Abstract
A unitary liner (36) for use in a dual inner and outer cyclonic vacuum cleaning apparatus (10) is described. The liner has a rigid receiver member (38) that collects dirt separated from the airflow by the inner cyclone (12). The receiver is integrally bonded to a flexible container portion (37) that lays over the inner surface (11D) of the outer cyclone (11) to collect dirt separated from the airflow by the outer cyclone. The container portion (41) can also be a rigid member bonded to a rigid receiver (42). Also, the rigid container portion (45) can provide the outer cyclone and be bonded to a rigid receiver (46). The liner collects separated dirt from the inner and outer cyclones and is easy to remove and replace from the cleaning apparatus by removing the cover (13) which supports the inner cyclone, from the outer cyclone to expose the liner when the vacuum cleaner becomes full of dirt. A liner (130) for a tank type, dual inner and outer cyclonic vacuum cleaning apparatus (110 ) is also described. The tank type liner has a rigid receiver member (131), which collects dirt separated from the airflow by inner cyclone (112) and an integrally bonded flexible container portion (132) th…
