A multi-robot system includes a first a mobile cleaning robot that has a local storage device to store a persistent map of an environment, at least one sensor to sense the environment, and a control module. The control module is configured to: control the mobile cleaning robot to navigate in the environment using the persistent map and sensing data provided by the at least one sensor, share the persistent map with a second mobile cleaning robot, and coordinate with the second mobile cleaning robot to perform cleaning tasks.

A docking station for a mobile cleaning robot can include a base and a canister. The base can be configured to receive at least a portion of the mobile cleaning robot thereon. The base can include an electrical power interface configured to provide electrical power to the mobile cleaning robot. The canister can be connected to the base and can be located at least partially above the base. The canister can include a debris bin to receive debris from the mobile cleaning robot.

A trolley and method for loading and unloading cleaning robots into a trolley, including for storing, emptying and supplying energy to cleaning robots. The trolley includes an energy supply unit, storage compartments, each storage compartment having a charging contact which is designed to be contacted with a cleaning robot arranged in the corresponding storage compartment to supply the cleaning robot with energy, transport wheels configured to move the trolley over a substrate, a suction system having a foldable suction platform configured to empty one of the cleaning robots arranged on the suction platform, a lift system with a foldable receiving element configured to transport the cleaning robots individually by way of the receiving element in its unfolded state to the storage compartments and away from the storage compartments, and at least one door element configured to close or expose the foldable receiving element and the foldable suction platform.

A method for emptying cleaning robots and cleaning system, having a dirt collection unit and a suction interface using a trolley, configured to store the plurality of cleaning robots outside their cleaning phase in which they carry out cleaning tasks, and which has a suction system with a foldable suction platform, a suction opening, a dirt container, and a blower. The method includes the steps of unfolding the suction platform of the trolley, if it is folded, so that it is arranged on a substrate on which the trolley stands in an operational set-up position, arranging one of the cleaning robots on the unfolded suction platform, aligning the suction interface to the suction opening, and activating the blower in order to empty the cleaning robot arranged and aligned on the suction platform so that dirt is transported from the dirt collection unit into the dirt container.

A cleaning base station including a cleaning body, a sewage collecting body, and a draining structure is provided. The cleaning body is defined with a filtering hole, and the sewage collecting body is connected with the cleaning body to collect sewage flowing out from the filtering hole. The draining structure is detachably connected with the sewage collecting body. The sewage collecting body can be disassembled from the draining structure to be cleaned since the draining structure and the sewage collecting body are detachably connected, which is very convenient.

A water tank assembly including a tank body and a one-way valve is provided. The tank body is defined with a clean water cavity communicated with an external pipeline through a water inlet channel, the external pipeline is capable of transporting water to the clean water cavity. The one-way valve is arranged in the water inlet channel and has a first and a second state. During delivering clean water to the clean water cavity, the one-way valve is in the first state to allow water in the external pipeline to be delivered to the clean water cavity, and when clean water is stopped to supply to the clean water cavity, the one-way valve is changed to the second state to restrict the water in the water inlet channel flowing out, such that outflow of the clean water from the water inlet channel is blocked when the external pipeline is removed.

A robot maintenance station and a robot cleaning system. The robot maintenance station includes a dock base and a maintenance station body, the maintenance station body is configured on the dock base and provided with a suction unit, the suction unit is configured to provide suction power for sucking garbage. The maintenance station body is provided with a garbage receptacle and a suction tube, the suction tube is in flow communication with the suction unit and is configured to guide the garbage into the garbage receptacle, and the garbage receptacle is detachably mounted at a side wall of the maintenance station body. The embodiments realize automatic emptying of the dust box of the cleaning robot, thereby reducing user burden and improving user experience.

A docking station for a robotic vacuum cleaner has a pneumatic transfer mechanism that is used to direct air to the robotic vacuum cleaner to thereby transfer dirt from the robotic vacuum cleaner to a docking station.

A cleaning system includes a cleaning vehicle that cleans a predetermined travel route, a maintenance facility provided at a specified position on the travel route and performs maintenance on the cleaning vehicle, and a control device that controls them. The control device executes interruption and maintenance control in response to a state of the cleaning vehicle satisfying a predetermined maintenance condition during execution of the cleaning by the cleaning vehicle. The interruption and maintenance control includes first control for interrupting the cleaning performed by the cleaning vehicle, causing the cleaning vehicle to move to the specified position, and causing the maintenance facility to perform the maintenance on the cleaning vehicle, and second control for causing, after the first control, the cleaning vehicle to move to an interruption position at which the cleaning was interrupted, and causing the cleaning vehicle to resume the cleaning from the interruption position.

A system for refilling, emptying and/or recharging of an autonomous floor cleaner includes a docking station adapted to be coupled with a household plumbing infrastructure. The docking station can be provided on a household appliance, which may be a toilet, a dishwasher, or another appliance coupled with the plumbing infrastructure.
