Well worth the price.

Edwin February 20, 2026

I had borrowed my neighbors power washer. He had a 11 inch service cleaner. I was amazed how good it did on my driveway and pool pavers so I returned it to him and purchased the 12 inch service cleaner attachment for him. He stated he wanted the 12 inch but his wife bought him the smaller one. He came over yesterday and said a big difference the 12 inch attachment did. Differently would give the 10 stars for the price and ease of using.

I did not expect this

Raymond BAKER November 13, 2025

When I opened the box of this 12" surface cleaner, I thought no way. It was very lite and not much to it. I figured I'll give it a try; I had thing to lose. OMG I Couldn't believe it. It worked great it cut the time of power washing my driveway by more than half. No streaks and easy to handle.

False advertisement

anonymous October 20, 2025

Same your money or be prepared to order several extensions! It leaves streaks of dirt, have to go over the same small spot 3 times and still wasn't clean, it removed very little dirt. FYI I was useing it on my pool deck so there wasn't much dirt to begin with

Greenworks surface cleaner

tjjmdean May 15, 2026

The greenworks surface cleaner works great. I wasn't sure if it would fit my Snow Joe pressure washer, but it did! I have a 30 x 60 patio and driveway. This attachment will make cleaning easier and faster.

power washer attachment

Katey June 9, 2026

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.

Works really well

Hamertime June 26, 2022

This is the first time in a long time I have purchased something that works just as described. The rotating surface cleaner took a tedious job (power washing the driveway) and cut the time by at least 75%. Is there a learning curve, yes but once you master the device, it takes minutes and not hours to complete the task. We were even able to use it on our painted brick retaining wall and it did an excellent job. I just wish I had purchased one sooner.

Greenworks 12" Surface Cleaner

JWilloz September 24, 2021

After reading all the less than good reviews about most surface cleaners, I finally tried Greenwork's 12 inch circular surface cleaner on my concrete porch. I was really surprised how well it worked. Nothing I had used in the past could completely clean the grim, mold and algae buildup without using bleach on our rough concrete porch. Our new GW's 3000 PSI pressure washer had just the right amount of power needed to do the job. We are very pleased with the results and best of all my back is not hurting this morning as I did not have to manually scrub the rough-concrete nor did I have to use bleach. JW

I got this for my son for his summer pressure washing job. We were impressed with the job it did for the cost.

12” Rotating Surface Cleaner

Justsayen711 August 18, 2025

[This review was collected as part of a promotion.] Saves time. Cleans a larger area than using just the hose especially on larger areas.
