Abstract
The present invention relates to upright and cannister vacuum cleaners. The improved vacuum cleaners utilize toroidal vortex technology to provide efficient airflow in a sealed system. The sealed system prevents dust from escaping into the atmosphere and retains kinetic energy of flowing air. The present invention is also quieter, lighter, and simpler than conventional designs.
