ABSTRACT:
A vacuum cleaner having a retractable sweeper strip brush positioned within the nozzle behind the rotating agitator brush. A pinion is mounted on one end of the brush housing axle and meshes with a rack slidable in a housing in the chassis behind the nozzle. One end of the rack is connected to a connecting link having the other end eccentrically connected to a lever pivotally mounted at the rear of the cleaner chassis. The lever includes a tab which protrudes through a slot in the chassis for turning the lever to thereby pivot the brush to extend the bristles downwardly from the nozzle when cleaning bare floors and to retract the brush when cleaning carpets or the like.
