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 portable foam brush assembly having a base having a soap supply, a water supply, and an electrical supply. A foam brush wand is detachably dockable to the base and in electrical and fluid communication with the foam brush wand having battery pack, a peristaltic pump, a reservoir chamber, a foaming chamber, an air pump, a brush and a momentary release switch. The base water supply and the base soap supply, when activated, are configured to travel by a water supply hose and a soap supply hose to a tee in the base where they are combined in a combined hose to a base quick coupler that is connectable to a reciprocal foam brush wand quick coupler, which has a foam brush wand hose to deliver the water soap mixture to bladder in the foam brush wand.

A toothbrush is provided. The toothbrush may include a brush head having a first brush and a second brush. Each of the first brush and second brush may include bristles extending radially from first ends of the first brush and second brush. The first brush and second brush may rotate in opposite directions along rotational axes parallel to a longitudinal axis of the toothbrush to brush away from the gums of a user and assist with implementing a rolling brushing method.

A cleaning mechanism having a self-locking function, comprising a cleaning rack, a cleaning member and a sweeping member, adapted for use on photovoltaic panel, is disclosed. The cleaning rack comprising a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod which are detachably connected. The cleaning member being detachably mounted between the first connecting rod and the third connecting rod, used for stripping off adhesive materials on photovoltaic panel; the sweeping member used for sweeping adhesive materials away from photovoltaic panel. Cleaning mechanism further comprises a cleaning member power unit, detachably connected with the cleaning member and used for driving cleaning member to rotate; and cleaning member power unit comprises a self-locking device, used for preventing cleaning member from idling, and sundries are prevented from being twisted thereon and meanwhile unnecessary wear between cleaning member and photovoltaic panel can be reduced.

One or more oral care implements are described. The oral care implement includes an outer member, an inner member positioned within at least a portion of the outer member, and a cleaning element extending from the outer member. Also provided herein are one or more related methods.
