I've used the Westinghouse metal 16.5 inch surface cleaner a few times already. It's a solidly built unit which works very well. I took off 1 star because sometimes the wheels don't seem to want to pivot with the unit causing them to rub instead of roll on the surface. I'm afraid that they will wear out prematurely
I went from a traditional gas powered pressure washer to the electric WPX3000e and was pleasantly surprised at the power and pressure it put out. It made quick work of my pool pavers and sidewalk. A great value for the price and a real workhorse.
