I have ~12K sq feet of concrete to keep clean. The 16.5 inch disc enables me to complete the project faster. The wheels keep the spray at a consistent level and reduce the stress on my lower back.

Works great with exp3500 pressure washer especially for cleaning large area. My unit didn't come with the nozzle cleaner but a pin or paper clip should work just as well.

I bought the surface cleaner to help clean my driveway and sidewalks and this product worked perfectly. It cut down the time by more than half to clean my driveway.

I've been using this surface cleaner for over a month, almost ones a week, the cleaning path is very clear , this surface cleaner is very strong, exactly what i need it

I bought this in hopes that surface cleaning would be easier. It does!! Great tool, and love the extension wands! Would be a lot more difficult without them.

Easy to attach and cleans our large patio very quickly compared to using regular power washer attachments. Was concerned it wouldn't be powerful enough with our electric power washer but it was fine.

This attachment is amazing. What a time saver. I should have purchased it years ago. I use it to clean concrete surfaces around my pool and it does a tremendous job.

We bought this a few weeks ago. Our son used it to clean outside decking. The deck looked much better after having been pressure washed. The surface cleaner is a much quicker way to clean.

I bought this cleaner one week ago and finally got to use it. It does a very good job on my concrete as long as you don't move it too quickly. Take your time

If you want to clean your driveway or sidewalk, this surface cleaner is a must. It makes the job so much easier and quicker. I will recommend the 15" Westinghouse surface cleaner for a small to a medium size DIY project.
