1. An electric vacuum cleaner comprising:
- an autonomous robotic vacuum cleaning unit autonomously moving on a surface to be cleaned and collecting dust on the surface; and
a station including a charging electrode to charge the autonomous robotic vacuum cleaning unit, whereinthe autonomous robotic vacuum cleaning unit includes;
a body case; and
a primary dust container including a container body provided in the body case and accumulating the dust collected by the autonomous robotic vacuum cleaning unit, a disposal port through which the dust in the container body is discharged, and a disposal lid for opening and closing the disposal port; and
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 autonomous robotic vacuum cleaning unit returns to the station, and opening the disposal lid so as to fluidically connecting the disposal port and the dust transfer pipe to each other; and
a secondary dust container accumulating the dust discharged from the primary dust container through the dust transfer pipe,wherein the disposal lid and the lever swing around a rotation center line crossing a direction toward a home position of the autonomous robotic vacuum cleaning unit.

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.
