Miskini, Richard (speedqueen),
Miskini, I am not familiar with that Rug Doctor. It is a different machine than the ones they sold at a higher price.
Richard, The usual failure with a Hoover spinscrub is a blocked air way screen to the turbine that turns the brushes.
Yes, at least on the older models, the brush is air driven. A simple repair to clean it out.
The Floormate has an electric brush motor.
P.S, did you notice my location neighbor?
