Abstract: The present invention provides a dust suction and charging device for a floor sweeping robot and a dust suction and charging method thereof. The floor sweeping robot has a floor sweeping robot body with a dust box arranged on one side of the body. A dust-box discharge port is formed on the dust box and corresponds to a maintenance-station dust suction port. The maintenance-station dust suction port can be communicated with the dust-box discharge port by pressing an outer surface of the maintenance-station dust suction port. Advantages: (1) the charging, dust removal and maintenance operations on the floor sweeping robot are realized simultaneously; and, (2) dust in the dust box of the floor sweeping robot is sucked into a dust bag of the maintenance station by vacuum, so it is unnecessary to take out the dust box. Therefore, it is convenient to clean and will not pollute the external environment.

Abstract: In general, the present disclosure is directed to a hand-held surface cleaning device that includes a relatively compact form-factor to allow users to store the same in a nearby location (e.g., in a drawer, in an associated charging dock, on a table top) for easy access to perform relatively small cleaning tasks that would otherwise require retrieving a full-size vacuum from storage. A hand-held surface cleaning device consistent with aspects of the present disclosure includes a body (or body portion) with a motor, power source and dust cup disposed therein. The body portion also functions as a handgrip to allow the hand-held surface cleaning device to be operated by one hand, for example.

Abstract: A cleaner head for a cleaning appliance, the cleaner head comprising: a housing defining a suction chamber; and a sole plate defining a downwardly-directed opening through which dirt can enter the suction chamber. The cleaner head further comprises a hollow deformable seal extending from a rear portion of the housing, the hollow deformable seal having a width at least equal to a width of the opening in the sole plate, and having a lower sealing surface that extends in a downward and rearward direction from a rear edge of the housing such that, in use, the hollow deformable seal is biased against and conforms to a surface being cleaned in order to maintain a seal between the cleaner head and the surface being cleaned.

Abstract: A power-saving robot system includes at least one peripheral device and a mobile robot. The peripheral device includes a controller having an active mode and a hibernation mode, and a wireless communication component capable of activation in the hibernation mode. A controller of the robot has an activating routine that communicates with and temporarily activates the peripheral device, via wireless communication, from the hibernation mode. In another aspect a robot system includes a network data bridge and a mobile robot. The network data bridge includes a broadband network interface, a wireless command interface, and a data bridge component. The data bridge component extracts serial commands received via the broadband network interface from an internet protocol, applies a command protocol thereto, and broadcasts the serial commands via the wireless interface. The mobile robot includes a wireless command communication component that receives the serial commands transmitted from the network data bridge.

Abstract: A vacuum cleaner nozzle having a rotatable member for picking up particles from a surface to be cleaned, and an external cleaning apparatus for removing articles entangled to the rotatable member. The nozzle includes a support surface provided on a radially projecting member of the rotatable member, and a cleaning member provided on the external cleaning apparatus. During rotation of the rotatable member, the cleaning member co-operates with the support surface to remove entangled articles from the rotatable member.
