A cleaner includes a body forming an external appearance, a rotating plate provided at a lower side of the body, a mop unit coupled to a lower side of the rotating plate so as to be in contact with a floor, a spin shaft connected to an upper side of the rotating plate so as to rotate the rotating plate, a water supply reservoir configured to surround a periphery of the spin shaft and spaced apart from the spin shaft so as to define a water supply space, and a water supply module configured to supply water to the water supply space. The rotating plate forms a water supply hole configured to interconnect the water supply space and the lower side of the rotating plate.

The present disclosure provides a surface cleaning apparatus that includes a housing including a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and apparatus is provided with a base adapted for movement across a surface to be cleaned, a brushroll removably mounted within the base, and a brushroll latch for securing the brushroll to the base. The brushroll latch can be captured by a portion of a nozzle assembly to prevent unintended release of the brushroll.

The present disclosure provides a surface cleaning apparatus that includes a housing including a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. Methods for self-cleaning a surface cleaning apparatus are also provided.

A floor maintenance machine includes a chassis, a floor-cleaning implement adapted for engagement with the floor, and a service cabinet. The floor-cleaning implement is supported by the chassis. The service cabinet is coupled to the chassis and defines a cavity. The cavity receives a plurality of fluid access points collectively therein.

A cleaning robot includes a cleaning device for cleaning and a driving device for travelling. The cleaning robot is provided with an operating mode and a self-cleaning mode. The self-cleaning method includes: controlling the cleaning robot to enter the self-cleaning mode; controlling the cleaning device to operate and the driving device to stop operating after entering the self-cleaning mode. In the embodiments of the present disclosure, efficient, integrated, and comprehensive cleaning tasks can be implemented by a cleaning robot by controlling the cleaning robot to enter a self-cleaning mode and complete a self-cleaning operation under a particular condition.

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. The controller is configured to determine 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, and determine that a specific area of the floor is a contaminated area when there is a change in the position and a change in the load current.

The present disclosure provides a surface cleaning apparatus that mechanically removes liquid and debris from a brushroll and stores the mechanically-removed liquid and debris onboard the apparatus in a first collection area. The surface cleaning apparatus also collects further liquid and debris from the brushroll by a source of suction including a vacuum motor or a pump and stores the collected liquid and debris onboard the apparatus in a second collection area.

A floor maintenance machine includes a chassis, a floor-cleaning implement adapted for engagement with the floor, and a service cabinet. The floor-cleaning implement is supported by the chassis. The service cabinet is coupled to the chassis and defines a cavity. The cavity receives a plurality of fluid access points collectively therein.

A wet-cleaning appliance, in particular a wet mop, has a cleaning roller, which can be rotated about a roller axis, and having a wetting device for applying a liquid to the cleaning roller. In order to provide for regeneration of the cleaning roller with the best possible result, it is proposed that the wet-cleaning appliance should have a wiper device, in particular a wiper lip, which can be displaced onto the cleaning roller and is intended for assisting in removing liquid and/or dirt from the cleaning roller and/or for assisting in applying liquid to the cleaning roller.
