  • Vacuum and disposal system for animal feces
    Patent number: 7003846
    Abstract: A vacuum and disposal system for the collection and disposal of animal feces. The vacuum and disposal system consists of a vacuum source, a vacuum tube, a flexible hose, and an intake tube. The vacuum is provided by an electric motor powered by a rechargeable battery and is used to create a vacuum or suction through the vacuum tube, the flexible hose, and the intake tube to collect the animal feces. A cartridge having a filter is inserted into the intake tube to receive the animal feces collected. After collection, the vacuum and disposal system is converted to an unload position for the removal of the cartridge from the intake tube and the ultimate disposal of the animal feces. Alternatively, a compact vacuum and disposal system may be used in smaller areas.
