Purchased this after returning a different brand. The other unit wasn't cleaning the way it was described. This Westinghouse however has done a great job. Very consistent in the cleaning path. It works perfectly with my electric PW. Highly recommend!

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.

Saw this on social media and until then, had no idea adding this to my electric pressure washer was even possible! I have a Greenworks 1600 psi and it attaches to the nozzle perfectly. I used it for sidewalks around my home and it saved to hours of time!

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 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.

My 3400 is not powerful enough to get the best results from this PWSCSS. It's well built and does the job, but with only 2.6 GPM, I don't think I am getting the full potential of this surface cleaner. On very dirty surfaces, it takes an extra pass to avoid striping, which means more time to clean.

I just received my 15" surface cleaner and it works wonders compared to using the wand with a normal nozzle. The job time went from nearly 6 hours down to 90 minutes for my 50' x 18' driveway plus 100 sq ft area of sidewalk approach. My only advice is to rinse with normal wand after each section of cleaning with the attachment to wash away loosened debris.

Bought this a few days ago. Used for the first time today. Took all of 30 seconds to pull it out of the box and hook up to my pressure washer wand. Cleaned half the inside of a garage that had caked on and ground in dirt/magnesium/salt from winter roads in about 10 minutes. Huge difference. Thrilled with it. Seems to be made very well, solid, stainless steel, and the casters are a great touch.

Using a surface cleaner head is a great way to reduce overspray and mess when pressure washing. This one is well built with metal wheels; no dragging across the pavement all day. The only downside is that it does not wash the debris away from the washed area and the standing dirty water where you worked makes it a bit difficult to tell if you are done.

Normally used a standard pressure washing tip to clean a 30-foot aggregate walkway and stoop. It would take quite a while and a good deal of water. The Westinghouse 12 inch surface cleaner easily cut the time in half and appeared to use much less water for the entire job. My 1600 psi electric pressure washer had no problems with the attachment. Should have bought this several years ago.
