Product details
ProTeam's 6-quart backpacks take a cloth outer bag, and part ECC281 is the replacement for the Tailvac, QuarterVac and ProVac, including the Aviator and QuietPro.
The cloth bag holds the machine's shape and catches debris while air passes through the weave. Empty it and it goes straight back to work, which is the whole point. A crew running a backpack daily would otherwise be buying paper bags by the case. What eventually finishes a cloth bag is fine dust embedded deep in the fibers: airflow drops off and washing no longer brings it back.
Wash in cool water, air dry fully, then reinstall. If yours has worn thin at the seams or the collar no longer seals tight against the machine, it is time for a fresh one.
