I searched for some time to find a surface washer that was wide enough, on wheels, and made with stainless steel. This one met all the criteria that I had and at a very reasonable price. It is actually as advertised and is solidly built. Very satisfied.

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.

I bought this a month ago and just used it for the first time yesterday. I was not sure what to expect since I had borrowed an older cleaner (different brand) from a neighbor a couple of years ago and was very disappointed with its performance. I have. 3100 PSI gas-powered pressure washer and, as soon as I turned it on, the results were amazing. It almost glides over the surface (concrete patio, porch & sidewalk), and cleans beautifully.

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.

The Westinghouse PWSC12 is a great addition to our power washer setup. It's easy to connect and significantly improves cleaning efficiency on driveways, patios, and other flat surfaces. The rotating jets provide consistent pressure while minimizing splash-back, and the durable housing handles heavy use well. A must-have accessory that makes large surface cleaning faster and more effective.

Bought the 16.5" washer recently. Used it to clean the decks on my house, the pier to my dock and my dock. I have only glowing reports of the the quality of this washer as well as how well it worked and how much time it saved me. First time pressure washing in years and now all look great. Would highly recommend this product and would or will gladly buy another if or when I wear this one out!!

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.

This is a great surface cleaner. Saved me so much time cleaning my drive as compared to using the wand, as I have for years. Did a perfect job and I actually enjoyed the task. I have a 3700 psi pressure washer and it left my drive perfectly clean. You will need to use the wand to wash off all the residue from the cleaning. You won't regret buying this one. It's one of the more affordable units with a high customer rating. Great value for you money!

Was looking to purchase a pressure washer surface cleaner for some time. Investigated all types and read many reviews. Ultimately decided on the Westinghouse 15" surface cleaner. It is generally priced below the competition and has been very effective. It is a simple design with few moving parts while doing a great job in cleaning. No wheels to break, just hovers from the pressure of the nozzles and moves quite easily. Best to move in a backward (pulling) motion instead of forward. Remember to verify your pressure washers gpm and pressure output as to be sufficiently strong yet not to over power. Overall am very happy, so much so I recently purchased another for my spare pressure washer (one I loan to friends and family). You won't be disappointed.

So far I have used the unit to clean a back porch which is a concrete slab. The unit is infinitely better than just using a wand with a turbo nozzle or standard spray bits. It is incredibly quick and consistent. I have found that on a level surface one handed operation is possible as the wheels work so well. The splash guard on the unit also works great and I have not had any splashing/spraying outside of the unit. The construction of the device itself is impressively stout. I would purchase this product again. Currently this is being powered at 3200psi at 2.3gpm.
