SELF-PROPELLED VACUUM CLEANER

WIPO Patent Application WO/2019/043937

A1

[Problem] To provide a self-propelled vacuum cleaner that makes it possible to clean the surroundings of a vacuum cleaner body in an efficient manner. [Solution] A self-propelled vacuum cleaner (1) comprises a vacuum cleaner body (2) having wheels (121) for self-propulsion, a surroundings sensor (32) for sensing obstacles in the surroundings of the vacuum cleaner body (2), a rotary cleaning part (3) capable of cleaning the surroundings of the vacuum cleaner body (2), and a control unit (5) that controls the surroundings sensor (32) and the rotary cleaning part (3). The rotary cleaning part (3) has an arm (21) that protrudes outward from the vacuum cleaner body (2), a motor (22) that drives the arm (21), and a load sensor (23) that detects a load applied to the arm (21) from the outside. The motor (22) is drive-controlled on the basis of whether an obstacle detected by the surroundings sensor (32) is present, and traveling of the vacuum cleaner body (2) is controlled on the basis of the load detected by the load sensor (23).
