Abstract (en)

[origin: EP3679847A1] An autonomous vacuum cleaner is provided which can clean efficiently around a vacuum cleaner body. An autonomous vacuum cleaner (1) includes a vacuum cleaner body (2) having a wheel (121) for travelling autonomously, a surroundings sensor (32) for detecting an obstacle around the vacuum cleaner body (2), a pivoting cleaner (3) that can clean around the vacuum cleaner body (2), and a controller (5) that controls the surroundings sensor (32) and the pivoting cleaner (3). The pivoting cleaner (3) includes 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 acting on the arm (21) from the outside. The motor (22) is controlled and driven on the basis of the presence or absence of an obstacle detected by the surroundings sensor (32), and travel of the vacuum cleaner body (2) is controlled on the basis of a load detected by the load sensor (23).
