A turntable structure, a mopping device, and a robot are disclosed. The turntable structure comprises: a cleaning turntable, an adjusting component, and a pressure unit; one side of the cleaning turntable is connected to a cleaning piece; the adjusting component is slidably connected to the cleaning turntable along a target direction, and is located on the side of the cleaning turntable opposite to the cleaning piece, and the side of the adjusting component away from the cleaning piece is connected to a driving mechanism of the robot; the pressure unit is provided between the cleaning turntable and the adjusting component.

A floor maintenance machine has an adjustable deck assembly. The floor maintenance machine includes a deck supporting a floor cleaning implement. A lifting arm extends away from a frame of the floor maintenance machine and is rotatably coupled to the deck. The lifting arm is rotatably actuatable to adjust a position of the deck relative to the frame. A support member is rotatably coupled to the frame and movably coupled to the deck. A stop member is supported by the deck and extends toward the lifting arm for selective engagement therewith. When the lifting arm is rotated relative to the frame to lift the deck, the stop member is driven into the lifting arm to limit relative rotation between the lifting arm and the deck beyond a set angle.

A robot cleaner includes a first cleaning module including left and right spin mops configured to rotate clockwise or counterclockwise when viewed from above while being in contact with a floor, and a second cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while being in contact with a floor, the rolling member being spaced apart from the left and right spin mops in an anteroposterior direction. A controller controls rotational motion of the left and right spin mops and rotational motion of the rolling member.

A robot cleaner includes a rolling cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while in contact with a floor, a sensor unit, and a controller configured to detect a change in position of the robot cleaner and a change in load current of a motor connected to the rolling member based on data detected by the sensor unit. When there is a change in position and a change in load current, a specific area of a floor is determined to be a contaminated area.

An autonomously traveling floor washer autonomously performs an appropriate cleaning operation so that a washing liquid does not remain on a floor surface. In accordance with a cleaning schedule, the autonomously traveling floor washer autonomously travels and performs cleaning of the floor surface using a squeegee and the washing liquid. If a washing liquid discharge position at a taught data obtaining time is not included in a squeegee movement track calculated based on a position and a width of the squeegee at the taught data obtaining time, the cleaning schedule is modified so that the washing liquid discharge position is included in the squeegee movement track.
