A bagless vacuum cleaner having a chasse, an air blower and a dust extraction and collection unit is provided. The dust extraction and collection unit has an easily removable inlet chamber and an easily removable outlet chamber. The inlet chamber is substantially cylindrical, and the outlet chamber is disposed concentrically within the upper portion of the inlet chamber. Duct work within the chasse conducts air from the base of the chasse and into the inlet chamber in tangential fashion, such that air swirls about the inside walls of the inlet chamber. Air within the inlet chamber is then allowed to escape from the inlet chamber into the outlet chamber via a plurality of small holes disposed in the side walls of the outlet chamber. Air within the outlet chamber is exhausted to the blower via a top wall opening in the outlet chamber. The outlet chamber contains a vertical, cylindrical filter disposed concentrically within the outlet chamber and a second, planar filter disposed across the top wall opening of the outlet chamber. |
