Abstract
Disclosed are improved vacuum cleaning apparatus that utilize toroidal vortex air flow in order to establish a pressure differential capable of attracting debris. These systems and its derivatives are essentially closed systems; there is no constant intake and exhaust of fluid. Included in the debris collection apparatus is a compaction means that captures debris caught in the toroidal vortex flow, and deposits it in a desired chamber.
