Greenworks 11" Surface Cleaner Universal Pressure Washer Attachment

This really does a good job. Makes it faster and easier to power clean large areas. Highly recommend it.

I got this surface cleaner to use with my Greenworks 2700 PSI electric pressure washer. I wish I had gotten a surface cleaner years ago! I tried it on a concrete driveway, a couple of concrete pads that had some serious moss growth, a redwood deck, and a natural stone walkway. Greenworks isn't exaggerating when they say the surface cleaner is five times faster than a regular spray tip. It is not only much faster, but it resulted in a much more even cleaning than using a spray tip. It would remove minor moss growth if I went over the area more than once, and even removed ~1/2" thick moss if I gave it enough time, but I found a better approach was to use the turbo nozzle to remove the moss, then the surface cleaner to clean the rest of the surface. It went much faster that way. On surfaces that weren't moss-covered, the surface cleaner did a great job on its own. There was no over-spray, even on the uneven, natural stone walkway. I have never used any other surface cleaner, so I don't have direct experience to draw on, but I think this one is ideal for a homeowner. It's light enough that it floats over concrete surfaces easily, but if you were working with a really large area, you might want a surface cleaner with wheels. On the other hand, the fact that this one is so light and maneuverable made it possible for me to do the stairs on the deck and to get closer into corners, which I suspect would be difficult if not impossible with some of the other surface cleaners. The Greenworks 15" Surface Cleaner appears to be made well, and has a brush skirt that keeps it off the surface you're cleaning. It looks like the skirt is replaceable, though I have not looked on the Greenworks site to see if it's offered. The 12" extension the surface cleaner comes with is a great addition; it puts the cleaner exactly the right distance from me while I'm using it. There were no leaks, and it was easy to rinse the dirt out of the cleaner after use. If you're looking for a well-made, useful addition for a pressure washer up to 3100 PSI to clean a variety of flat surfaces, I wouldn't hesitate to buy this Greenworks product.

Overall, this surface cleaner works pretty well and does make cleaning larger concrete areas easier than using a standard pressure washer nozzle. My biggest complaint is that the spinning nozzles occasionally seem to get hung up or gummed up and don’t spin as freely as they should. When everything is spinning properly, it does a good job, but I’ve had to mess with it a few times to get it working correctly again. It’s a useful attachment and I’ll continue using it, but it’s not something I’m completely impressed with. For the price and what it does, its not too bad

I’n actually shocked such a cheap, plastic gadget works this well. I live in Seattle where the joke is “keep moving before moss grows under your feet”. I used this thing on my concrete walkway much like using a vacuum inside the house. It made a two hour job about 2min. I didn’t have thick moss to remove but a thin layer of discoloration. This cheap gadget works.

I used this very inexpensive washer attached to a underpowered electric Greenworks pressure washer. It is not a professional model and the 12in diameter means some additional effort is required, but I was impressed how effective it was at cleaning my driveway. If you set your expectations appropriate to the size of the washer and the attachment, it will get the job done. Perfect for home use.

So my husband really wanted this surface cleaner to go along with the new GreenWorks pressure washer he just bought (GPW2000). However, while using it he was unsure if it was really saving him that much time so we did and experiment. We timed him pressure washing one part of the driveway with just a regular spray nozzle, and another part with this surface cleaner. In 15 minutes he was able to clean about 5 square feet more of area with the round surface cleaner. To put it perspective a regular nozzle did about 100 square feet (10 by 10) in that time and the surface cleaner did 105 square feet. Also, he didn't get as wet using this attachment because there is no spray-back. However, the kicker is that it doesn't clean as deeply so the portion of the driveway he used it on didn't look as good as the portion where he used the regular nozzle. He is thinking that the bristles that allow it to move across the surface hold some of the water under the head resulting in a pooling effect, which makes the sprayers less effective. I imagine that while this is an issue for a driveway (solid surface) it wouldn't be much of an issue on a deck (slotted surface). So in the end, it does do the job a bit faster but not as thoroughly....at least when it comes to driveways.

Love it I wish I had bought this a long time ago. Great for cleaning up a cement patio.

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 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.
