A robot cleaner includes a body to travel on a floor; an obstacle sensing unit to sense an obstacle approaching the body; an auxiliary cleaning unit pivotably mounted to a bottom of the body, to be extendable and retractable; and a control unit to control extension or retraction of the auxiliary cleaning unit based on a pivot angle formed by the auxiliary cleaning unit with respect to a travel direction of the body when the obstacle is sensed.

Disclosed herein are a cleaning robot and a method of controlling the same. The cleaning robot according to one embodiment includes a modular in which one or more modules configured to support different functions are integrated, and a controller configured to control the overall operation of the cleaning robot.

A base station performs a service treatment on a floor processing device, wherein the base station has a basic housing with an interface for docking the floor processing device. In order to support docking in a purely mechanical way, the base station has a guide extension arm allocated to the interface and facing away from the basic housing with a predominant longitudinal extension for exclusively mechanically guiding a docking movement of the floor processing device to the interface, wherein an outer contour of the guide extension arm as observed in a vertical top view tapers proceeding from the basic housing up to a free end area of the guide extension arm facing away from the basic housing.

A system of robotic cleaning devices and a method of a master robotic cleaning device of controlling at least one slave robotic cleaning device. The method performed by a master robotic cleaning device of controlling at least one slave robotic cleaning device includes detecting obstacles, deriving positional data from the detection of obstacles, positioning the master robotic cleaning device with respect to the detected obstacles from the derived positional data, controlling movement of the master robotic cleaning device based on the positional data, and submitting commands to the at least one slave robotic cleaning device to control a cleaning operation of said at least one slave robotic cleaning device, the commands being based on the derived positional data, wherein the cleaning operation of the slave robotic cleaning device is controlled as indicated by the submitted commands.

The invention relates to a floor cleaning system, having a mobile floor cleaning apparatus that comprises at least one cleaning unit for cleaning a floor surface, a reservoir for receiving a cleaning liquid, a dirt receiving device for taking up dirty liquid from the floor surface, and a dirty liquid container into which the dirty liquid is transferable; and further having a docking station for the floor cleaning apparatus, which is docked thereto in a docked position; wherein the docking station has at least one supply conduit with a connection element arranged thereon, the floor cleaning apparatus having at least one liquid conduit with a connection element arranged thereon; wherein the floor cleaning apparatus comprises a rinsing device on or in the dirty liquid container; and wherein, when the floor cleaning apparatus is in the docked position, the connection elements are coupled to one another such that the reservoir is fillable with the cleaning liquid via the at least one liquid conduit and a rinsing liquid for rinsing the dirty liquid container is applicable to the rinsing device via the at least one liquid conduit.

An autonomous moving device wireless charging system, including an autonomous moving device and a wireless charging station, the wireless charging station includes a wireless charging transmitting end; the autonomous moving device includes: a wireless charging receiving end, the wireless charging transmitting end wirelessly transmits a charging signal to the wireless charging receiving end to transmit electric energy; a charging battery, electrically connected to the wireless charging receiving end, to receive the electric energy transmitted from the wireless charging receiving end; a wireless charging locating module, the wireless charging locating module determines whether the autonomous moving device is at a charging location; a driving module; and a control module, connected to the wireless charging locating module and driving module, when the wireless charging locating module determines that the autonomous moving device is at the charging location, controlling the driving module, to make the autonomous moving device dock at the charging location.

An orientation system includes a base station comprising a light emitter that projects a pattern onto a projection surface of a space, an auxiliary station including an auxiliary emitter that projects an auxiliary pattern onto the projection surface, and a robot including a moveable base supporting an imaging device. The robot detects the pattern and the auxiliary pattern with the imaging device, and determines a location of the robot within the space based on the pattern.

A vacuum cleaning system including a robotic unit including a traction arrangement, and a docking interface for receiving a handheld vacuum cleaner, and a handheld vacuum cleaner configured to be docked with the docking interface. The handheld vacuum cleaner includes a vacuum motor for drawing air through a suction flow path defined by the robot unit when docked with the docking interface. The handheld vacuum cleaner includes a main body from which extends a battery pack. When the handheld vacuum cleaner is docked with the docking interface, it is configured such that the battery pack extends over the top of at least part of the robotic unit. Conveniently, the robotic unit and the handheld vacuum cleaner may share one or more common suction tools, which means that both machines can be optimised for the surfaces they are intended to clean.

The present disclosure relates to a cleaner station that includes a catching device and a receiving space capable of receiving various cleaning modules used in a cleaner. The cleaning station includes: a housing which includes an outer wall surface; a housing cover which is openably and closably coupled to the housing and forms an external appearance; a receiver that receives a cleaning module of the cleaner; and a catching device which is formed to allow an auxiliary suction port of the cleaner to be mounted thereon. The receiver can be separated from the outside by the housing cover, so that the cleaning module is mounted in a space that does not expose the cleaning module to the outside, and the aesthetic impression can be improved. The catching device allows the auxiliary suction port including a wet mop to be mounted on the outside of the cleaner station, so that problems caused by dripping water can be prevented.

A method of managing a plurality of washrooms in a facility for servicing by service personnel and, more particularly, for establishing servicing operations which provide for service of at least selected of the dispensers before their consumable product supply falls below a pre-selected refill value.
