Abstract
An electric vacuum cleaner in which a dust container inside an autonomous robotic vacuum cleaning unit can be fluidically connected to a station using propulsive force of the cleaning unit moving to a dust discharge position. The cleaning unit includes a body case, and a primary dust container including: a container body accumulating dust collected by the cleaning unit; a disposal port discharging dust from inside the container body; and a disposal lid opening and closing the disposal port. The station includes a dust transfer pipe connected to the disposal port of the primary dust container; a lever hooked by the disposal lid while the cleaning unit is homing, opening the disposal lid and connecting the disposal port and the dust transfer pipe; and a secondary dust container in which dust discharged from the primary dust container through the dust transfer pipe is accumulated.
