I have used this item twice now. It is cleaning the white residue off of the back paver patio and I look forward to using it on the garage floor after it snows this weekend! It is great for a quick car wash and to wash weatherteck type car mats. I like all of the options (high pressure, moderate, and soap nozzles. The only question I have is...why didn't I buy one of these many years ago? ;-)
