  • Patent number: 11033001
    Abstract: An automatic wet washing and dry brushing apparatus for dogs comprises an elongated container, a tub placed inside the container at one end, a movable brush panel on each side of the tub and a mechanical device that drives the brush panels. The mechanical device is installed in the space between the container walls and the tub walls. The tub has two sidewalls, a floor with a drain, and a door at one end. Each brush panel is suspended on a sidewall and supported by a rail affixed inside the sidewall through a slot on the sidewall. The brush panels are used to brush a dog by sliding in a reciprocating motion. The brushes are made of spaced long and flexible bristles that accommodate the dog's body shape. The tub is equipped with water sprayers and a drain system. The container is movable with 4 wheels.

  • Patent number: 10405518
    Abstract: An automatic washing apparatus for dogs and alike animals comprises a washing tub, a brushing plate and a horizontally movable carrier board on each side of the tub. Each brushing plate is attached to a vertically movable crank slider through horizontal extension arms. Each crank slider is motorized by a motor and situated on a carrier board. The carrier boards are mobilized by a low speed motor through pulleys, a timing belt, and wheels on rails. The movement is guided by a guiding rail. The tub includes a door and a drain on the floor and a wastewater compartment beneath the floor. The brushing plates and carrier boards are enclosed under two side covers. The apparatus further provides a water spraying system including spraying tubings, a water tank and a water pump.
