My 15 year old driveway got it's first pressure washer wash yesterday using the 12 inch surface cleaner. The surface cleaner works with a lot of help from the brushes on the bottom of the cleaner. It takes some additional work to utilize the action of the brushes. I changed the surface cleaner with the turbo nozzle. I found the result about the same plus it was less work. Next year when I clean my driveway, I will try the surface cleaner again and anticipate the job will be far easier with only a one year surface than a 15 year surface.
Bought the surface with the 3000 PSI Pressure electric pressure washer. The surface cleaner is made of heavy plastic and appears sturdy. Works as expected.
