Identify the vacuum

Use the printed series, not the box nickname. Flip the robot or open the app device page and match Roomba j9+.

Replacement steps

1. Open the dock bag door, not the robot bin.
2. Read the dock name on the station. Plus, Max and Ultra docks split bags.
3. 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.
