The present disclosure relates to the field of cleaning robot technology, and in particular to a cleaning robot system. The cleaning robot system includes a base station and a cleaning robot. The base station is independent to the cleaning robot of the cleaning robot system. The base station includes a base station body and a mop member cleaning device arranged on the base station body. The mop member cleaning device is configured to clean a mop member of the cleaning robot. Based on the base station, the cleaning robot system is capable of automatically cleaning the mop member with no need for users to change or clean the mop member frequently, which is helpful to free consumers from house cleaning, thus relieving the burden on the consumers, and also helpful to clean the mop member in time so as to ensure a better effect in next cleaning.

A floor mopping machine includes a casing and a motor. A partition plate is arranged at a middle of the casing, and a battery is arranged at a side of the partition plate. A first support roller is provided at an end of the battery away from the motor, and a second support roller is provided at an end of the first support roller away from the battery. A set of second pressure rollers are arranged between the first support roller and the second support roller, and a set of third pressure rollers are arranged between the first support roller and a driving roller.

A joint for floor cleaning machines, comprising: a first portion, a second portion which is articulated to the first portion, a third portion which is articulated to the second portion; the joint comprises: first stable inclination element for the stable inclination of the second portion with respect to the first portion, second stable inclination element for the stable inclination of the third portion with respect to the second portion, the first stable inclination element and the second stable inclination element being connected to a single lever and being operable by the single lever.

The present invention relates to a modular cleaner which has each constituent component modularized to have the connecting order changed in accordance with a usage condition or be used by selecting and coupling only the necessary constituents, the modular cleaner comprising: a body unit having a motor and an impeller therein to generate a suction force, and having a dust collecting part for storing impurities; a battery unit provided on the body unit and for applying a power source to the motor and impeller; a handle unit which can be detached from the body unit and has a grip part which can be held by a user; and a cleaning unit applying physical force to an object to be cleaned by coming into contact with the object to be cleaned, wherein coupling parts for coupling with the handle unit or cleaning unit are provided on both end parts of the body unit.

The invention relates to a floor cleaning device comprising a floor unit which is assigned a direction of advance parallel to a floor surface to be cleaned; a tool which, in an operating state, contacts the floor surface, the tool being movable relative to the floor surface by means of a drive; a guide member for guiding the floor cleaning device; and a joint assembly connecting the floor unit and the guide member in an articulate manner. When in a maneuvering operating state, the guide member can pivot about a first pivot axis and can be fixed or temporarily supported in the first pivot axis plane. As a result of the pivoting movement of the guide member about the first pivot axis, an advance effect brings about a moment of rotation of the floor unit on the floor surface that benefits the maneuvering of the floor cleaning device.

Disclosed is a bidirectional-spin cleaning structure which relates to cleaning equipment, including an inner-race cleaning disc and an outer-race cleaning disc, the inner-race cleaning disc is surrounded by the outer-race cleaning disc, an inner shaft is vertically fixed on the inner-race cleaning disc, an inner-race gear is mounted on the inner shaft, an outer shaft configured like a circular tube and rotatable about a center line of the inner shaft is sleeved outside the inner shaft, the outer shaft is securely attached to the outer-race cleaning disc, and an outer-race gear rotatable together with the outer shaft is mounted on the outer shaft; an autorotation-only transmission gear is engaged on the outer-race gear, a autorotation-only-only idle gear is engaged between the transmission gear and the inner-race gear; the bidirectional-spin cleaning structure further comprises a power mechanism configured to drive the transmission gear to rotate.

The present invention relates to a robot cleaner that cleans a surface to be cleaned using one or more mops while autonomously driving, and includes a body and a display unit provided on the body and to display information on the robot cleaner to be provided to a user, the display unit including a display means coupled to an upper surface of the body and to display a status of the robot cleaner on a screen, and a voice transmitting means coupled to the body and to output a sound from the robot cleaner, the display unit controlled based on a control signal transmitted from the user through an external control device.

The present invention provides a scrubbing robot, including a window scrubbing device, including a suction assembly configured to be sucked to a window body, a first travelling assembly configured to move on the window body, and a window body cleaning system; and a floor scrubbing device, including a second travelling assembly configured to move on a floor and a floor cleaning system, where the body of the floor scrubbing device has a mounting recess, and the window scrubbing device is configured to be capable of being embedded into and removed from the mounting recess. The scrubbing robot is an integrally functional cleaning robot integrating multiple functions of floor sweeping, floor scrubbing, and window scrubbing.

A robot cleaner includes a water tank forming a space to store water, a body forming an exterior and having a housing which forms a space in which the water tank is mounted, a pair of spin mops rotatably mounted at a lower side of the body, a first nozzle provided at the housing, a second nozzle provided at the tank and configured to couple to the first nozzle, and a fixing part generating a magnetic force when the tank is mounted in the housing to fix an arrangement of the tank mounted in the housing. The fixing part includes a fixing device (e.g., a magnet or metal) provided around a circumference of the second nozzle and a response fixing device (e.g., a magnet or metal) provided around a circumference of the first nozzle and having a shape corresponding to the fixing device. The first nozzle and the second nozzle are attached to each other by the fixing device and the response fixing device.

A nozzle for a cleaner has a nozzle housing, and first and second rotation cleaning units arranged on a lower side of the nozzle housing and spaced apart from each other. Each of the first and second rotation cleaning units includes a rotation plate coupled to a mop. The nozzle includes a first driving device having a first driving motor to drive the first rotation cleaning unit and a second driving device having a second driving motor to drive the second rotation cleaning unit. Further, the nozzle has a water tank mounted on the nozzle housing to store water. The nozzle housing includes driving unit covers arranged to surround each of the driving devices. At least one of the driving unit covers includes a first protruding surface, and a second protruding surface positioned higher than the first protruding surface.
