I’m looking at buying the mosmatic 12" recovery surface cleaner to clean apartment stairwells without swamping them. Thing is, I run an 8gpm machine so I don’t know if it can handle the flow. The websites that sell it don’t list max flow or if they do they’re conflicting (one says max is 5.5gpm and another says 13gpm for an 8" graffiti cleaner version).
Just bought this to do the breezeways on the advice of someone who does lots if apartments. Mainly because this won’t clog up with dog hair like the comparable mosmatics. Still need a smaller one for stairwells. Will not be spray gunning those.
