The 2 that we own are 20in BEís
Iím not that crazy about their dependably, we have had to replace the main rotor on both. I canít tell you how many hours we have on them but one went out only after a year and a half and the other six months later. One of them I had to send back to the company because it wasnít balanced correctly when shipped new. We donít use them everyday, but we maintain them well. We use them with a 3600 psi 13 hp pw. I would not suggest using anything with less psi and hp.
I would like to hear what others that use a surface cleaner daily suggest as the best, and why.
