The addition of the surface pressure cleaner accelerated the cleaning process. It slides easier on tiles than concrete. It complements the use of my existing nozzles, the latter I still used to wash area covered with the surface cleaner and edges where the cleaner could not reach. I estimate a productivity increase of 25% by using the surface cleaner to just the nozzles.
Bought this surface cleaner together with 2700 psi pressure washer. Looks rigid and durable. Coverage area is good enough for the driveway and lanai floors.
