Region scope
This record is currently scoped to UK. Match the SKU and exact model code printed locally; a different code stays Unverified until sourced.
Identify the vacuum
Use the printed series, not the box nickname. Flip the robot or open the app device page and match Roomba Combo j9+.
Replacement steps
- Open the dock bag door, not the robot bin.
- Read the dock name on the station. Plus, Max and Ultra docks split bags.
- Seat the cardboard collar so the door sensor sees a closed bag.
Common mistakes
- Buying a bag for the robot nickname instead of the dock name.
- Using an S8 Max bag rule on a base S8 dock.
- Leaving the cardboard collar unseated so the door sensor stays open.
