Abstract
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, the cover prevents debris from leaving the collection chamber through the inlet opening. The wall of the collection chamber moves when negative pressure is applied to the collection chamber, and the wall movement moves the cover from the inlet opening, allowing the debris-entrained air to enter the collection chamber. In some embodiments, the moving part of the wall is an air filter.
