Реферат: VACUUM CLEANER NOZZLE HAVING ROTATING BRUSH ABSTRACT OF THE DISCLOSURE 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 addi-tional 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 direc-tion. The latter agitates the carpet or other floor cover-ing to loosen and direct dirt particles toward the inlet slot of the vacuum cleaner nozzle.
