    摘要： A nozzle assembly for a vacuum cleaner is provided with floor engaging wheels that are frictionally engaged with and rotate additional wheels that are secured to the ends of a brush in a manner such that rotation of the additional wheels causes the brush to rotate. As the vacuum nozzle assembly is moved back and forth across a floor that requires cleaning, the wheels engaging the floor are caused to rotate thereby rotating the brush in the opposite direction. The latter agitates the carpet or other floor covering to loosen and direct dirt particles toward the inlet slot of the vacuum cleaner nozzle.

    摘要： A by-pass type wet/dry vacuum is provided with a removable lid assembly that includes an electric motor having a lower insulating housing, a cover for the upper end of the motor, a blower housing including vanes for regulating flow of main blower air, a fan having a pancake type impeller, a fan cover and a tank lid having an integrally formed float cage. Assembly of these elements is achieved by making all electrical connections between the motor, a power cord extending to the motor cover, and a manually operated control switch mounted on the motor cover; inverting the motor cover, inserting the upper end of the motor downward into the cover where the former is grasped by snap type retainers formed integrally with the cover, inverting the blower housing and securing same to the motor cover with a plurality of screws, securing the impeller to the lower end of the motor shaft, inverting the fan cover and securing it to the blower housing utilizing screws, placing the float ball in a depression of the fan cover, inverting the tank lid and securing same to the blower housing by means of screws. All of the above elements are assembled to one another without the necessity of lifting any of the elements once they are secured to the other elements.
