Abstract: A robot vacuum comprises a main body including a suction part for suctioning dust, and a dust canister, attachable to and detachable from the main body, and which separates dust from the air suctioned through the suction part and stores same. The dust canister includes: a first chamber which separates dust from the air flowing in from the suction part and storing same, and which includes an inclined surface so that the lower area thereof becomes narrower than the upper area thereof; and a second chamber which includes a cyclone unit and which separates dust from the air flowing in from the first chamber and stores same, and the first chamber can further include ribs formed along the inclined surface to facilitate discharge of dust so as to prevent the dust stored in the first chamber from becoming stuck, due to bottlenecking, in the lower area of the first chamber.
