  • Patent number: 6189174
    Abstract: Floor care apparatus is disclosed wherein a powered brush assembly having a multiplicity of rotary brushes is suspended within the apparatus such that the brush assembly floats freely upon the surface being cleaned without supporting any of the machine's weight. The rotary brushes are generally configured as spur gears and function in a gear train wherein one brush drives all other gear brushes in the system. Axially projecting brush bristles are embedded in each gear tooth such that there is no unbrushed area between adjacent brushes in the brush line. The portion of the gear tooth wherein the bristles are embedded includes a recessed profile to allow for circumferential expansion of the tooth, upon insertion of the brush bristles, thereby preventing gear tooth interference. The brush assembly is particularly suitable for hot water carpet extractors of the upright design.
