ABSTRACT:
A vacuum floor cleaning system is provided having a carpet fiber agitating brush which oscillates in a plane horizontal to the floor. The vacuum floor cleaning system of the present invention includes generally a base member supported above the floor by wheels. The base member defines a nozzle opening positioned in close proximity to the floor and an air flow path between the nozzle and a dirt accumulation container. The base member serves as a mounting container for an electric motor, a suction producing fan, and a carpet fiber agitating brush bar.
The electric motor is mounted to a motor baseplate in the base member and drives a rotating motor shaft which protrudes from a motor housing. The suction fan is mechanically coupled to and rotatably driven by the motor shaft to produce an air flow along the air flow path from the floor to the dirt accumulation container. A carpet fiber agitating brush bar including a plurality of brush bristles positioned within the nozzle opening is moveably supported in the base member by an agitator suspension member and is coupled to the motor shaft by an agitation transmission comprising a transmission disc having a brush bar drive shaft mounted eccentrically with respect to the motor shaft. The motor shaft drives the agitation transmission to impart limited eccentric movement to the carpet agitating brush bar within a plane parallel to the floor.
