ELECTRIC VACUUM CLEANER

Proposed is an electric vacuum cleaner in which a dust container inside an autonomous robotic vacuum cleaning unit can be fluidically connected to a station using the propulsive force of the cleaning unit moving to a dust discharge position. The cleaning unit (2) includes a body case (11), and a primary dust container (12) having: a container body (38) provided to the body case (11), the container body (38) accumulating a dust collected by the cleaning unit (2); a disposal port (41) discharging dust from inside the container body (38); and a disposal lid (42) opening and closing the disposal port (41). The station (5) includes a dust transfer pipe (25) connected to the disposal port (41) of the primary dust container (12); a lever (26) that is hooked by the disposal lid (42) while the cleaning unit (2) is homing, opening the disposal lid (42) and connecting the disposal port (41) and the dust transfer pipe (25); and a secondary dust container (68) in which dust discharged from the primary dust container (12) through the dust transfer pipe (25) is accumulated.
