The self-propelled vacuum cleaner further includes a lifter that lifts the main body from a floor surface, and a controller that controls a drive unit and the lifter based on a detection result of the obstacle detector.

In contrast, when the depth is equal to or more than the predetermined value, the drive unit is controlled to cause the main body to run on the obstacle while being lifted by the lifter. This increases certainty of cleaning for the obstacle.
