WET/DRY VACUUM CLEANER AND FILTER THEREFOR

摘要

A vacuum cleaner for both wet and dry operations includes a debris canister within which a cyclonic suction / exhaust flow that carries vacuumed debris may be established, a vacuum fan and motor housing, a vacuum fan and motor assembly mounted substantially within the housing, and an inverted conical filter. The filter is pre-formed from a self-supporting, porous material for filtering debris carried by the suction / exhaust flow and also permits the passage of water. It may have the configuration of a truncated cone. The vacuum cleaner may also include a valve assembly positioned to limit the accumulation of liquid debris within the debris canister to a threshold level.
