I tried it out yesterday with my gas power washer. Worked as mentioned. The other reviews that I read prior to my purchase coincided with my results. Did a great job, and in a lot less time than moving a spay wand back and forth. No more so wrist from moving wand back and forth.

Works great! Significantly limits water spray back into clothing. I used it to clean pavers. I did have to use regular nozzle in areas where some pavers were very uneven, but most of the pavers cleaned very well without extra work. Works best by pulling backwards. By concentrating water within the unit, it helps easily dislodge debris from cracks. Much more gentle on the body than using only wand to clean. Faster cleaning than wand only

The Westinghouse Surface Cleaner is a must have! This makes cleaning your driveway and walkways much easier. Normally I spend a few hours and with this accessory the task goes much faster and without having neck pain and sore arms. I never knew that these make such a big difference in performance.

My brother-in-law owns one of these and he and myself cleaned the sidewalks at our church recently. This item made a huge difference without having to use a wand to tirelessly go back and forth to clean. I knew I was going to have to own one of these to do my own sidewalks and driveway. What a time saver for making such a difference.

The Westinghouse Stainless Steel 16.5" Surface Cleaner is a highly effective and time-saving accessory for pressure washing, significantly reducing cleaning time on the sidewalk and patio. I'm also pleased with the ease of use and able to use it without back pain that regular pressure washing causes.

I spent 6 days with a single rotating nozzle pressure creating concentric 3" circles cleaning over 2500 sq ft of concrete around my property. No worries. It was really bad with a lot of stain and dead biological material affixed to it. I wanted the initial cleaning to be meticulous & complete. I bought this surface cleaner so that every two years I can easily & quickly maintain my clean concrete. It's heavy duty and I have no doubts that it will be able to handle the job for years to come. My aching back thanked me.

I just bought this 15" surface cleaner and the Westington House 3400 PSI pressure washer last week. I used both of them yesterday and they worked great. This 15" surface is awesome. It used to take me about 4 hours to pressuer wash my patio and yesterday it took about 50 minutes. This tool is awesome and did a great job cutting through the dirt that was on my patio. I wish I had bought both of these years ago!

If you even occasionally pressure wash your concrete driveway, patio, or sidewalk, you need this. It just works. Just attach it to the end of your wand with the quick-connect and go. It is so much faster and easier than using the wand. It doesn't remove everything with just one pass, so you do have to move back and forth and overlap a little as you go, but this is to be expected. When you do this, it cleans well. I used the wand to go back over an area that I first did with the surface cleaner, and I couldn't tell much difference. Because of the round shape, it obviously can't get into corners, and it leaves a small patch uncleaned right next to walls, so you will need the wand for those areas, but you won't care. This thing is a time-saver and a back saver. I wish I had bought it years ago. 5 stars.

Bought this in the beginning of May and cleaned the entire concrete patio around the pool. Small learning curve on the best speed to move the surface cleaner but once you find out how slow/fast you can move it, it's much easier than using just a nozzle.

I bought this last week and used it to clean our deck and patio. It works fabulously on the concrete patio, but struggles a little on the Trex decking. I expected this, though, as the decking is very dirty, and I am still very happy with the purchase since it saves so much work on the patio.
