Abstract: Embodiments of the invention generally include a contamination housing assembly and bag for use therein. In one embodiment, a contamination housing assembly includes a housing having an inlet, outlet, and access port. A bagging ring is coupled to the housing and circumscribes the port. A door is provided for covering the port. A bag indicator is coupled to at least one of the containment housing or door and is visible, when in a first position, from an exterior of the containment housing when the door substantially covers the bagging ring. In yet another embodiment, a bag for use with a containment housing is provided. The bag has an open end configured to engage with a bagging ring. The bag includes at least one of a strap or a RF readable tag.
Abstract: A removable dust collector for use in a dust compartment of a vacuum cleaner is provided and includes a holder that maintains the dust collector in an operating position, and a locking member that is placed in a locking position when the dust collector is removed. A cover of the dust compartment is prevented from closing and is placed in a release position when the dust collector is in an operating position. The locking member is maintained in its release position either by means of a filter bag inserted into a carrier or by an actuating member associated with the dust collector.

Abstract: An improved filter bag is provided for swimming pool cleaners and the like particularly of the type designed for travel along submerged pool surfaces to dislodge and collect debris. The filter bag is formed from an elongated stretch of porous fabric, such as nylon mesh, folded upon itself to define conforming left and right sidewalls joined by front and rear seams and a seamless upper end. The lower ends of the sidewalls are secured to a mounting collar which cooperates therewith to define an open mouth for entry of debris into the bag and means for attachment about the discharge end of a pool cleaner suction mast. Water and debris are drawn by the cleaner through the mounting collar into a primary flow chamber within a forward region of the filter bag and separated from a rear collection chamber by an upstanding divider seam which terminates below the seamless upper end of the bag.
Abstract: A collecting bag for collecting dusts having an air permeable bag body made of a cloth and provided at its one end with a connection opening for connection to a passage of the dust laden air and at its other end with a discharge opening through which the dust content of the bag is taken out. A pair of opposing plate members are jointed to the opposing peripheral edges of the discharge opening of the bag body so as to cooperate with each other in opening and closing the discharge opening. One of the plate members may be provided with a hook which engages a suitable member fixed to the bag in the closed state of the discharge opening.
Abstract: A vacuum cleaner filter bag is made of a porous sheet of material which permits penetration and flow therethrough of air. The bag is generally horseshoe-shaped and has a comparably shaped internal cavity. The bag has two tubular leg portions and a tubular connecting portion between the leg portions. An air inlet opening is provided on the connecting portion for admitting a stream of air under pressure into the cavity and an opening, which permits removal of accumulated debris but which is closed during use of the bag, is also provided on the connecting portion. The air flow between the air inlet opening on the vacuum cleaner housing and the inlet opening of an exhaust motor situated within the vacuum cleaner housing generally tends to primarily penetrate or flow through a wall portion of the bag disposed between the respective inlet air openings.
