Provided is a self-propelled cleaning robot that can efficiently clean a flat surface even if a step is formed. The self-propelled cleaning robot that self-travels on a structure to clean a flat surface of the structure, the structure being installed in an outdoor location, the robot includes: a robot main body (2) in which a self-propelled moving mechanism (4) is provided; a cleaning unit (10) that is provided in a front portion and/or a rear portion of the robot main body (2); and a controller (30) that controls activation of the moving mechanism (4). At this point, the controller (30) includes an attitude controller (35) that detects an attitude of the robot main body (2), the attitude controller (35) includes a floating detection sensor (36) that detects floating in one of the front portion and the rear portion of the robot main body (2), and, when the floating detection sensor (36) detects the floating in one of the front portion and the rear portion of the robot main body (2), the controller (30) controls the activation of the moving mechanism (4) such that the cleaning unit (10) passes through a place where the floating is detected after the floating is eliminated.

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 remaining water suction device may include: a suction nozzle, a water separation chamber configured to be connected to a discharge port of the suction nozzle and provided with a water discharge port and an air discharge port, and a buffer tank configured to be connected to the water discharge port and store water separated from the water separation chamber. The remaining water suction device may include a water transfer pump configured to transfer the water stored in the buffer tank, a water storage tank configured to store the water transferred through the water transfer pump, a suction fan configured to provide a suction force to the air discharge port, and a suction motor configured to drive the suction fan.

An upright surface cleaning apparatus includes a surface cleaning head having a dirty air inlet. A support structure is moveably mounted to the surface cleaning head and a portable cleaning unit is removably mounted to the support structure. An above floor cleaning wand is provided.

A building cleaning apparatus includes a platform adapted to be suspended along a side of a building. The platform includes a base and a barrier mounted on the base that encloses an operator work station. The building cleaning apparatus includes a building cleaning structure mounted beneath the base of the platform. The building cleaning structure includes a cleaning component that is driven by a motor. The cleaning component is mounted such that at least a portion of the cleaning component is directly beneath the base of the platform during cleaning of the building.

A cleaning brush apparatus that is mountable onto a platform that is suitably suspended from a building for cleaning exterior and/or interior surfaces of the building. The cleaning brush apparatus includes a cleaning brush that is rotatable relative to the platform about a rotation axis that is parallel to the longitudinal axis of the platform. The cleaning brush apparatus is mounted to the platform in a manner to define a walkway on the platform to the rear of the rotation axis that permits a human operator to walk on the platform behind the rotation axis and along at least a length of the cleaning brush apparatus. The cleaning brush apparatus may also be adjustably mounted on the platform to permit the cleaning brush apparatus to be adjusted in position on and relative to the platform in a direction parallel to the longitudinal axis.
