  • Patent number: 5957090
    Abstract: A device for removing dirt, loose hair, dander, etc. from objects such as household pets comprising an electrostatic generator 12 connected to an electrostatic element 10. The electrostatic element is a high voltage capacitor with extended core dielectric 10C. If an object such as a pet is brought in close proximity to its surface the electrostatic force pulls dirt and loose hairs off and retains them. A discharge means 12A provides for the release of the collected dirt and loose hairs. When incorporated into a grooming device such as a brush 18 it provides a more efficient method for removing loose hairs.
