A self-moving cleaning device includes: a base; a mobile module adjacent to the base and configured to contact a surface when the self-moving cleaning device moves on the surface; a vacuum module arranged over the base; a dust box arranged over the base and connected to the vacuum module, the dust box including a first opening and a second opening; a first suction port arranged on the base and including a first suction inlet connected to the first opening; a second suction port arranged on the base and including a second suction inlet connected to the second opening, the first suction port disposed between a front side of the base and the second suction port; a roller brush device arranged on the base and within the second suction port; and an air duct, wherein the first suction port is connected to the dust box through the air duct to thereby connect the first suction inlet to the first opening.

The present disclosure relates to the field of smart home technology and proposes a base station and a cleaning robot system. A base station applicable to clean a cleaning mechanism of a cleaning robot includes a cleaning tank, configured to accommodate at least part of the cleaning mechanism and clean the at least part of the cleaning mechanism, the cleaning tank includes a first end face and a second end face, a direction of a connection line between the first end face and the second end face is substantially parallel to an extension direction of the cleaning mechanism. A cleaning robot system is further provided.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, and a controller for controlling the operation of the autonomous floor cleaner. The drive system can include at least one drive wheel for driving the housing across a surface to be cleaned. The drive wheel can be selectively moved from an engaged or in-use position to a disengaged or maintenance position. In the disengaged or maintenance position, the wheel is disengaged from the autonomously moveable housing such that it can be pivoted, extended, removed, or otherwise moved farther away from the autonomously moveable housing.

A robot cleaner includes a main body, a water tank including a turbidity sensor and a water level sensor, and a pair of rotary mops configured to move the main body while rotating in contact with a floor. A drive motor rotates the pair of rotary mops and a nozzle supplies water from the water tank to the rotary mop. A rotary mop controller varies an output current of the drive motor based on signals from the water tank sensors. A controller determines whether the water tank is contaminated based on the output current of the drive motor received from the rotary mop controller.

A robot cleaner includes a main body forming an exterior and having a water tank housing formed at a rear side thereof. The water tank housing may form a space in which a water tank is mounted. At least one spin mop is rotatably provided at a lower side of the main body, moving the main body by rotating, and configured to clean a floor using water in the water tank. A supply nozzle is provided at one side of the water tank housing, and when connected to a discharge nozzle of the water tank, communicates with the discharge nozzle to supply water stored in the water tank to each of the spin mops. The robot cleaner further includes a locking device rotatably provided at a position spaced apart from a circumferential surface of the water tank housing, and configured to secure the water tank in the water tank housing when mounted or to release the water tank by pushing backward on the water tank.

A surface cleaning machine includes: a suction device; a cleaning base suitable for moving on a surface to be cleaned, the cleaning base comprising a cleaning roller capable of rotating; a cleaning liquid supply unit; and a dirty liquid recovery tank, the dirty liquid recovery tank being in fluid communication with the suction device; where the cleaning base further includes a transfer chamber adjacent to the rear side of the cleaning roller and capable of temporarily holding a solid-liquid mixture, the transfer chamber configured to be in fluid communication with the suction device, so that the surface cleaning machine can transfer at least a part of liquid or at least a part of a solid-liquid mixture from the transfer chamber to the dirty liquid recovery tank by means of the suction device, thereby achieving a low energy consumption operation.

A surface cleaning apparatus adapted for wet cleaning includes a heated fluid delivery system having a dual-phase distributor that dispenses heated liquid and steam vapor. The dual-phase distributor can include a phase separator that separates a vapor phase of a heated fluid from a liquid phase of the heated fluid, a heated liquid outlet, and a steam vapor outlet. The apparatus can further include a liquid delivery system, and/or a recovery system.

The present disclosure provides a surface cleaning apparatus that includes steam delivery. The apparatus includes a hand-carried body adapted to be hand carried by a user, the hand-carried body having a main housing, a supply tank, and a heater. A flexible hose is mounted to the hand-carried body and a hand-held cleaning tool mounted to an end of the hose. The tool has a liquid distributor to deliver liquid cleaning fluid and a steam distributor to deliver steam. Various features for controlling the operation of electrical component of the extraction cleaner are disclosed.

A method of operating an autonomous cleaning robot includes presenting, on a display of a mobile device, a representation of each of multiple cleaning levels, each cleaning level corresponding to a respective rank overlap parameter for a wet cleaning mission of the autonomous cleaning robot. The method includes receiving, at the mobile device, an input indicative of a selection of one of the cleaning levels; and controlling the autonomous cleaning robot to execute a wet cleaning mission according to the rank overlap parameter corresponding to the selected one of the cleaning levels.

A surface cleaning apparatus having a housing, a suction nozzle, a suction source, a steam port, a steam supply system, and a flexible seal. The housing having a cleaning foot and an upper housing operably coupled to the cleaning foot. The suction source being fluidly connected to the suction nozzle by a working air conduit. The steam port having an aperture provided in the cleaning foot. The steam supply system having a steam nozzle with at least a portion that projects through the steam port. The flexible seal being provided at least around the steam nozzle.
