ABSTRACT:
A vacuum cleaner floor tool is provided which comprises a housing formed by upper and lower members which mate with one another along a single plane inclined with respect to the base plane or bottom of the lower member. An air-powered turbine motor is positioned in the housing and includes a turbine chamber for the turbine motor, and a rotary floor agitator is provided which partially extends from the housing. The agitator is coupled to the turbine motor and is driven thereby. A base plate is removably mounted on the housing and forms a portion of a wall thereof, with the agitator extending from the housing through an opening in the base plate. Air passes through the opening in the base plate into the turbine chamber. The base plate includes a ramp which extends from the base plate into the housing, where the ramp and a portion of the turbine chamber form a nozzle for the turbine motor.
