I am suitably impressed. I have a Simpson 3100psi power washer with the Honda GC190 engine. I also have a big driveway, and I power washed it the other day using an old 15" spray disc with no wheels. By the time I was halfway finished I'd already decided to save my back and buy a spray disc with wheels- preferably 4 since I was worried about dropping a wheel off the sidewalk or into an expansion joint and I assumed a 3-wheeler would get high-centered with only 2 wheels on the ground. So I picked out this 16.5" Westinghouse. When it arrived, I wanted to try it but with the driveway recently completed I had nothing left to clean; so to the amusement of my neighbors, I went out and power washed the street in front of my house- years and years of concentrated dirt. To compound things, my neighbor on the uphill side (God bless him) had decided to spray all the mud and muck off his sidewalk and into the street, which flowed downhill and settled nicely in the gutter area in front of my house as well. So all in all, it was a nice test. Here are my impressions: First, this thing is heavy. You can lift it ok when attached to the wand but I can't imagine trying to lift it when using the extensions that come with it. Second, this thing rolls like a dream. It rolls forward and back and sideways with almost no effort and changes direction with no hesitation. I was frankly surprised, since this is what I was hoping for when I gave up on my old disc in the first place. It rolls so easily it kept trying to roll away from the natural crown in the street and bump into my curb (it's heavy, remember?). I learned to compensate my strokes, and after a while we got along fine. Third, it does a fair job at removing dirt. Thin layers of dirt in the street came up in one pass, but as the dirt thickened and became darker I had to run over it 4-5 times, and even then it didn't get all of it. For those spots I went back over it with the green 25 degree nozzle, and it still only came up with difficulty. It is rated to 4400psi - perhaps if my machine was more stout I'd be writing different words here. But I suppose there's a balancing act going on - more power, jets closer to the ground, etc. would make dirt removal better but it would also etch my concrete driveway more. As it is I think this disc and my driveway will become fast friends. I do recommend it, even with the weight.

Great product. This made a world of difference. It was easy to use and cleaned evenly and smoothly. It didn't leave the striping that you can get using the pressure washer alone. The wheels just glide along and the dirt and grime are blasted away. If you are cleaning a flat surface like a driveway, patio or deck, this is a must have product.

I have used a less expensive brand surface cleaner put because it was made of plastic it was hard to keep down on the ground. This unit has a good weight that makes it easier to control with less fatigue. I'am using a 3000 PSI unit. The attached wheels allow easy control and if you get to close to the edge of a step the stiff brush will not allow the nozzles to bottom out and damage them. I do wish that the quick disconnect pipe was a bit larger diameter it just feels a little light duty for the weight of the cleaner. All that said have not had any problems.

Very pleased with this Surface Cleaner overall. It does a great job of scrubbing the dirt and grit off of my driveway, but in order not to leave streaks you do have to go over it twice, once side to side and once up and down. One thing that stood out was that the quick connect stem didn't move back and forth easily. A quick shot of lubricant had the problem solved quickly.

I bought the 16.5” surface cleaner with my recent purchase of a 3400psi Pressure Washer. It is so smooth and does an amazing job, by far the best of this type of product I have used. I have cleaned about 8000sqft of concrete so far and it works better than expected.

Bought this last week, but used it for the first time today. I exceeded my expectations. It cleaned my driveway with ease and used my pressure washing time in half. The two extension rods made the job easier. I'm glad I bought it with wheels moving it forward and backwards was effortless.

I just received my stainless steel surface cleaner and used it cleaning my driveway. The wheels made it very easy to maneuver and it cleaned the concrete with one pass. I used it with a 3400 psi gas pressure washer and I couldn't be happier with the results. Highly recommend.

Bought this after seeing it in action and talked to the person using one. I still pressure my edges and corners then hook up this surface cleaner and bang I'm done in half the time it used to take me. Also I know I'm using way less water. Great accessory to have.

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.

I just received the PWSC12 12" surface cleaner. While I haven't had a chance to put it to work, it appears to be robust and well made. I especially like the brass nozzles. I also like the solid brush skirt that is about an inch long as it contains no gaps between the bristles. The wand connection seems solid with no play where it connects to the main unit--this indicates to me that there will be no leakage at this junction. The only surprise was the little cleaning tool that was included for the nozzles--I almost missed it as it was just laying in the bottom of the shipping box. Overall I am very pleased with this purchase so far and I can't wait to give it a go on my patio, sidewalk and garage floor.
