• a suction part having a flow path through which air flows;
• a dust separating part configured to separate dust from air sucked through the suction part;
• and
• a suction motor configured to provide a flow force of air,
• wherein the dust separating part comprises:
• a first cyclone part configured to separate debris from air sucked into the suction part;
• and
• a second cyclone part configured to separate debris from air passing through the first cyclone part, and
• wherein the second cyclone part comprises:
• a first flow path through which air flows toward the suction motor;
• a second flow path through which air having passed through the first flow path flows to a side opposite to the suction motor;
• and
• a third flow path through which air having passed through the second flow path toward the suction motor.
