Provided is a robot cleaner including a main body for forming an exterior of the robot cleaner, a driver for moving the main body, a cleaning module housing coupled to the main body, and a mopping unit accommodated in a space defined in the cleaning module housing to mop a traveling face, wherein the mopping unit includes a body disposed in the cleaning module housing, a plurality of mopping rollers arranged on the body, and a mop disposed to surround the body and the plurality of mopping rollers and in a surface contact with the traveling face. An area in contact with the traveling face is increased, so that a cleaning efficiency may be maximized.

A floor cleaner includes a recovery tank including an inflow path allowing liquid-laden air to enter the recovery tank, an outflow path allowing air to exit the recovery tank; and a chamber for storing liquid. The chamber includes an inlet, a separator that separates liquid from the liquid-laden air, an air outlet, and a float. The float includes a base and a valve with an indicator. The float is moveable between a first position and a second position. In the first position the valve is spaced away from the air outlet and air is allowed to exit the chamber. In the second position the valve is adjacent the outlet and impedes air from exiting the chamber. In the second position the indicator is visible when the chamber is full.

Embodiments of the present disclosure provide a self-cleaning control method of a cleaning device, a cleaning device, and a storage medium. The cleaning device is provided with at least one self-cleaning object. The control method includes: determining a current self-cleaning mode of the cleaning device according to a predetermined condition; and controlling the cleaning device to clean the self-cleaning object according to the determined current self-cleaning mode. Based on technical solutions in the embodiments of the present disclosure, different self-cleaning modes can be selected according to different dirt conditions of the cleaning device, thereby improving the selection flexibility of a self-cleaning mode of the cleaning device.

A portable cleaner has a recovery tank, including a container for receiving and storing recovered liquid and/or dirt and an openable tank lid for covering the container. The container and the tank lid are removable from the cleaner as a unit. The portable cleaner also has a main housing configured to removably support the recovery tank in a vertical orientation in which the tank lid at least partially defines a top side of the portable cleaner. In addition, a tank latch is provided in the tank lid, the tank latch configured to selectively secure and release the tank lid to the main housing when the recovery tank is supported by the main housing.

A surface cleaning apparatus includes a housing having a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. Various motor cooling arrangements are disclosed. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft floor surfaces.

A floor cleaning machine including a handle that pivots relative to a base about a pivot axis. A recovery tank is coupled to the handle in fluid communication with a suction motor assembly to receive and store fluid and dirt drawn through a suction nozzle. The floor cleaning machine further includes an expandable hose fluidly communicating the recovery tank and the suction nozzle. The hose is in an expanded configuration when the handle is pivoted about the pivot axis to a reclined position. The hose is in a retracted configuration when the handle is pivoted about the pivot axis to a substantially upright position. The hose at least partially wraps around the pivot axis with the pivot axis being between a portion of the hose wrapped around the pivot axis and the surface being cleaned in the expanded and the retracted configurations.

A wet surface cleaner operable in an upright cleaning mode, an auxiliary cleaning mode, and a lift-off cleaning mode. The surface cleaner has a canister assembly that is coupled to a body in the upright cleaning mode and removed from the body in the auxiliary cleaning mode and the lift-off cleaning mode.

A cleaning device designed to clean a surface includes a cleaner nozzle to face the surface to be cleaned and to perform a cleaning action on the surface, where the cleaner nozzle accommodates at least one rotatably arranged brush including flexible brush elements having tip portions which are intended to contact the surface. The cleaning device includes a force-actuable mechanism that is responsive to a change of a user force on the cleaning device acting to press the cleaner nozzle against the surface when the cleaner nozzle is in an operational position on the surface, and that is functional to cause a change of a value of at least one parameter of operation of the cleaning device, thereby enabling more intuitive handling of the cleaning device by a user.
