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.

A cleaning device includes a rolling brush mounted on a housing and can be in rolling contact with the ground. A waste collection region is integrally or separately provided in the housing, and the waste collection region is provided with a collection inlet provided corresponding to the rolling brush. Waste brought up by the rolling contact is collected into the waste collection region under the rotation action of the rolling brush. The housing is provided with one or more scraping guiders connected to the collection inlet, and each of the scraping guiders is in flexible pressure contact with the rolling brush or the ground, and is configured to scrape off residual waste absorbed by the rolling brush or residual waste on the ground and transfer the residual waste into the waste collection region.

Provided is a robot cleaner in which a liquid may be uniformly supplied to a plurality of cleaners and which is easily inspected and repaired in case of defects such as water leakage. The robot cleaner includes a main body portion; a plurality of cleaner fixing portions provided at a lower portion of the main body portion, a plurality of cleaners for wet cleaning being fixed to the plurality of cleaner fixing portions, respectively; a liquid supply portion provided in the main body portion and storing a liquid and supplying the stored liquid to at least one of the plurality of cleaners; a liquid distribution member provided at a lower portion of the main body portion and directly supplying the stored liquid to at least one cleaner of the plurality of cleaners; and a flow path portion providing a movement path of the liquid from the liquid supply portion to the liquid distribution member.

A cleaner includes a body, a left spin-mop module and a right spin-mop module configured to perform mopping, and a water supply module configured to supply water to the left spin-mop module and the right spin-mop module. The water supply module includes a water tank to store water therein, a pump to pressurize the water in the water tank to move the water to the left spin-mop module and the right spin-mop module, a first supply pipe connecting the water tank and the pump, a common pipe connected to the pump, the common pump configured to guide movement of the pressurized water from the pump, a first branch pipe configured to guide a first portion of the water in the common pipe to the left spin-mop module, and a second branch pipe configured to guide a second portion of the water in the common pipe to the right spin-mop module.

A mop includes a floor cleaning portion, an upper absorbing portion located over the floor cleaning portion, the upper absorbing portion being configured to receive water supplied from a water tank to supply the water to the floor cleaning portion, and an attaching portion located over the floor cleaning portion, the attaching portion being connected to the upper absorbing portion. At least a portion of the attaching portion is located to overlap an outer edge of the upper absorbing portion in a vertical direction.

A robot cleaner is disclosed, which comprises a main body forming an external appearance, a water bucket unit provided in the main body, supplying water to a water mop, a driving wheel rotated by a rotational force of a driving motor provided in the main body, moving the main body, and a wiper module provided in the water bucket unit, wherein the wiper module is extended to front and rear directions of the driving wheel and formed to be protruded toward the floor where the main body drives.

An automatic floor-disinfection robot for floors of hospital rooms, including a moving device, a alarm and a disinfection device. The moving device is a disc-shaped robot, and includes a chassis moving mechanism, a support plate and a top plate arranged successively from bottom to top. The disinfection device includes a disinfection assembly and a baffle. The disinfection assembly includes a liquid supply mechanism, a liquid spray mechanism and a fan.

A surface cleaning apparatus, such as a carpet extractor, includes a base and a fluid recovery system for drawing dirty cleaning fluid from a surface to be cleaned. The fluid recovery system includes a suction nozzle in fluid communication with a recovery chamber. The suction nozzle is mounted to the base for vertical movement with respect to the base and is biased into contact with the surface to be cleaned.

A robot cleaner includes a main body which forms an external shape; two or more spin mops which rotate in a clockwise or counterclockwise direction when viewed from above and mop a floor with a damp cloth, and move the main body; and a cleaning module which is positioned in front of the spin mops and collects foreign substance existing on a cleaning target surface, wherein the cleaning module includes: a housing which is coupled to the main body and opened at a lower side; a dust container which forms a space for accommodating foreign substance and is positioned to be detachable in a lower side direction of the housing; and an agitator which is positioned inside the housing, and sends foreign substance existing on the cleaning target surface to the dust container by a rotation operation.

Disclosed are a base station and a cleaning system. The base station is configured for pumping dirt from a cleaning robot and injecting water to the cleaning robot, and the cleaning robot is defined with a host dirt collecting chamber and a host clean water chamber. The base station includes a base station body, a dirt pumping assembly and a water injection assembly. The dirt pumping assembly is arranged in the base station body, and can move relative to the base station body and communicate with the host dirt collecting chamber; The water injection assembly is arranged in the base station body, and can move relative to the base station body and communicate with the host clean water chamber. The technical solution of the present application can make the use function of the base station more diversified, and improve the practicability of the base station.
