ABSTRACT:
An apparatus cleans footwear with a closed system utilizing brushes and with recirculating compressed air. The apparatus has a housing and a cover containing a grill mounted to the housing by springs. Beneath the grill are a pair of cylindrical brushes which are rotated by electric motors in a direction toward the center of the grill. A combined vacuum cleaner and air compressor beneath the grill provides both a source of compressed air to help clean the shoes and suction to collect the dirt and any other debris dislodged by the apparatus. The brushes clean the bottoms of the shoes and direct any dislodged dirt and other debris toward the center area of the grill. A pair of air tubes disposed along the edges of the grill direct the compressed air over the shoes and toward the center of the grill, along with any debris dislodged thereby. Beneath the center of the grill is a removable collection tank having a slot facing the grill and having an open end connected by a filter to the intake of the air compressor. The air compressor draws air into the tank through the slot and draws any debris in the collection area into the tank. The debris is removed from the air by the filter and the filtered air is then recompressed and recirculated via the air tubes over the top of the shoes.
