After researching the many popular brand name surface cleaners, I chose this one based on its much better PSI/GPM numbers. No pun intended, but this one blows the others away. Looks to be well built, and stainless steel to boot. The bonus is that this comes with a couple of wand extensions, so you're not spending time all hunched over while using it.

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.

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.

The Westinghouse 16.5 in. 4000 PSI Surface Cleaner exceeded my expectations in both performance and durability. The all-stainless steel construction, with no plastic parts, gives it a solid and reliable feel. With its large coverage area, cleaning surfaces is quick and efficient, saving both time and effort. It works exactly as described, handling even the toughest cleaning tasks with ease. Highly recommended for those looking for a professional-grade pressure washer accessory that's built to last.

I only recently took delivery of this surface cleaner and haven't yet put it to use on the driveway or sidewalk, but based on the design, quality of the materials and workmanship I'm confident it will perform well. I looked at others online and at a local store and chose this one because the difference in quality was readily apparent.

Purchased this item to help streamline cleaning flat surfaces around my home (driveway, sidewalks, deck, etc.). Pleasantly surprised at how well this item works! Speeds up cleaning surfaces vs. using the traditional pressure washer wand/tips. Does a really good job removing dirt/grime. Easy to use as well, clicks right into the quick connect at the end of the pressure washer wand. Saves a ton of time, great accessory to add to your tool stash!

I bought this to clean 2 large concrete pads and a concrete sidewalk at my new house. I also bought a concrete cleaning detergent but didnt end up needing it. This cleaner worked beautifully. It was easy to connect to my pressure washer and made quick work of the surfaces.

So much faster to clean concrete than using spray nozzle. Tougher jobs you have to go over a couple of times. I recommend using an extended wand so you don't have to bend over. I should have taken before and after photos but didn't think about it until after. Concrete pad toward bottom of the photo is the older slab when house was build and we added to it later so that is why two different colors.

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 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
