  • Self cleaning chair for barber shops and beauty shops
    Patent number: 3994528
    Abstract: A barber and beauty salon chair which is of the usual appearance with a hydraulic or other lift to regulate the height of the patron, but which is self cleaning, as it contains a vacuum suction pump in the base with suction pipes opening onto the floor for suctioning in hair cuttings, and other debris. There is a switch on the chair for turning the suction pump on when the patron is finished, and this causes all the hair cuttings and the like to be suctioned off the floor and into a receptacle inside the base to be emptied out later.
