Abstract
A drive belt shifting arrangement for a rotatable brush roller of an upright cleaner where the shifter has an idler pulley for arcuate movement within the loop of the belt between the roller and the motor occasioned by pedal actuation. The same pedal action by the user alternately cams the belt onto the idler pulley to discontinue roller rotation or to permit its movement back to the motor shaft to allow roller rotation.
