Recently purchased this surface cleaner to clean my driveway/rv pad/sidewalk and entry. It worked as advertised and saved a huge amount of time vs using a nozzle. I previously purchased brand R and went through two of those in 3 usages. They worked fine for the first two times, but after that either quit working or started spewing water out of the top. This Westinghouse cleaner has worked fine after a good workout so am hoping the next time I use it I won't have any issues.
