Can't find the serial number but it works very well any way. did a good job on my driveway and deck...

I just used it yesterday, it really cleaned my driveway very well. I give thumbs up for it as I can see a big difference before and after.

Bought as an accessory to my wpx3200e, does a great job of cleaning off sections. Cab really see a difference between the spots it was used and not.

I moved into an older home and the driveway and area around the pool had never been cleaned so I bought this surface cleaner and it worked wonders...

Received this today and tested it on my one year old decl Night and day difference in just a few minutes.

The surface cleaner worked perfectly. It removed all the mold and mildew from the driveway and sidewalk. I’m really happy with this product.

Wish I had purchased one years ago, but adding this Westinghouse power washer surface cleaner cut my washing time in half and saved my back! Very happy with the results.

I love the 15” surface cleaner! It is so easy to use and does a great job cleaning the dirt and stains off my patio and drive way. Would buy again and 100% recommend it to others!

This is my 3rd surface cleaner, but 1st Westinghouse brand. Good price and works well. Wish it moved more smoothly over the surface, but otherwise performed fine. Would purchase again.

I just bought it so I haven't had a chance to try it, but the quality seems good. The diameter is a good size and should help shorten the time to clean my driveway.
