Abstract
The present invention aims at improving pool cleaners. The improved pool cleaners utilize toroidal vortex technology to provide efficient fluid flow in a sealed system. The sealed system prevents dirt from escaping into surrounding fluid and retains kinetic energy of the flowing fluid. The present invention is also quieter, lighter, and simpler than conventional designs.
