I bought this stainless steel surface cleaner a couple of weeks ago and used it for the first time this past weekend to pressure clean my driveway. Driveway was completed much faster than what I expected and driveway came out much cleaner than when using my previous Simpson surface cleaner.
This is my second purchase of a surface cleaner but the Westinghouse unit (with plastic housing unlike the stainless steel version depicted) is far superior to my first cleaner (non-Westinghouse brand) due to the castor wheels making it easier to move the unit back and forth.
