A cleaner includes a body, a left spin-mop module located on a left side of the body and a right spin-mop module located on a right side of the body, each of the left spin-mop module and the right spin-mop module being rotatable about a first rotational axis to perform mopping, a left spin-drive unit disposed on the left side of the body, the left spin-drive unit being configured to provide a force to rotate the left spin-mop module; and a right spin-drive unit disposed on the right side of the body, the right spin-drive unit being configured to provide a force to rotate the right spin-mop module. Each of the left spin-drive unit and the right spin-drive unit has a second rotational axis that extend in a direction different from the first rotational axis of the respective left spin-drive unit and the right spin-drive unit.

A cleaner includes a first cleaning module including a left spin mop and a right spin mop that come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module that comes into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module that supplies water to the first cleaning module. A water tank is disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.

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 method for operating a floor cleaning machine on a floor surface. The floor cleaning machine includes a cleaning-liquid container, a dirty-liquid container, a chassis for moving the floor cleaning machine over the floor surface, a cleaning means and a dirty-liquid take-up means. The method includes: sensing an amount of cleaning liquid supplied from the cleaning-liquid tank to the cleaning means within a first time interval while moving the floor cleaning machine; sensing an amount of dirty liquid being removed from the dirty-liquid take-up means to the dirty-liquid container within a second time interval while moving the floor cleaning machine; comparing the sensed amount of cleaning liquid against a first threshold value; comparing the sensed amount of dirty liquid against a second threshold value; outputting a first fault signal if the sensed amount of cleaning liquid is greater than the first threshold value and the sensed amount of dirty liquid is less than the second threshold value.

The present disclosure relates controlling a robot cleaner that moves based on a rotation of a spin mop. The controlling the robot cleaner includes determining a control command; operating the spin mop and performing a reference motion by the robot cleaner; detecting a movement of the robot cleaner which performs a reference motion by a motion detection sensor; and controlling travel of the robot cleaner to achieve the control command.

The present disclosure relates to the field of cleaning robot technology, and in particular to a base station, which is adapted for cooperating with a cleaning robot having a mop member that is configured to mop a floor, the base station includes a base station body and a mop member cleaning device arranged on the base station body, and the mop member cleaning device is configured to clean the mop member. The base station further includes a scraping and blocking member, the scraping and blocking member is configured to prevent cleaning fluid from splashing during a process of the mop member cleaning device cleaning the mop member.

A portable surface treatment tool is provided, which is configured for attachment to a suction controller. The portable surface treatment tool is configured for use with vertical, overhead, inclined and horizontal surfaces and includes a head and a handle coupled to the head. The head includes: a rotatable surface treatment unit configured to engage a surface to be treated; a motor configured to drive the rotatable surface treatment unit; and a shroud substantially encasing at least a portion of the rotatable surface treatment unit, the shroud defining a suction region proximal the rotatable surface treatment unit. The suction region is configured to suck fluid from a surface to be treated. The shroud defines a suction connection formation configured to be coupled to a source of suction supplied by a suction controller, the suction connection formation being in fluid communication with the suction region to remove fluid from a surface to be treated.
