Abstract
A vacuum cleaner includes a driving wheel, a cleaning part, a dust-collecting unit, a dust collection amount detection part, and a travel control part. The dust collection amount detection part detects the amount of the dust and dirt accumulated in the dust-collecting unit. The travel control part controls the driving of the driving wheel to make the vacuum cleaner travel autonomously. The travel control part makes the vacuum cleaner travel to a dust station in the case the amount of the dust and dirt detected by the dust collection amount detection part is equal to or more than a specified amount while the cleaning part performs cleaning. The travel control part further makes the vacuum cleaner undock from the dust station to restart the cleaning after the dust and dirt accumulated in the dust-collecting unit is transferred to a dust-collecting container at the dust station. The vacuum cleaning apparatus can adopt a downsized vacuum cleaner while ensuring convenience.
