摘要： A vacuum cleaner includes an internal electrical supply cord and a control cable. These two elements are secured to a suction duct for mounting and guidance. The control cable also extends arcuately, smoothly around a lower motor-fan housing section to limit wear and kinking.

摘要： 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.

摘要： A floor cleaning unit having a housing and a removable caddy which may be mounted on and removed from the housing for storing accessories. The caddy includes a body which removably mounts to the housing. A connector assembly is included on the body for removably mounting the body on the housing. The connector assembly includes a slot for receiving a hook member attached to the housing. An accessory retainer is formed on the body for storing the floor cleaning unit accessories, whereby the caddy and the floor cleaning unit accessories stored thereon may be slidably removed from the floor cleaning unit by merely applying a force to the body.
