Works just fine. I cleaned a driveway with it, making it much faster than just the wand. I would do the edges of the driveway with the wand, and then go over the rest with this attachment, then spray down with the wand every 6 feet or so. Go slow and steady, overlap by about 1/4, to hide any lines.

I purchased this product after researching a few other options. I wanted something that was sturdy and capable of getting the job done. This product never fails to disappoint. It's large capacity helps to cover a broader cleaner area with less passes. It's light enough for easy handling and sturdy enough to handle to hard jobs. I am glad I decided to go with this product.

Used on pressure treated deck. Some boards a year old, some 42 years old. The 16.5" surface cleaner was paired with a 3600 psi, 2.5 gpm pressure washer. All the board surfaces were cleaned very well with none of the unsightly marks common when using only a pressure washer & fan tip.

Finally used this yesterday. I was surprised at how well it cleaned my deck, driveway and sidewalk. The trick is to go slow and go over same area twice. It's so much easier than using just the spray wand on the pressure washer. As long as you don't have a ton of buildup this works great.

I Purchased this surface cleaner to clean my garage floor and deck and it did a very great job on both. I Recommend that you get one the water spay is Contain under the cleaner head so you use all of the power of the Pressure washer at a Constant height

This surface cleaner is smaller in diameter and the maximum pressure is the same as my electric pressure washer. I think the smaller diameter makes a difference in cleaning the area. I am switching from gas to electric pressure washer, it is a great product to add to my electric pressure washer

I actually purchased the PWSC15. I've recently tested four different Power Washers and this unit is by far the best, and most economic, too! It is reasonably quiet and does not tend to lift upward like others can. I appreciate the offer to obtain extra tips and a clean kit.

My 3400 is not powerful enough to get the best results from this PWSCSS. It's well built and does the job, but with only 2.6 GPM, I don't think I am getting the full potential of this surface cleaner. On very dirty surfaces, it takes an extra pass to avoid striping, which means more time to clean.

I am very happy with my purchase of the Westinghouse 15" surface cleaner attachment. It was a lot easier to use than I thought it would be. I used it to power wash away the dark mold and mildew on my driveway and the sidewalk in front of my house. Last year I did the same job using only the power washer stick. Using the surface cleaner disk makes the work go so much faster and easier.

Saw this on social media and until then, had no idea adding this to my electric pressure washer was even possible! I have a Greenworks 1600 psi and it attaches to the nozzle perfectly. I used it for sidewalks around my home and it saved to hours of time!
