Abstract
There is provided an electric vacuum cleaner capable of further cleaning up air discharged from a whirling chamber which swirls air to separate dust from the air by inertial force, as well as capable of downsizing the electric vacuum cleaner's body. To this end, the electric vacuum cleaner includes: a whirling chamber configured to swirl air containing dust around a central axis to separate dust from the air containing dust, the whirling chamber having a discharge port for discharging air in the whirling chamber; a discharge pipe provided in the whirling chamber along the central axis, the discharge pipe communicating with the discharge port; and a filter provided on a downstream side of the discharge port. The filter is positioned outside of the discharge pipe on a projection plane perpendicular to the central axis.
