FILTER BAG FOR FLOOR CARE APPLIANCE ABSTRACT A floor care appliance having a filter bag with an inlet chamber accessed by an inlet aperture, and a quie- scent storage chamber connected to the inlet chamber by an opening adjacent the top thereof. The filter bag is formed of filter sheet material as an elongate tubular member having the opposite ends folded and sealed to de- fine an air impermeable seal. An inlet aperture extends into the interior of the tubular member adjacent one end thereof and the tubular member is folded upon itself spaced from the other end thereof with confronting portions of the tubular member being sealed together and including an opening adjacent the fold between the confronting por- tions to maintain an open air path from the inlet aper- ture to the other end of the filter bag. The inlet aper- ture is located so as to create an air flow in the inlet chamber which is curved adjacent the opening between the confronting portions of the tubular member, so that the heavier dirt particles are encouraged to flow through this opening to the storage chamber thus formed for the dirt particles outside of the air flow for the floor care appliance.
