ABSTRACT:
This disclosure concerns primarily the filter dirt-collecting bag for a vacuum cleaner having a motor and motor-driven fan in a housing. The outlet from the fan projects outwardly and usually upwardly from the housing and is removably connected to the bottom of the flexible bag for collecting the dust, which bag substantially and preferably completely covers the housing like a pillow to muffle the mechanical noise from the motor and fan. Inside the bag is a tube, which may be non-porous and flexible, connected at its lower end directly to the fan outlet at the bottom of the bag and at its upper end to the top of the bag. Adjacent the upper end of this tube is connected an outwardly and downwardly extending tubular extension, spout or nozzle, for muffling the air noise from the fan and directing the dirt toward the bottom of the bag.
