Abstract
A vacuum cleaner that has a rotary floor agitator driven by a motor has a hair cutter blade mounted adjacent a motor shaft that drives the agitator and/or at the ends of the agitator. The agitator is driven by an electric motor through a drive belt. The cutter blade(s) are designed to sever elongate particles, such as hair or threads that would build up on the agitation brush, drive belt and motor output shaft to hinder the operation of the brush and belt or otherwise dislodged the belt from the motor shaft.
