A portable hard surface cleaning appliance includes a suction nozzle with a suction opening on which at least one drawing-off lip is arranged, a suction unit in flow connection with the suction nozzle for sucking up a liquid-air mixture from the suction opening, a separation chamber arranged between the suction nozzle and the suction unit and having a separation device arranged within for separating liquid from the liquid-air mixture, and a tank accommodating compartment in which a dirty liquid tank for receiving the separated liquid is releasably held. The tank accommodating compartment includes at least one supporting element engaged under a lower tank section of the dirty liquid tank, and at least one holding element releasably connectable to an upper tank section of the dirty liquid tank. The portable hard surface cleaning appliance includes two holding elements which receive between them the upper tank section of the dirty liquid tank.

A self-propelled device includes a body, a walking module, an air extraction module, an air pressure sensor and at least one bumper structure. The body is defined with a first space and a second space in communication with the first space, wherein the volume of the second space is smaller than the volume of the first space and the second space is closer to a side of the body than the first space. The walking module is adjacent to the body. The air extraction module is arranged on the body and is in communication with the first space. The air pressure sensor is arranged on the body and disposed at one end of the second space. The bumper structure is relatively movably arranged on the body, and is configured to close the second space when located at a first position and open the second space when located at a second position. The self-propelled device is for walking on a board surface.

A surface cleaning device including a surface-contacting assembly having a suction opening; a body; a suction source in fluid communication with the suction opening for sucking a fluid mixture of liquid and air from a surface; a rotation assembly mounted on the body for rotation relative to the body, the rotation assembly being rotationally fixed relative to the surface-contacting assembly, a separation chamber in which liquid is separated from the fluid mixture, the separation chamber providing a suction inlet in fluid communication with the suction opening, a suction outlet in fluid communication with the suction source, and a drainage outlet for connection to a receptacle for receiving liquid separated from the fluid mixture; and a receptacle for receiving liquid separated from the fluid mixture via the drainage outlet.

A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter and in an upper end of the hand vacuum cleaner. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner. The clean air outlet may be positioned below the suction motor and fan assembly whereby air may travel generally downwardly from the suction motor and fan assembly and through the post motor filter to the clean air outlet.

An electric window cleaning device includes an operating portion and a wiping portion which are attracted to both sides of a glass of a window by magnets, and are free to move along the glass by virtue of balls. The wiping portion includes a power mechanism and a power supply device. The power mechanism includes an output shaft, a rotary disc and a duster removably fixed to the rotary disc. The power device includes a switch and a battery which are electrically connected to the power mechanism. When the power mechanism is turned on, the output shaft rotates the rotary disc and the duster to clean the outer surface of the glass, as an user moves the operating portion which is attracted to the inner surface of the glass, the wiping portion will also move along the outer surface of the glass to perform cleaning operation.
