HOVER VACUUM CLEANER AN IMPROVED SELF-PROPULSION HOVERING VACUL1111 CLEANER FOR DOMESTIC OR INDUSTRIAL APPLICATION DESIGNED WITH AIR OUTLETS WHICH ARE PREDISPOSED SYMMETRICALLY ALONG TILE LONGITUDINAL AXIS OF THE UNDERSIDE OF THE CASING FOR DIRECTING MORE AIR TO TILE FRONT AND BACK DIRECTIONS OF THE VACUUM CLEANER TO ACHIEVE A MORE EVEN DISTRIBUTION OF' AIR UNDERNEATH THE VACUUM CLEANER TO REDUCE JUDDERING OR ROCKING EFFECTS. THE UNDERSIDE OF THE CASING HAS A CURVE LIP SURFACE PREDISPOSED SYMMETRICALLY ALONG THE LONGITUDINAL AXIS OF TILE UNDERSIDE OF THE CASING FOR BETTER RETENTION OF AIR TO ENHANCE THE HOVERING EFFECT. IN ANOTHER EMBODIMENT OF THE PRESENT INVENTION, THERE ARE AIR DISTRIBUTION CHANNELS PREDISPOSED SYMMETRICALLY OIL BOTH SIDES OF' THE UNDERSIDE OF THE CASING ALONG THE LONGITUDINAL AXIS OF THE UNDERSIDE OF THE CASING, SAID AIR DISTRIBUTION CHANNELS ARE IN COMMUNICATION WITH THE AIR OUTLETS FOR DIRECTING MORE AIR TO THE FRONT AND BACK DIRECTIONS OF TILE VACUUM CLEANER.
