发明名称 VACUUM CLEANER NOZZLE HAVING ROTATING BRUSH
摘要 <p>SV-60 VACUUM CLEANER NOZZLE HAVING ROTATING BRUSH 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.</p>
