Greenworks 12" (in.) Surface Cleaner Pressure Washer Attachment

This works perfectly with my 1800 psi Ryobi pressure washer. It removes the dark gray grime on the surface of our 50 year old patio and leaves the terra cotta colored concrete underneath looking bright and new. Using our pressure washer without this attachment (even gently) damages the surface by removing some of the terra cotta coloring. This Greenworks attachment preserves the color, is gentle and super effective. It's easy to use and has our patio looking great! On one super smooth and almost shiny area of the concrete, it couldn't do much, but on the normal, rougher surface it worked very well.

Just used this for the first time today to power wash our concrete pool deck. In the past I just used the rotating tip on our power washer. It did a great job but took me most of the day. With this surface cleaner it did a better job and took substantially less time (about 2 hours versus 6 without this). I also used it on our fiberglass tables by the pool. They have a stone look and I could never get them completely clean with just the power washer tips. Using this they look good as new and took off years of dirt that were in the little crevices.

Cleaning my driveway and patio used to take forever with a regular pressure washer nozzle, so I decided to give this attachment a try. It made the job so much easier and did a fantastic job getting all the dirt off! A few helpful tips if you're thinking of getting one: you do have to move it pretty slowly—maybe just a few inches at a time. If you have areas that are heavily soiled or really stained, expect to make about three passes over the same spot to get it totally clean. Honestly, it would be even better if it had two extra nozzles on the inside for more coverage, but even as-is, it saves so much time and effort compared to using a basic wand. Overall, I'm really happy with it. It does a great job and takes way less toll on your body!

This was an absolute game changer. I have a GreenWorks power washer that I really like. I was dreading doing the pool decking. There is a lot of it and it takes forever using just the wand. I purchased this hoping to significantly cut down my time with this chore. I can’t express how well this attachment works! I did press ok with soap on the heavier soiled areas. Any darker areas required me to go over it a couple times. Each panel area used to take 20-30 minutes each depending on the size. This attachment makes it 5 minutes at most now. Easy to use. I did use the wand to trim on the outside of each area for detail work. Highly recommend it! Saves time and energy!

Great for the price! Just used it for the first time and it worked great. I would probably recommend one solid, heavy duty extension as it's a little wobbly and I'm scared it might break, but overall it works well. I have a small/cheap green works electric pressure washer and this attachment fit perfectly.

I easily connected this to my Greenworks 2000 PSI 1.2 GPM Pressure Washer. It requires no assembly and is easy to attach. I did find that it only liked to be pulled. I got resistance when I tried to push or sideswipe it. I have returned this because it does not clean as well as the 25-degree narrow fan tip nozzle. I went over my sidewalk with this and then again with the 25-degree nozzle and got off more dirt. I would say this worked maybe 85% of the way. If you've never power washed before and don't know what it could look like, I could see you being happy with this, or just settling for it since it's super easy, but it's not a 100% complete job.

I don’t normally write reviews but I felt I needed to with this one. This surface cleaner is incredible. It removed 20 years of caked on gunk from my driveway and patio without any difficulty at all. I would definitely recommend this product.

Easy to attach and get started. Feels a little flimsy, but for it’s totally fine for a home project. I used to clean my patio with just the hose attachment so this really sped up the process having an 11” diameter rather than 1”. Works great!

This surface cleaner did an amazing job on my composite deck. Easy to attach, and easy to use. Saves lots of time over pressure washing with just the wand.

Me parecio buen producto, si limpia, solo tienes que acostubrarte que no es una escoba, no puedes tallar fuerte como lo seria con esta.

Great product. merbau deck has come up great.
