    Abstract: A power mop is provided having a tank for holding a liquid positioned for gravity-induced flow of the liquid from a gravity feed conduit into a hand grip. Inside of the hand grip is a liquid inlet, a valve for controlling the flow of the liquid, a pump for providing flow pressure to the liquid, and a battery for powering the pump. Additionally, a switch is accessible external to the hand grip for powering the pump and switching the valve between open and closed liquid flow positions. A handle tube is connected to the hand grip. The handle tube contains a pressure feed conduit for receiving pressurized flow of the liquid from the hand grip. A nozzle is mounted on the handle tube to disperse the liquid onto the surface to be mopped. A mop head is attached to the end of the handle tube remote from the hand grip.
