ABSTRACT:
A one piece plastic liner (40) for use in cyclonic vacuum cleaner (10) is described. The liner preferably fits inside of an outer cyclone or container (11) around an inner cyclone (12) and is held in place by the dirt receiver (13), the inner cyclone and the cover (15). The liner collects separated dirt from both cyclones and is easy to remove and replace by removing the cover, the inner cyclone and the receiver when the vacuum cleaner becomes full of dirt.
