A vacuum cleaning system includes a housing defining an inlet and an outlet, a motor connected to the housing and configured to generate air flow through the housing from the inlet to the outlet, and a debris container received within the housing in a first direction. The debris container includes a knob that is rotatable about an axis and includes a first cam and a second cam. Rotation of the knob about the axis causes the first cam to engage the housing and thereby move the debris container in the first direction, and causes the second cam to engage the housing and thereby move the debris container in a second direction.
