Abstract
A floor care appliance having a main housing with a handle extending from an upper portion thereof, and having a motor blower assembly affixed thereto with an inlet tube extending from a lower portion thereof. The main housing is fashioned with a rearwardly open cavity portion for receiving a filter arrangement including a paper filter bag having connection to an outlet tube of the motor blower assembly, and a second stage of filtration implemented by an air permeable closure covering the rearwardly open cavity portion. A floor unit carries a brush actuated by a reversible motor, a dry chemical carpet cleaning powder receptacle and dispensing arrangement for selectively dispensing the powder adjacent the brush, and a plenum chamber extending from adjacent the brush to a swivel having an outlet tube connected and affixed to the inlet tube of the motor blower assembly. A switch assembly is carried by a cover for the main housing and provides for operator selection of one of several modes of operation. A switch device is also provided to selectively actuate the dispensing arrangement during a specific one of the several modes.
