Bissell 3387 filter for FeatherWeight

Bissell 3387 — cordless stick vacuum filter for the FeatherWeight. A stick vacuum filter clogs long before the cleaning result gives it away: the motor rises in pitch and the bin holds less after the same run. Rinsing extends its life but does not replace it — the fibre mats down over time and part of the fine dust comes back into the room with the exhaust air.
