Hoover advertises that it's vacuum cleans carpets better than any other leading brand.  That's quite a statement, but it's backed up with an impressive set of features and qualities that are patented and 'trade marked'.  Based on the number of quality features this vacuum has, it is an outstanding bargain.  The patented WindTunnel™ 2 Technology, located in the floor nozzle, forces the rotating brushes and airflow to work in harmony. It lifts and traps the dirt, so it won’t scatter back into your carpet. Dirt ends up in your cleaner, not on your floor.  The Surface Command™ electronic carpet height adjustment and brush shutoff for hard surfaces – move from surface to surface without stopping.  Simply turn the dial for the desired setting.   The Real-Time™ tool system with Tag-Along™ grip makes tool use easy with handle that instantly converts to telescopic wand and Tag-Along™ grip to guide the cleaner.
