A hovering vacuum cleaner comprising a base having a top and a bottom, the vacuum cleaner including a drive unit for powering a fan assembly, said drive unit being fixed to the base proximate the top thereof, a dust collection chamber having an inlet and containing a filtering assembly for collecting dust during the course of normal vacuuming, a filter assembly being removably secured within said dust collection chamber adjacent said drive and said fan assembly, said base having disposed proximate the bottom thereof an air outlet allowing air to pass from the fan to the bottom of said base, a hovering channel disposed proximate the bottom of the base in communication with said air outlet and for providing the lift of said hovering vacuum cleaner, said hovering channel being disposed on the bottom of said base in an arch, said base also including a perimeter portion to help retain the air in said hovering channel, said dust collection chamber having the inlet being adapted to receive in use a nozzle end of a vacuum cleaner hose, said nozzle end having an air outlet disposed substantially perpendicular to the direction of extension of said nozzle and thereby discharging in use turbulent air directed toward said filtering unit, so as to generate cyclonic action in said dust collection chamber and to wipe the surfaces of said filtering unit and to keel) both the air and the dust in motion and thereby minimize the likelihood of said filter assembly fouling and thereby reducing the efficiency of said hovering vacuum cleaner.
