Westinghouse Outdoor Power Equipment PWSC12 12" Pressure Washer Surface Cleaner Attachment - 2500 Max PSI, 1/4” Connector

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.

This light weight attachment is very easy to connect to a pressure washer and use. The brushes along the edge do a decent job of scrubbing surfaces and the water sprayers underneath work well. I've only used it a few times and it seems rugged enough, but it is a plastic unit so it's not for industrial uses. The 12" size is good enough for most household jobs and the attachment is fairly quiet when in use. My only critique is that I wish it had casters or wheels on it, but that's clearly not part of its design. In the box there was a card for free sprayer nozzle tips, so that was a cool bonus.

This cleaner was awesome. Just did my patio and it was easy with this unit and did a great job. Will do my driveway next if it only lasts till that job is done then well worth the money for me. I think it will last longer as it really doesn't feel like it is cheap. Happy with this purchase.

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.
