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.

Abstract: In a vacuum cleaner electric blower is driven by power supplied by a secondary battery. A dust-collector is configured to catch and collect dust and dirt sucked by driving the electric blower. A detector is configured to detect a remaining amount of the secondary battery. A controller is configured to control suction force of the electric blower. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is equal to or less than a predetermined value, the controller sets the parameter to reduce the suction force of the electric blower for the next cleaning. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is not equal to or less than the predetermined value, the controller sets the parameter to increase the suction force of the electric blower for the next cleaning.
