ABSTRACT:
A disc-shaped shroud having a cylindrical section (50c, 132) adjacent to an inner surface (15b, 111b) of a cyclonic container (15, 111) including a preferred combined shroud and disc unit (50) for use in a dual inner and outer cyclonic vacuum cleaner (10) is described. The combined shroud and disc unit fits on the outside surface (20c) of the inner cyclone (20) and aids in removal of dirt and fibrous matter from the airflow in the outer cyclone (15). Improved airflow between the outer cyclone (15) and inner cyclone (20) is achieved because of the shroud and disc unit (50).
