Abstract
A floor sander comprising a drive motor, a horizontal rotating drum having a top and a bottom driven by the drive motor and a housing covering the top of the rotating drum, wherein the rotating drum supports and drives sandpaper continuously, and the bottom of the rotating drum is exposed to sand a floor; wherein the floor sander has a blower impeller driven by the shaft of the drive motor to create an air flow that is fluidly conducted by a channel mounted on the outside of the housing and the air flow is directed toward the rotating drum to cool the drum.
