving at a reasonable pace. On our Simpson 3200 PSI pressure washer it worked like a dream.

I have a gas powered machine. This worked fantastic! It usually takes me days to clean my 3 gray composite decks. I did it in four hours. It was easy to connect and using it was as easy as vacuuming a rug. The only possible negative feature is, if it spins around too much as your moving it, it could unscrew off the base. So you just have to watch for that.

Finally got time to use this new gadget Love it. Last time my 4 car driveway took entire day with simple pressure washer. With this, 2 hours. Very satisfied. I now see the issue folks are complaining about the nut. Yes you have to tighten it repeatedly but its not a show stopper. Would totally recommend.

Needed to pressure wash driveway. In the past it took most of the day, moving the wand back and forth, over and over. With the Karcher pressure washer attachment, my time was cut at least by 75% and the results were more even. In a lot of reviews people wondered why they didn't buy this years ago. And me to that group!

Cut my time to a third vs only the wand.

Worked OK with my 3000 psi pressure washer from Costco. Be aware the Jets put out enough thrust to cause the cleaner to get airborne. Downward pressure on the handle is definitely required to keep it on the ground. The recommendation by another reviewer of adding a 2 foot extension wand might assist in the controllability. When pressure washing around my pool, I found it very easy to blow debris and dirt into the pool. When washing a narrow area, you may find it better to just use the jet wand. I did. We'll see how long it lasts. The rotor inside the plastic head is made of metal so hopefully it will be durable.

I found this surface cleaner to jump more than others I've used in the past. Mostly the Briggs

Surface cleaner worked great the first day, did a nice job on my deck. When I went to use it the next weekend, I could not get it to work right. It would start to run then lose power, pulsing high and low pressure. I cleaned the spray nozzles, hooked up to a different water source, no improvement. When I changed back to a regular nozzle the pressure was fine. I do not think it is the surface cleaner but an interaction with my 2650 PSI pressure washer. Have not had time to trouble shoot it yet.
