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

Surface cleaner works well. It saves a lot of time than using the a nozzle. A little cumbersome to move left/right/forward. It moves best pulling toward you. You may want to purchase something with wheels if cleaning larger areas or cleaning on a regular basis.

I used it to clean 16" sq. tan patio blocks which were very dirty with black and green build up from the winter. After taking it slow I was very impressed and satisfied with the out come. Also it was quicker and less messy than using the single nozzle.

We needed to clean our large patio. We moved into the house last year and this hasn't been done in at least 5 years, so it was filthy. There was no way I was going to spend hours upon hours using a nozzle, so I researched and bought this instead. It still took time because of the large area and the degree of dirt, but wow. Attached photo is after 1 pass, I'm going to go over it again. Tips: A- I'm 5'4 and could use this comfortably, if you're any taller you'd probably want an extension piece. B- The most efficient way to use this was to pull it towards me while I stepped backwards. (your feet will get wet! wear proper footwear) C- It did tend to get 'stuck' at times (the spinning slowed/stopped). Cleaning with the supplied pick didn't always help, I found that manually taking off any debris accumulated from the center helped. And to check if the issue was resolved, I'd pick it up off the ground and turn it on until it span normally.

I had done a lot of research before purchasing this product.This is my first experience with a surface cleaner.There is absolutely no comparison..... Westinghouse in my opinion gives you the best product at a reasonable price.None of the others offer a stainless body,none of the others can cover the surface area.The product having wheels is a game changer.It cleaned so well I don't even feel I need to pre-treat the concrete with a cleaner.The least amout of chemicals I have to use the better!! Thanks for making an awesome product for an affordable price

I added an additional cleaner for my pressure washer. I have a Briggs & Stratton cleaner that works just fine but this one cleans a larger surface and moves much easier with the installed wheels. The stainless steel construction will last much longer than a plastic cleaner. I use this to clean my pool apron and long concrete driveway.

I purchased this 12 in. Surface washer last month and took it out of the box this weekend. For the price, I was not expecting a great result in cleaning my deck. To my surprise the cleaning was better than expected. Attaching it was easy, moving it along my deck boards was easy. With my pressure washer only being a 2500 PSI machine, I was very impressed with the results. The only note I’ll make is that I still needed to use my nozzles for the corners of my deck prior to using this device.

I used this for the first time on an asphalt driveway with heavy moss. It does a good job covering a large area, however, on a flat surface the dirt, moss, and water puddle where it is washed making it extremely difficult to see if the area is clean or not. I had to go over the are again with a spray nozzle to wash away the dirt and moss.

Purchased to clean the driveway and a sidewalk at our church. Did a fantastic job. I'm sure such items at a greater price, with wheels and such, may function better, but when I let the water pressure do the work it just skimmed along the top of the concrete and did the job.

I received this as a gift - it was supposed to be compatible with my littel electric Sun Joe SPX200E power washer. It took me a little while to find the right adapter to make the end of the SunJOe wand fir the 1/4" connections, but it is available. Finally got to try it out today - it really exceeded my expectations. Moving the surface head along about a foot per second left the concrete fully clean. The thing is quiet, and my washer doesn't generate huge pressure, so I was really impressed by how such a wide swath was cleaned so quickly. I'm looking forward to using it on other surfaces, especially the swim deck on our dock.
