Abstract: A battery-powered, upright vacuum sweeper comprises a base assembly and a handle pivotably attached thereto. The base assembly comprises a vacuum fan assembly fluidly communicating with an inlet for vacuuming dust and the debris particles from a surface into a removable reservoir. A rotating roller brush attached to the base assembly sweeps the particles into the inlet. A dust pad assembly comprises a disposable dust cloth extending over a portion of the base assembly in contact with the surface to be cleaned for removing dust particles which are not removed by vacuuming.

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.
