Westinghouse Outdoor Power Equipment PWSC12 12" Surface Cleaner, Blue

Although I was using a 3000 psi pressure washer it functioned very well. Note the electric pressure washer was 3000 at 1.75gpm, would have had a slight pressure drop across as 50'hose so I thought I was safe to use this. I moved slow and passed over each spot twice. That way it cleaned without leaving swirl marks. The algae build up on parts of the cement was rather thick. It did a good job cleaning it off. Note, knowing how dirty I still used Jomax and bleach according to the package directions and sprayed this on to the surface. I let it sit for 10 minutes before beginning to clean the surface. Once the surface was clean I floated the dirty water off of the surface with a 25 deg nozzle. This worked very well. The material this is made out of should last and appears to be of good quality. It's light weight will make it easy to do walls as well.

Normally I don't take the time to write reviews but the value proposition offered by this product is terrific. It's affordable, reasonably well made and it does a good job. I have an 1800 PSI pressure washer that pumps out 2.0GPM. This unit can take up to 2500PSI and 2.3GPM. This is marked on a label attached to the unit. The product listing mentions the 2500PSI but not the 2.3GPM maximum. This make this unit a great attachment for an electric pressure washer. I had about 200 square feet of interlock that was in a very dirty state and another 500 or so square feet that were not as dirty and full of weeds in between the stones. My task was to clean the surface of the stones and then use a fine-point pressure washer nozzle to remove all of the old, decrepid sand between the interlock stone and get it ready to apply new polymeric. The surface cleaner did an outstanding job. It saved me what would likely have been hours of using a pressure washer wand to clean the surface. It saved me so much time and energy that I vowed that if I broke the surface cleaner I purchased, I would keep buying them until I got the job done. The one downside of this surface cleaner is that it is made of plastic. This unit isn't going to last me for 10 years cleaning the interlock every year. Frankly, if I get a year out of it, I'll consider it a massive return on my investment. That being said, it gave me no issues whatsoever and worked very well. I have recommended it to several other friends with electric pressure washers. For the money, its a very good tool. I have attached two photos of the walkway in disgusting, dirty condition. Both show it nice and clean while one shows how dirty this walkway was beyond the fence, which I'll clean later.

The Westinghouse 12" pressure washer surface cleaner attachment is a total game changer. It made cleaning my driveway and patio so much faster compared to using a standard spray nozzle. The 12-inch coverage area saves a ton of time and gives a much more even, streak-free finish. It feels solid and well built, and it handled my pressure washer’s output with no issues. The 1/4” connector attached quickly and securely, so setup was simple. If you’re using a pressure washer regularly, this attachment is absolutely worth it. It delivers consistent pressure, great coverage, and professional-looking results. Easy 5 stars.

super easy to use on vertical surfaces, awesome for cleaning windows. used it on metal roofing that in the past I had used a regular wand attachment and was never very happy with the result, this cut my work time by 75% and did an excellent job. I would say it payed for itself on the first day

it works as well or better than using just a power washer. The skirt keeps water from splashing and i was surprised that for such a light unit it stayed practically glued to the ground. well worth the cost. It cleans concrete as well as a wood deck. I suggest moving in slow steady back and forth motions - not fast.
