Title:
SELF-PROPELLED VACUUM CLEANER
Document Type and Number:
WIPO Patent Application WO/2020/017235
Kind Code:
A1
Abstract:
A self-propelled vacuum cleaner (100) includes a body, a driving unit (130) that moves and turns the body, and an obstacle detecting unit (an obstacle sensor (173), a range sensor (174), and a camera (175)) for detecting an obstacle around the body. The self-propelled vacuum cleaner further includes a lifting unit (133) for lifting the body from a floor, and a control unit (150) for controlling the driving unit (130) and the lifting unit (133) on the basis of detection results obtained by the obstacle detecting unit. When the depth of an obstacle in the traveling direction of the body is smaller than a predetermined value, the control unit (150) controls the driving unit (130) such that the body avoids the obstacle in a state in which lifting by the lifting unit (133) is released. Meanwhile, when the depth is larger than or equal to the predetermined value, the control unit (150) controls the driving unit (130) such that the body runs on the obstacle in a state in which lifting by the lifting unit (133) is enabled. This configuration improves the reliability of obstacle cleaning.
