Abstract

Water flow-driven rotary and vibrational cleaning brush including a base seat, a water wheel, a brush seat and a transmission unit. The base seat is a receptacle having an opening facing downward. An outer and an inner faces of the base seat are respectively formed with a fluid inlet and a nozzle. The water wheel is disposed in the base seat and rotatable about a shaft rod. The water wheel is impacted and rotated by the fluid injected by the nozzle. The brush seat is positioned under the base seat. A brush section is disposed under the brush seat. The transmission unit is disposed between the brush seat and the water wheel and includes a transmissions section connected with the brush seat for transmitting the rotational power of the water wheel to drive the brush seat.
