  • Patent number: 6419169
    Abstract: A portable compact extractor having permanent solution and recovery tanks integrally formed in a single main tank portion, with a removable power head attached to the top of the main tank. A fill port passes through the powerhead into the cleaning solution tank and a pour spout is formed in the recovery tank. With this construction, the cleaning solution tank may be filled with water and, if desired, detergent, by pouring the water and detergent into the fill port in the power head, and the recovery tank may be emptied as desired simply by tipping the unit and pouring the contents of the recovery tank out the pour spout and down the drain, without ever having to remove any tanks, bottles or the power head from the unit, or disconnect and reconnect any tubes. A carry handle is located on the powerhead to facilitate transportation of the unit, removal of the power head from the main tank for cleaning the tanks when desired, and to facilitate pouring the contents of the recovery tank out of the pour spout.

  • Patent number: 5961676
    Abstract: 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.
