Abstract
A floor sanding machine is provided with a pair of sanding discs, each of which is driven by an individual variable speed electric motor. Individual controls on the handle of the floor sanding machine control the speed of each of the individual motors so that the sanding machine can be guided in a desired direction by changing the speed of one or the other or both of the electric motors.
