I’ve used it for cleaning outdoor teak furniture, concrete pool areas, bbq area, artificial surface deck, driveway, and a stone tiled porch using the standard attachments and the surface brush attachment. It worked well on all surfaces without any detergent except the stone tiled porch. Great for the environment!
I have only used the pressure washer two times, once to clean latticework and the other to wash the car. I purchased it for cleaning siding, gutters, outdoor furniture and wood decks. Based on how it has worked so far I expect it to perform well on the other things I want to do. With Spring coming I will be using it frequently and for long periods of time. I will soon know of it is worth 5 stars or not.
