  • Patent number: 5826300
    Abstract: A multi-purpose vacuum cleaner accessory is provided for use in grooming multiple types of animals and for cleaning fabric and flooring substrates. The accessory comprises a body and a brush attachable thereto. The brush is configured for creating an airflow directed to the surface of the animal's coat or substrate so that the brush is effective for use on all types of animal coats and fabrics/flooring. The brush comprises a circumferential, downwardly-extending skirt and a plurality of cross-members extending inwardly from sides of said brush and joining together in the interior thereof. The skirt and cross-members have a plurality of downwardly-projecting, spaced teeth wherein the teeth are comprised of a thermoplastic material having a relatively high co-efficient of friction to adhere to loose hair to be suctioned (preferably, a durometer reading of Shore A65) and sufficient strength for said brush to achieve brushing action.

  • Patent number: 5768747
    Abstract: A two-component vacuum cleaner accessory for the dual purpose of grooming animals and removing hair and debris from fabric such as that used for upholstery. The body of the accessory has a back and sides and attaches to a circumferential brush which has a skirt and cross-members with downwardly-projecting flexible triangular teeth. Flanges on the brush fit into recesses on the body and serve as handgrips for a user. Pressure drop across the device is controlled by the crosspiece and the design and length of the triangular teeth. The use of soft elastomeric triangular teeth having a high co-efficient of friction provides efficient removal of hair and debris.
