Abstract
There is disclosed a vacuum cleaner bag assembly for an upright vacuum cleaner comprising a flexible, air-permeable, outer bag having an upper end adapted to be attached to a handle of a vacuum cleaner. The other end of the outer bag has an open mouth attached to an open mouth of a dirt-collecting box. The dirt-collecting box has a suction inlet opening and also a suction outlet opening which comprises its open mouth. A tube closes the open mouth of the box and is in fluid communication with the box and extends toward the top of the outer bag. A disposable inner bag is provided within the outer bag and has an inlet opening in fluid communication with the tube. A vacuum cleaner provided with the bag assembly may be operated as a vacuum cleaner with a disposable bag with all of the foregoing elements in place, or as an air-permeable outer bag filter vacuum when the tube and disposable bag are removed.
