<p>A cyclonic vacuum cleaner (10) having a primary reservoir (14) into which air is drawn by a fan (36) through an air intake (12) and into a cyclone tube (16). Intake air exhausts through an open end of the cyclone tube (16) into the primary reservoir (14) where it is drawn against the inside wall of the primary reservoir (14) creating a cyclone. Air is drawn up through the center of the cyclone through a wet and dry filter (18) into a riser intake (20). Air is drawn through the riser (22) and enters a filter housing (30) holding a bag filter (32) and a HEPA filter (34). Air is exhausted from the apparatus through air outlet (40) following passage through the HEPA filter (34).</p> |
