Anker Eufy T29YQA20 dust bag for Omni E28

Anker Eufy T29YQA20 — robot vacuum dust bag for the Omni E28. The bag is the whole point of a self-emptying station: the robot dumps the dust itself and you touch the rubbish once every couple of months. Time to change it when the bag no longer squashes in your hand: a full one chokes the airflow and the station empties the bin for longer and louder than usual.
