Masterblend once sold that unit, painted blue. I had one and it is a great scrubber, just unreliable as hell. Actually has WOODEN gears or did back then. I found a place to buy the plastic gear replacements but they were $80 each. Due to the frequent break down of the machine we unloaded it. Get some replacement gears on the truck, Ron. Go with the plastic ones, avoid the wooden like the plague. For your sake I hope they have improved the thing because they were no where near as reliable as the Whittiker. The enhanced scrubbing is all about the type of brush. I actually loved the machine just hated the constant issues it had. It does rock on steps !
