DETAILED DESCRI PTION OF THE BES T MODES AND PREFERRED EMBODIMENTS OF THE IN VENTION

A broom is often used to sweep and clean floors and is one standard tool for that purpose. Brooms are usually effective for moving loose dirt, dust, or debris; such removal is accomplished through the act of sweeping. It is difficult to sweep debris that is not loose and/or adhered to a surface using a broom. Separate tools or cleaning devices may be required to remove stuck-on- debris. Use of such separate tools or cleaning devices can disrupt the act of sweeping and take additional time to complete over and above such sweeping.
