A method, applicable in a self-propelled surface-traveling robot system, for returning to a primary charging station, where the robot system comprises a surface-traveling robot and at least two charging stations for charging the robot, comprising the following steps: S: the robot establishes a map of an area; S: one of the charging stations is set as the primary charging station and the position of the primary charging station is recorded in the map of the area; and S: when finishing working, the self-propelled surface-traveling robot returns to the primary charging station according to the position of the primary charging station in the map of the area. In the method, applicable in a self-propelled surface-traveling robot system, for returning to a primary charging station of the present invention, the robot returns to the position of the set primary charging station after it finishes working so that the robot may be found by a user as accustomed at the position of the primary charging station when the robot is not working; and the starting point of the robot for each time working may also be determined, by setting the charging station at an important position where the robot is firstly needed to work as the primary charging station, facilitating arrangement of position for priority work.

A method for multipoint purification by a robotic air purifier, comprising the following steps: S: establishing a coordinate map of an area to be purified; S: the robotic air purifier moves within the area to be purified according to a preconfigured movement model, measuring air quality, remembering as level-1 pollution sources those points where a pollution value exceeds a preset threshold, and marking the coordinates of said points on the coordinate map; S: when having completed its movement over the area to be purified, the robotic air purifier moves to each level-1 pollution source point and performs an initial purification process, while at the same time measuring air quality, continuing in this way until the air quality at all said level-1 pollution sources complies with requirements.
