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 mobile robot includes a body and a rotating plate rotatably installed on the body. A mop portion is attached to a lower surface of the rotating plate. And, a rotating ball that is vertically aligned with a rotating shaft of the rotating plate is rotatably installed on the rotating plate.

A nozzle for a cleaner includes a nozzle main body, a rotation cleaning unit rotatably connected to the nozzle main body, the rotation cleaning unit including a rotation plate provided with a mop, and a water supply flow path configured to supply water from a water tank to the rotation cleaning unit, the water supply flow path having an outlet. The rotation plates includes a central shaft, at least one water passage hole spaced apart from the central shaft in a radial direction to receive water directly from the outlet of the water supply flow path, and a water blocking rib located outside of the water passage hole in the radial direction.

A nozzle for a cleaner has a nozzle main body including an intake channel to suction air. The nozzle includes first and second rotary cleaning units spaced apart from each other in a lateral direction under the nozzle main body. Each of the first and second rotary cleaning units includes a rotary plate coupled to a dust cloth. The nozzle further includes a first driving device to drive the first rotary cleaning unit and a second driving device to drive the second rotary cleaning unit. The nozzle includes a water tank to store water. Further, the nozzle has a water supply channel to supply water in the water tank to the rotary cleaning units. The nozzle has a water pump and a pump motor to drive the water pump to pump the water to the dust cloth.

The present disclosure relates to a robotic cleaner. The robotic cleaner may be configured such that an imaginary plane passing mop contact portions having a small area passes through the center of gravity of the robotic cleaner, thereby travelling while the mops effectively scrub a floor surface.

A long rod cleaning machine can prevent swinging due to partial contact and also perform local cleaning. A scrubber includes an electric motor, a tip tool including a cleaning portion, a head to which the tip tool is attachable, a rod, and a rotator between the head and the rod. The tip tool is attached in a manner movable with a driving force from the electric motor. The head includes a peripheral portion surrounding the cleaning portion and including a surface-cleaning lateral portion to be in contact with a cleaning target surface together with the cleaning portion. The rotator includes a rotation restrictor connecting the head to the rod in a manner rotatable relative to the rod about at least two axes. The rotation restrictor partially or fully restricts rotation of the head.

A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

A nozzle for a cleaner includes a nozzle housing including a suction flow path through which air including dust flows and at least a portion of which extends in a front and rear direction. First and second rotation cleaning units are arranged on the lower side of the nozzle housing to be spaced apart from each other in a lateral direction. Each of the first and second rotation cleaning units includes a rotation plate adapted for attachment of a mop. A first driving device including a first driving motor drives the first rotation cleaning unit and a second driving device including a second driving motor drives the second rotation cleaning unit. A water tank mounted on the nozzle stores water to be supplied to the mop.
