Great accessory for concrete surface cleaning. We have a damp, always shady front patio which grows green mildew everywhere.

Just purchased this product after a week of serious research on all models. Was quick to assemble and easy to operate. Works better than expected and is light to move around.

Bought this surface cleaner last week and cleaned my driveway with it. It did a great job. I like the fact that no water sprays out from under the unit. Very satisfied with this product after only 1 use. Highly recommended!

I just bought this surface cleaner and it is a great addition to my pressure washer. Great for cleaning large surfaces like my patio and walkway. Cleans quickly and thoroughly and is a time saver!

Though I've recently received the unit I have heard from neighbors that this product made their job much simpler pressure washing their driveways. I feel confident I will have the same or similar results.

I've used this one time for a few pieces of sidewalk so far and it did a good job. I followed up lightly with the pressure washer to rinse dirt off the surface. So far so good and I'm happy with this attachment

This surface cleaner is a great product. It makes pressure washing your patio very easy, and alot faster. One pass with this product and the surface is clean. I would highly recommend this product if you are looking to clean your patio, or driveway.

Wow this thing eats right up the grim in one stripe with my 4000 psi honda pressure washer. Tried others nothing like this. Buy this won't be disappointed!

I received this for Christmas and I'm excited to try it out for myself. I've cleaned my patio in the past and I always end up with streaks. Can't wait to see how this works.

I have large areas of patio and driveway to wash. It would be difficult and time consuming using just a regular pressure washer wand. The 12" surface washer reduces the time greatly saving water and also strain on the hands and back.
