To reduce time to return a self-propelled vacuum cleaner having a rechargeable battery to a charging stand by quickly detecting a direction where the charging stand is present in a case such as where the self-propelled vacuum cleaner needs to be charged.
A self-propelled electronic device is configured to receive power supply from a charging stand placed at a predetermined position and to automatically travel to positions away from the charging stand. The self-propelled electronic device includes: a travel control part that controls the rotation of wheels and automatically moves the device; a rechargeable battery that supplies power, used for performing travel control, during the automatic travel; a charging stand searching part that searches the position of the charging stand; and a control part. When the control part determines that the electronic device needs to return to the charging stand, the control part executes return processing in which the electronic device is rotated in a static state after being put into the static state by the travel control part, and then, moved in a direction, where the charging stand is present, when the charging stand searching part searches the direction, where the charging stand is present, and detects the direction of the charging stand.
