A robot cleaner includes a main body which forms an external shape; two or more spin mops which rotate in a clockwise or counterclockwise direction when viewed from above and mop a floor with a damp cloth, and move the main body; and a cleaning module which is positioned in front of the spin mops and collects foreign substance existing on a cleaning target surface, wherein the cleaning module includes: a housing which is coupled to the main body and opened at a lower side; a dust container which forms a space for accommodating foreign substance and is positioned to be detachable in a lower side direction of the housing; and an agitator which is positioned inside the housing, and sends foreign substance existing on the cleaning target surface to the dust container by a rotation operation.

A mobile robot is configured to move a main body and rotate a cleaning cloth by means of a motor to clean a surface. A location change of the main body is analyzed to determine a traveling state of the robot. The absence of the cleaning cloth is detected and the operation of the robot is controlled based on the detected travelling state. A user is notified about the absence of the cleaning cloth.

A cleaning robot includes a main body, a drive assembly and a cleaning assembly. The main body includes a bottom part. The cleaning assembly includes a mounting part, a wiping part and a release part. The mounting part is positioned on the bottom part. The mounting part includes a first rail, a second rail, and a first positioning part. The wiping part is positioned on the mounting part and includes a second positioning part, the wiping part is movable from first ends of the first rail and the second rail to second ends thereof until the second positioning part abuts against the first positioning part whereby the wiping part is fixed on the mounting part. The release part is positioned on the mounting part and configured to separate the second positioning part from the first positioning part whereby the wiping part is detached from the mounting part.

A cleaning machine may include: a first brush including a first brush shaft and a first brush body held by the first brush shaft; a second brush including a second brush shaft and a second brush body held on the second brush shaft; a first brush attaching member having a first shape, wherein one end of the first brush shaft is detachably attached to the first brush attaching member; and a second brush attaching member having a second shape, wherein one end of the second brush shaft is detachably attached to the second brush attaching member. The one end of the first brush shaft may have a first corresponding shape that corresponds to the first shape. The one end of the second brush shaft may have a second corresponding shape that corresponds to the second shape. Other end of the first brush shaft may have the second corresponding shape.

The present disclosure provides a cleaning robot, a cleaning module, a cleaning assembly, a base and a cleaning system, wherein the cleaning robot includes: a robot apparatus, configured to carry the cleaning module; and a first replacement mechanism, configured to enable the robot apparatus to be loaded with the cleaning module, and replace a cleaning module carried on the robot apparatus with the loaded cleaning module. When the cleaning robot is loaded with a new cleaning module, the loaded new cleaning module replaces the old cleaning module originally carried on the cleaning robot, in this way, the assembling and disassembling of the cleaning modules on the cleaning robot can be performed synchronously.

A liftable and rotatable mop structure and a cleaning machine are provided. The liftable and rotatable mop structure includes a mop unit which includes a mop, a turntable and a rotatable shaft, wherein the mop is connected with the turntable, and the rotatable shaft is connected with the turntable; the rotatable shaft functions to lift the turntable and drive the turntable to rotate, and includes an inner shaft and an outer shaft surrounding the inner shaft; a limiting structure is arranged between the inner shaft and the outer shaft so that the inner shaft and the outer shaft are movable relative to each other in an axial direction but are limited in a circumferential direction.

A mobile cleaner includes a dust housing, an agitator, and a dustpan. The dust housing has a collection opening facing a surface. The agitator is rotatably disposed within the dust housing and is exposed to the surface through the collection opening. The agitator is configured to move foreign material from the floor into the dust housing. The dustpan directs the foreign material moved by the agitator into the dust housing. The dustpan extends around a portion of an outer circumferential surface of the agitator and is configured to rotate independent of the agitator.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, a controller for controlling the operation of the autonomous floor cleaner, and warning system for issuing a warning based on the detection of moisture inside the robot. Methods for issuing a warning are disclosed.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

The invention relates to a floor cleaning system, comprising a user-guided floor cleaning machine for cleaning a floor surface, a sensor device, a control device, and an actuatable display device, wherein the floor cleaning machine comprises an operating device for a user, a chassis for moving the cleaning machine over the floor surface, and at least one cleaning device having a cleaning tool and preferably a drive device for the cleaning tool, wherein, during operation of the floor cleaning machine, a cleaning path along which, proceeding from a starting point, the cleaning machine travels over the floor surface can be determined by the control device on the basis of signals from the sensor device, and wherein the control device actuates the display device in order to display cleaning-related information, depending upon the cleaning path along which the cleaning machine is determined to have traveled.
