Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. The collection chamber has an inlet opening through which debris-entrained air enters the collection chamber. When the vacuum cleaner is off, an internal valve prevents debris from leaving the collection chamber through the inlet opening. The internal valve is movable from a first sealed position, in which the internal valve covers the chamber inlet opening, to a second unsealed position in which the internal valve does not cover the chamber inlet opening.

A wearable vacuum cleaner includes a harness configured to support the wearable vacuum cleaner on a user's back, a housing connected to the harness, a suction motor assembly disposed within the housing and operable to create a working airflow, and a collection bin configured to receive debris separated from the working airflow. The collection bin includes an opening adjacent a bottom portion of the collection bin and a lid moveably coupled to the collection bin to selectively cover the opening in a closed position and uncover the opening in an open position. The lid is movable to the open position to empty the contents of the collection bin through the opening while the collection bin remains attached to the housing.
