A vacuum cleaner floor tool is provided which comprises a housing, an air-powered turbine motor in the housing and an agitator partially extending from the housing. The agitator has spiral grooves therein which hold agitating devices, such as brushes or beater bars, and one end of the agitator is reduced or turned down to form a reduced diameter portion. The diameter of the reduced diameter portion is such that the spiral grooves form substantially flat surfaces and these surfaces are engaged by lugs on a connector fitted over the reduced portion. A transmission belt interconnects the connector with the turbine motor in order to drive the agitator. The floor tool has a removable base plate mounted on the housing which forms one wall thereof, and the agitator extends from the housing through an opening in the base plate. A manually operable base plate retaining device is mounted on the housing to hold the base plate in place during operation, with the retaining member being easily operable to allow for removal of the base plate. A bumper strip is mounted on the housing and surrounds the housing. The bumper strip includes a lip which extends therefrom and engages the base plate in order to form an air seal therewith.
