I bought during the winter months, so I haven't had a chance to use the pressure washer surface cleaner, but at first glance, this product seems solid and connected easily to my Sun Joe pressure washer.
Just purchased the Westinghouse 15” surface cleaner and hooked it up to my 3200psi Westinghouse pressure washer the day it arrived. Living in the PNW everything turns green this time of year including driveways and walkways. This attachment made short work of heavy moss and dirt and I had my cobblestone driveway back in a little under an hour. So much better than normal pressure washing and amazing results. Great way for the kids to earn their allowance.
