Disclosed is a method for controlling a mopping robot including a mopping member for mopping and cleaning a floor. The method includes: if the mopping robot has mopped a first area in a first state with the mopping member at a target degree of cleanliness, performing a mopping member cleaning operation; if the mopping robot has mopped a second area in a second state with the mopping member at the target degree of cleanliness, and if the mopping member satisfies the cleaning condition, performing the mopping member cleaning operation. An apparatus for controlling a mopping robot and a non-transitory computer-readable storage medium are also provided.

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. The nozzle also includes 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.

A cleaning assembly including a floor scrubber and a self-cleaning device matched with the floor scrubber is provided. The floor scrubber includes a housing connected to a handle. A motor is arranged in the housing. A scrubbing disc is arranged below the housing and is driven by the motor to rotate. The self-cleaning device includes a barrel connected to a support member used for supporting the floor scrubber. A wiper member is arranged in the barrel. When the floor scrubber is placed in the barrel to be dried, the support member supports the floor scrubber, and the wiper member abuts against the scrubbing disc; and when the scrubbing disc rotates or the wiper member moves, water and/or dirt on the scrubbing disc are/is wiped off by the wiper member.

A robot cleaner of the present disclosure includes: a robot cleaner including: a main body forming an outer shape; a water tank configured to contain water; a pair of rotary mops configured to rotate in contact with a floor to move the main body; a drive motor configured to rotate the pair of rotary mops; a pump connected to the water tank for injecting the water to the rotary mop; and a controller configured to determine whether the water in the water tank is insufficient based on an output current of the drive motor indicating a water content of the rotary mops. Accordingly, the robot cleaner may be effective in terms of cost and space utilization because it does not have a separate water quantity sensor and can measure the water quantity of the rotary mop of the robot cleaner.

The present disclosure relates to a docking apparatus for a mobile robot including a sterilization unit, which emits germicidal light to a floor cloth to sterilize the floor cloth, and which includes: a germicidal lamp which vertically overlaps with the floor cloth of the mobile robot, and emits the germicidal light to a front end thereof; a diffusing part for diffusing the germicidal light to a rear end of the germicidal lamp; and a converging part for converging the germicidal light to a rear end of the diffusing part.

A system for enabling spot cleaning includes a mobile computing device and a mobile cleaning robot. The mobile computing device includes at least one camera configured to capture images of an environment, and at least one data processor configured to (a) establish, based at least in part on first information provided by the at least one image sensor, a coordinate system in the environment, (b) determine, based at least in part on second information provided by the at least one camera, a first set of coordinates of a region at a first location, (c) determine, based at least in part on third information provided by the at least one camera, a second set of coordinates of a mobile cleaning robot at a second location, (d) send the first set of coordinates and second set of coordinates, or coordinates of the first location relative to the second location, to the mobile cleaning robot, and (e) send an instruction to the mobile cleaning robot to request the mobile cleaning robot to travel to the first location.

A cleaning robot including a main body; a motion driver configured to move the main body; a pad motor configured to rotate a pad below a bottom surface of the main body; a light source configured to irradiate light to the pad; and at least one processor configured to, based on an amount of reflection of the light from the pad, control rotation speed of the pad motor and/or control the motion driver to return the cleaning robot to a docking station.

A power scrubber including a telescopic shaft, a power receptacle, a handle, a power head, a pivot coupling, a first scrubber head, a second scrubber head, and a drive. The power receptacle and the handle are each positioned adjacent the first end. The pivot coupling couples the power head to the second end and is operable to adjust an angle of the power head relative to the shaft axis. The drive is coupled to and driven by the power head and extends along a longitudinal axis. The drive includes a first connector selectively engaging the first scrubber head with a center of the first scrubber head aligned with the longitudinal axis and a second connector selectively engaging the second scrubber head with a center of the second scrubber head aligned with the longitudinal axis. The first connector is connected to the first scrubber by a bayonet coupling.

The present disclosure relates to a robot cleaner including a body having a space for accommodating a battery, a water container, and a motor therein, a first rotary plate having a lower portion to which a first mop is coupled, and a second rotary plate having a lower portion to which a second mop is coupled, in which the body includes a bottom surface disposed to be directed toward a floor, and mop support portions disposed on the bottom surface, protruding downward, and configured to be in contact with the first mop and the second mop, and the mops are bent by being brought into contact with the mop support portions, thereby increasing a frictional force between the floor and the mops.
