    摘要： A vacuum cleaner for performing autonomous driving may include: a main body; a driving unit; a suctioning unit; a plurality of sensors for sensing obstacles present in each direction; and a control unit for controlling the driving unit to move the main body on the basis of a preset driving pattern. The control unit uses sensors provided at the front side of the main body and a first side of the both sides of the main body so as to detect whether entry into a corner area among cleaning areas is made while driving along the preset driving pattern, and controls the driving unit such that the first side of the main body comes into contact with a first wall forming the corner area at least one time when the main body enters the corner area.

    摘要： A tab cleaning apparatus is provided. The tab cleaning apparatus includes: cleaning assemblies, where the cleaning assembly is provided with an air channel inside, and the air channel is provided with an air inlet and an air outlet; and a suction assembly, where the suction assembly is connected to the cleaning assembly, the suction assembly is connected to the air outlet, the suction assembly operates to make air enter the cleaning assembly from the air inlet so as to form a negative pressure zone on the side of the air inlet, and a tab is placed in the negative pressure zone so as to clean the tab. The tab cleaning apparatus of this application can remove metal filings and other impurity particles at tabs, thereby improving the cleanliness of cells, reducing the self-discharge failure rate of cells, and improving the safety of cells.

    摘要： A modular vacuum system includes a plurality of power heads configured to be removably coupled to a plurality of canisters, each canister having a debris collection chamber of a different capacity, a first power source configured to output a first voltage, and a second power source configured to output the first voltage. A first power head of the plurality of power heads is configured to receive the first power source, and includes a first suction motor rated to operate at a first performance level defined by the first voltage. A second power head of the plurality of power heads is configured to receive the first power source with the second power source, and includes a second suction motor rated to operate at a second performance level greater than the first performance level.

    摘要： A method for operating a robotic device. Usage data and a first location of the robotic device are determined. A first sensor of the robotic device captures first data indicative of an environmental characteristic of the first location. A first operational parameter of a first actuator is adjusted based on the first data while the robotic device is at the first location. A debris map of the environment is formed based on debris data output by a second sensor configured to sense debris on a floor. A request for cleaning service at a location is received, wherein the robotic device is one of a plurality of robotic devices that provides surface cleaning services to a plurality of users. The robotic device to respond to the request is determined based on location, fill volume of a debris container, battery charge, and availability of each of the plurality of robotic devices.
