I bought this about a month ago and just got around to assembly and first use when a car stain on the driveway and a rusty drip spot on the concrete front stairs came up. The instructions were easy and clear and the washer went together in a flash. Hooked up the power and water and got to work. Because both jobs were concrete, I used the high pressure nozzle and water only. The stains were blasted off and clean bare concrete remained. Worked like a charm and the deck and siding are the next test for lower pressure nozzles and soap. The wheels on my wife's car will follow. Very satisfied.
