Self-propelled vacuum cleaner

Abstract

Provided is a self-propelled vacuum cleaner including a main body, drive unit that moves and turns the main body, and an obstacle detector (an obstacle sensor, a ranging sensor, a camera) that detects an obstacle around the main body. 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. The controller controls the drive unit to cause the main body to avoid the obstacle while releasing lifting using the lifter when the obstacle has a depth in a traveling direction of the main body, the depth being smaller than a predetermined value. 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.
