The present disclosure discloses a multifunctional cleaning machine. The multifunctional cleaning machine includes a housing, a pipe, a nozzle, a plurality of wheel assemblies and a locking means. The pipe connected to the housing, the pipe including a water inlet and a water outlet, the water inlet being located on an upper side of the housing, the water outlet being located on a lower side of the housing, and the water inlet being configured for connecting to a high pressure water source. The nozzle connected to the water outlet. The wheel assemblies rotatably connected to the housing by the connecting assembly. The locking means connected to the housing and configured for locking the wheel assembly.

A center of gravity of a mobile cleaning robot may be positioned on an imaginary central longitudinal axis of the mobile robot. The center of gravity of the mobile robot may be positioned at a front side of an imaginary central horizontal line connecting spin rotation axes of left and right spin mops of the mobile robot. The center of gravity of the mobile robot may also be positioned at a front side of a center of gravity of a battery and a center of gravity of a water tank, and at a rear side of a center of gravity of a sweep module of the mobile robot.

The present disclosure relates to a robot cleaner including: a body including a lower body and an upper body for covering the lower body, the 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 a mop support portion 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 portion, thereby increasing a frictional force between the floor and the mops.

A cleaner according to the present disclosure includes: a mop module which includes a pair of spin mops that contacts a floor while rotating clockwise or counterclockwise when viewed from a top and is left-right symmetric with a virtual central vertical plane; a collection module which includes at least one collection unit that collects foreign substances from the floor at a position spaced apart from the mop module in a forward and backward direction, forms a collection space which stores the collected foreign substances, and is left-right symmetric with respect to the central vertical plane; and a body that connects the mop module and the collection module.

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 robot cleaner is provided, including a main body forming a robot cleaner exterior, a driver coupled to the main body to move the main body, a cleaning module coupled to the main body to suck dust from a traveling surface, a dust collector removing dust from air suctioned through the cleaning module, and a wet-mop module coupled to the main body to mop the traveling surface, wherein the wet-mop module includes a wet-mop module housing surrounding at least a portion of the main body and accommodating water in an internal space, a wet-mop module wheel disposed in the wet-mop module housing, a mop disposed between the wet-mop module housing and the traveling surface, and a wet-mop pump connected to the wet-mop module wheel to supply water to the mop in response to rotation of the wet-mop module wheel. Mopping may be performed without applying physical force of a person.

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.
