A planar surface cleaning system including a main body, at least one vacuum source, and a cleaning component is disclosed. The main body includes a bottom portion, wherein the bottom portion defines an outer portion defining a surface area about a perimeter thereof and an inner portion defining a cavity formed within the outer portion. The at least one vacuum source is supported by the main body and is in fluid communication with the cavity. The cleaning component covers the surface area defined on the outer portion and is removably connected to the outer portion. The planar surface cleaning system further includes a handle portion. The handle portion may be connected to the main body via a U portion.

An unmanned cleaning apparatus for cleaning structures such as buildings, more specifically windows on buildings includes a carriage, a cleaning element rotatably mounted on the carriage, at least a pair of support arms, at least a pair of electric ducted fans, a motor that in use is operable remotely to rotate the cleaning element about its horizontal axis across the surface to be cleaned, and a spray boom that is mounted on the carriage. A cleaning system includes the unmanned cleaning apparatus as described and a portable winching member.

A cleaning apparatus (100) comprises a cleaning base (1) having a brush roll (12), a cleaning fluid dispenser (14), a suction nozzle (13), and a brush-roll motor, a lower portion (21) of a manipulating shaft (2) pivotally coupled to the cleaning base (1), a portable cleaner body (3) removably mounted to the manipulating shaft (2), and a suction extension hose (4) capable of being adapted for use with the portable cleaner body (3). The portable cleaner body (3) is selectively engaged with the manipulating shaft (2) or the suction extension hose (4) to obtain a plurality of modes of operation.

A roof cleaning system for removing snow from a roof includes a crane that has a boom and a man box that is coupled to the boom. The crane positions the man box above a roof of a building. A sweeper is coupled to the man box and the sweeper sweeps snow from the roof. The sweeper is operationally coupled to the crane.

A system and method for cleaning a collector surface of a solar collector. The system includes a first liquid-dispensing unit configured to deliver a first spray of liquid to the collector surface. The system also includes a brush element having a longitudinal side oriented along a first direction and disposed adjacent to the first liquid-dispensing unit. A first squeegee element is oriented along the first direction and adjacent to the brush element. The first squeegee element, the brush element, and the first liquid-dispensing unit define a first cleaning area. A second squeegee element is oriented along the first direction and separated from the first squeegee element by a gap to define a second cleaning area. The system also includes a second liquid-dispensing unit configured to deliver a second spray of liquid to the second cleaning area located between the first and second squeegees.

A floor cleaning tool includes a housing that retains a motor for driving a pair of scrubbers configured for rotational motion for contacting the floor below the frame. A baseboard scrubbing assembly is mounted at the front of the housing in a vertical orientation perpendicular to the floor. A baseboard pad simultaneously contacts the baseboard adjacent the floor as the scrubbers are moved across the floor.
