I received this as a gift - it was supposed to be compatible with my littel electric Sun Joe SPX200E power washer. It took me a little while to find the right adapter to make the end of the SunJOe wand fir the 1/4" connections, but it is available. Finally got to try it out today - it really exceeded my expectations. Moving the surface head along about a foot per second left the concrete fully clean. The thing is quiet, and my washer doesn't generate huge pressure, so I was really impressed by how such a wide swath was cleaned so quickly. I'm looking forward to using it on other surfaces, especially the swim deck on our dock.
Wish I would have bought this the last time I sealed my driveway. It did a great job and didn't leave streaks in the concrete like a wand does. After each section, I did have to use the wand with a 40 degree bit to rinse dirt and cleaner off the concrete. Even with doing that, it saved time.
This is my second surface cleaner I use for home and small jobs for family, it works very well for what it was designed for! Will be purchasing a third for a gift!
This model is so much sturdier than a previous brand I used to own. I really like using this surface cleaner on just about everything, from concrete sidewalks and driveway, to area rugs and tarps, and even the flagstone patio pavers. It even deep cleans the lower brick sides of our house, and the patio doors where the dog scratches up the glass.
