Greenworks 11" Surface Cleaner Universal Pressure Washer Attachment

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.

I just washed my driveway with this, and it worked very well. I was using a Dewalt DWPW2600 2600 PSI electric pressure washer. Wow this sped things up! It works really well on smooth concrete. However, there is part of my driveway that is very course. It's more like stones that are stuck together with cement. That part of the driveway was hard to wash, because the GreenWorks surface cleaner doesn't have wheels. I think a more expensive product with wheels would have worked better there. However, if you have a typical driveway made of smooth or brushed concrete, then this works great! I would give this 4.5 stars, but I'm rounding up to 5.

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.

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

This attachment actually works really well! If you’re looking to give your driveway or patio a quick cleaning, it’s a great time-saver. But if you’re trying to remove years of built-up dirt and grime, nothing beats the regular 25° or 40° pressure washer nozzles. I’ve attached a few pictures so you can see what I mean. The darkest concrete is completely unwashed, the lighter areas were cleaned with the surface cleaner attachment, and the lightest areas were cleaned with the regular nozzles. Here’s what happened: I started with the surface cleaner attachment, and it definitely made a difference! But there were some stubborn spots it just couldn’t get clean. So I went back over those areas with the 25° nozzle, and the concrete was noticeably lighter! The difference was so obvious that I ended up having to go over everything again with the regular nozzle just to get an even color. So here’s my advice: If you’re just doing regular maintenance, this thing is great! It’ll save you a ton of time and effort. But if your driveway hasn’t been cleaned in years and you’re looking for that really deep clean, I’d skip the attachment and go straight for the regular nozzles. One more thing: If you’re tall, do yourself a favor and get an extension wand! Otherwise, you’ll be hunched over the entire time, and your back will definitely feel it. Overall, I’m happy with it! It does what it’s supposed to do and easy to use, but I think it’s important to have realistic expectations. Great for maintenance, just not quite powerful enough for the really stubborn stuff.

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.

Working well with our Greenworks GPW3000 pressure washer. This is 3x faster than using any of the wand nozzles. It is very easy to pull along coarse surfaces like concrete but doesn't push well. Some weight has to be lifted to get it to push smoothly. It also needs to be moved a little slower than I expected (slower than vacuuming). This surface cleaners comes with the extension which is mandatory unless you're under 5-feet tall or you hate your back.

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.

The Greenworks 30012 patio stone cleaner is a high‑value, time‑saving attachment that delivers excellent results on patios, stone walkways, and driveways.

While it struggles with tight corners and very deep stains, it remains one of the most efficient and user‑friendly surface cleaners in its price range. If you want a cleaner that dramatically speeds up patio and stone maintenance, this model is a strong choice.

Really does it's job! Easy to use, absolutely satisfied
