Zusammenfassung:	A hard bag cleaner door is disclosed having air directing rib vanes integral with its inner surface. These vanes take the form of, alternately, angled J-shaped ribs and short straight interleaved ribs. All the ribs are stepped so that the flow passage for air moving along the interior side of the bag door diverges as more bag air is introduced to it so that it directs efficiently air flow to a lower disposed motor-fan section of an adjoining hard bag portion.
