i have not used yet, but looks like it will do the job

I bought this to do some bad cleaning on concrete. Mold and dirt. Did great!

I have used these before and it is hit or miss but this one works really wel.l

Well, worth the price. I enjoyed cleaning my deck myself!

Works great. Good value it cut my pressure washing time in half and did a wondetjob

The design looks great and the overall size is nice.

Bought this to with Westinghouse 3400 PSI Pressure Washer and both work flawlessly.

Arrived as expected and will help out immensely on large projects.

Best value, goood quality, compatible with other products/brands.

This has been one of the best concrete surface cleaners I have ever used.
