A vacuum cleaner includes a main casing, a driving wheel, a camera, a distance calculation part, a self-position estimation part, a mapping part, and a controller. The driving wheel enables the main casing to travel. The camera is disposed on the main casing to capture an image in traveling direction side of the main casing. The distance calculation part calculates a distance to an object positioned in the traveling direction side based on the captured image. The self-position estimation part calculates a position of the main casing based on the captured image. The mapping part generates a map of a traveling place by using three-dimensional data based on calculation results by the distance calculation part and the self-position estimation part. The controller controls an operation of the driving wheel based on the three-dimensional data of the map generated by the mapping part, to make the main casing travel autonomously.
