1. An electronic device comprising:
a dust suction part;
a body part including a motor for generating suction force of the electronic device and a battery module operable by a power source of the motor; and
an extension pipe combined between the dust suction part and the body part and providing a passage for moving foreign substances absorbed through the dust suction part to the body part,
wherein the extension pipe includes
a pipe-type external case,
a supercapacitor module disposed in an inner space of the pipe-type external case and including a hollow space used as the passage, and
a first docking connector for transmitting electrical energy of the supercapacitor module to the motor when the body part is combined to the extension pipe, and
wherein the hollow space is formed to penetrate the supercapacitor module in a direction in which the absorbed foreign substances move.
