A dual brush is disclosed having a handle and housing substructure for storing and dispensing cleaning solution. A flexible overmold forms a diaphragm pump to expel cleaning solution through a dispensing valve and port located between a removable brush head and a removable pad head. The removable brush and removable pad head are removably attached to the handle and housing substructure with a tab and slot arrangement, and are attached at an angle that facilitates ease of use at an optimal cleaning orientation.

The invention relates to an apparatus for cleaning surfaces, in particular of solar collectors and/or of photovoltaic installations, having at least one cleaning member, in particular a brush roller or plate brush, moving, in particular rotating, during the cleaning operation, having a holding device for the cleaning member, having a fluid drive for the cleaning member operable in different states and having a switching device with which a change can be made between the different operating states of the fluid drive.

A substrate cleaning apparatus for performing scrub cleaning of a surface of a substrate by rotating both of the substrate and a roll cleaning member while keeping the roll cleaning member in contact with the surface. The apparatus includes a roll holder configured to support and rotate a roll cleaning member, a vertical movement mechanism, having a vertically movable unit vertically movable by actuating an actuator having a regulating device, configured to vertically move the roll holder coupled to the vertically movable unit so the roll cleaning member applies a roll load to the substrate W while cleaning the substrate. A load cell provided between the vertically movable unit of the vertical movement mechanism and the roll holder is configured to measure the roll load. A controller is configured to perform feedback control of the roll load through the regulating device based on a measured value of the load cell.

A charging compartment adapted for use on a body of a photovoltaic panel cleaning equipment for recharging of battery power of the photovoltaic panel cleaning equipment is provided, in which the charging compartment includes a charging and stopping rack and a telescopic supporting rack. The charging and stopping rack is used for stopping a body and charging the body, and the telescopic supporting rack is used for supporting the charging and stopping rack. The charging and stopping rack and a photovoltaic panel to be cleaned are enabled and configured to be on a same plane by adjusting the angle of the charging and stopping rack. By adopting the charging compartment, the photovoltaic panel cleaning equipment is facilitated to allow the body to remain stationary while being together with the photovoltaic panels which are undergoing cleaning, as well as same time recharging battery power of the photovoltaic panel cleaning equipment.

A self-charging terminal, which includes a terminal fixing block, a sloped conductive member and a sloped conductive member mounting member is disclosed. The self-charging terminal is adapted for a photovoltaic panel cleaning equipment for facilitating recharging of battery power. The sloped conductive member is fixed on the sloped conductive member mounting member and the sloped conductive member mounting member is fixed on the terminal fixing block. The self-charging terminal is detachably mounted on the photovoltaic panel cleaning equipment and a shape of the sloped conductive member of the self-charging terminal is specifically matched with that of a telescopic charging member of photovoltaic panel cleaning equipment to facilitate wipe off an oxidization layer on the sloped conductive member, thereby prolonging service life of the self-charging terminal and extending repair cycle time. A photovoltaic panel cleaning equipment including the self-charging terminal mounted on a charging compartment thereof is also disclosed.

An automatic washing apparatus for dogs and alike animals comprises a washing tub, a brushing plate and a horizontally moving carrier board on each side of the tub. Each brushing plate is attached to a vertically moving crank slider through horizontal extension arms. Each crank slider is motorized by a motor and situated on a carrier board. In other embodiments the brush plates are driven by other mechanical mechanisms such as Scotch Yoke, Whitworth quick return, cam slider, reciprocating gear rack or rotation to rotation mechanisms using gears or pulleys and belts. The carrier boards are mobilized through pulley and belt, and wheels on rails. The movement is guided by a guiding rail. The tub includes a door and a drain on the floor and a waste water compartment beneath the floor. The brushing plates and carrier boards are enclosed under two side covers. The apparatus further provides a water spraying system including spraying tubings, a water tank and a water pump.

A long rod cleaning machine having an electric motor, a tip tool including a cleaning portion, a head to which the tip tool is attachable, a rod, and a rotator between the head and the rod. The tip tool is attached in a manner movable with a driving force from the electric motor. The head includes a peripheral portion surrounding the cleaning portion and including a surface-cleaning lateral portion to be in contact with a cleaning target surface together with the cleaning portion. The rotator includes a rotation restrictor connecting the head to the rod in a manner rotatable relative to the rod about at least two axes. The rotation restrictor partially or fully restricts rotation of the head.

A pet hair removal apparatus has a plurality of engagement members. The apparatus has a handle and connected base member. On the base member is one or more engagement members, such as lugs, protrusions or frustums. On the lower surface of one of the engagement members is one or more striations, ribs, squeegees or ridges. The striations, ribs, squeegees or ridges operate in an operational engagement position to remove pet hair from the surface of an inanimate object, such as a couch or other fabric. This operational engagement position for the striations, ribs, squeegees or ridges is one of a number of other operational engagement positions for the pet hair removal apparatus.
