Greenworks Pro Universal 15-in up to 3100-PSI Rotating surface cleaner for Gas and electric pressure washers

I was surprised how fast it got the mold and mildew off my porch

Excellent results

Easy to set up, easy to use

It works well, but would be better with wheels.

I bought this so I could do our concrete surfaces, and it does a good jobs of cleaning. Though, you have to drag the item across the concrete. I expected it to somewhat “float” across the surface due to the force, but it did not. I ended up dragging it across the surface. Would have been better with small wheels built in.

Universal Fit - Clean Cement

Cleans beautifully with zero mess around cement edges

Must have unit for powerwasher

This rotating surface cleaner is amazing. It made powerwashing my patio driveway and all sidewalks so much easier. It also was stronger than using just the wand. I have an enormous patio and sidewalks in front and all around the house. It took me several days to get it all done and I would still be working on it if not for this add on - so easy to attach to powerwasher.

works great on flat or smooth surfaces. Does not work on uneven or salt finish surfaces, such as our driveway. Slightly disappointed, as our driveway is huge, but good job on the patios.
