ABSTRACT:
A multipurpose cleaning device, which utilizes water pressure to drive a rotary wheel which is heavier on one side and has teeth that slope in one direction. Elastic elements are provided to reinforce the vibration caused by the rotary wheel when the rotary wheel is forced to rotate by the water pressure. A control plate is set between a fixed wheel and a contact plate to control flow rate of water so as to regulate the strength of vibration. Different cleaning elements are adapted to be releasably attached to the device according to different cleaning purposes.
