  • Patent number: 11744428
    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.

  • Patent number: 11221629
    Abstract: A vacuum cleaner that can achieve efficient and accurate autonomous traveling. An obstacle detection part detects an object corresponding to an obstacle outside a main casing. A map generation part generates a map indicating information on an area having been traveled by the main casing, based on detection of the object by the obstacle detection part and a self-position estimated by a self-position estimation part during traveling of the main casing. A controller controls an operation of a driving wheel to make the main casing autonomously travel. The controller includes a traveling mode for controlling the operation of the driving wheel so as to make the main casing autonomously travel along a traveling route set based on the map. The controller determines whether or not to change the traveling route for next time based on the obstacle detected by the obstacle detection part during the traveling mode.
