ABSTRACT:
A bag assembly for a vacuum cleaner of the type having a housing defining a bag-receiving compartment, and a lid for closing an opening in the housing above the bag-receiving compartment. The bag assembly comprises a bag having a side wall with upper edge margins defining a bag mouth, and an annular bag support of synthetic resin material. The bag support has an annular wall with a generally vertical central axis, and an annular sealing formation adjacent the top of the wall. The upper edge margins of the bag are stitched to the annular wall of the bag support to provide a seal between the wall and the bag around the mouth of the bag. The bag assembly is placed in the bag-receiving compartment of the vacuum cleaner and the lid moved to a closed position in which the annular sealing formation on the bag support is sealingly engageable with the housing.
