A solar panel cleaning system includes a brush connected by a hose to a fluid supply. The brush has scrubbing material, such as bristles, attached to a brush body for mechanically cleaning the surface of the solar panel. The width of the contact surface of the scrubbing material may be equal to the width of the solar panel, so that the solar panel may be cleaned with only upward and downward strokes. The brush body may further support a fluid manifold that receives the fluid from the fluid supply. The fluid manifold may include nozzles that emit the fluid under pressure onto the solar panel. The nozzles may project both frontward and rearward of the brush body so that the fluid sprays off the solar panel in front of and behind the brush. Spray patterns of the nozzles may overlap and impinge the entire width of the solar panel.

A hose accessory includes a handle, a shaft slidably received in the handle, and a flexible conduit located within handle and shaft. The flexible conduit may be arranged to carry fluids between a first end of the hose accessory and a second end of the hose accessory. A lock is provided to secure the shaft in a fixed position relative to the handle. The lock may include a locking pin biased towards a locked position. The shaft may include first and second channels. The first channel receives at least a portion of the locking pin when the locking pin is in a locked position. The conduit extends through the second channel that isolates and separates the conduit from the locking pin.

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.

A fluid dispenser having a liquid release bottle with suction bellows which is incorporated into a flat mop. This embodiment includes an exterior wall, an interior chamber surrounded by an exterior wall and a cap on the liquid intake member. The exterior wall includes a suction bellows to create a suction within the interior chamber of the liquid release bottle. A downward force on the handle activates a suction bellows to create a suction on the interior chamber of the liquid release bottle enabling fluid retained in the interior chamber to flow out of a duck-bill valve and into flexible tubing which will then flow through the tubing and out an opening of a yoke so that the fluid can flow onto a front of a scrubbing portion of the mop to facilitate cleaning. An alternative embodiment replaces the liquid release bottle with a liquid squeeze bottle.
