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. In a second embodiment, an exhaust opening is formed in the hard bag cleaner door below the air directing rib vanes and is covered by a final filter and final filter door. The air moving along the interior side of the bag door is directed out the exhaust opening, through the final filter which filters small dust particles which may be present in the exhaust air and out vent openings formed in the final filter door.
