An air-powered vacuum cleaner floor tool and an air turbine therefor are provided. The floor tool comprises a housing with a rotary agitator mounted on the bottom thereof, and a wand connector means mounted on the rear thereof and aligned with the longitudinal center of the housing. The wand connector is used for connecting the floor tool to a vacuum cleaner wand. The air-powered turbine motor has a turbine chamber and a rotor mounted on the housing, with the turbine chamber having an air inlet and an air outlet. The air inlet is aligned with the longitudinal center of the rotary agitator, and the air outlet is aligned with the longitudinal center of the housing and with the wand connector. The air outlet includes an outlet opening in the turbine chamber. The angle which is formed by the center line of the air inlet of the air-powered motor, and the center line of the outlet opening of the turbine chamber, is less than 55.degree.. Further, the turbine rotor is rotatably mounted in the turbine chamber so that the smallest area between the outer periphery of the rotor and the wall of the turbine chamber is equal to substantially one-half of the area of the outlet opening of the turbine chamber.
