Abstract:
A cleaning attachment to water hose is provided comprising an outer shell having a dome-shaped base skirt including a connector member for tightening the flared top end of the neck section of the outer shell to the water hose in a sealing engagement, a main ball valve to permit passage of water and out of alignment therefrom to block the entire water stream; and a water chute with two extensions each extending approximately in parallel with the interior walls of the outer shell and in a first spiral form. A dome-shaped outer rotor with a number of fans and a bottom brush is rotationally positioned in the base skirt under the water chute for receiving the pressurized impacts of the water streams to activate the outer rotor in a first direction.
