Abstract
A cleaning head for a vacuum sweeper that incorporates a magnetic flux generator that bathes the area of carpet being engaged by the rotating brush beater in the cleaning head with a pulsing magnetic field. The magnetic flux generator disrupts the static attraction between opposing charged small particles and the carpet fibers to which the small particles are attached to allow the brush beater apparatus in the cleaning head to separate the small particles from the carpet fibers. The dislodged small particles, including allergens, bacteria and mold spores, are removed from the carpet in the air stream created by the vacuum sweeper and captured by a micro-filter filtration system. The magnetic flux field is created with the conventional household current that powers the operation of the vacuum cleaner without requiring the generation of high voltages or an electrostatic discharge from the cleaning head.
