Clear a Roomba full-bin light after emptying the bin
Clean the complete six-sensor path and reboot once before treating a persistent full-bin indicator as a service fault.
Direct answer
The shortest reliable path.
Empty the bin, then clean all six parts of the full-bin sensing path: the two sensors on the robot plus the inner and outer sensor ports on both sides of the bin. A bin that looks empty can still report full when dust blocks those optical paths. Reinstall the dry bin and reboot the robot once. If the indicator remains after all six locations are clean, contact iRobot.

Full-bin sensors on the robot
This official image locates the two robot-side sensors; these are only two parts of the six-point optical path.
- Look for
- Find both opposed sensor windows in the bin bay and remove surface dust without pushing tools into them.
- Applies to
- Wi-Fi-connected Roomba models covered by iRobot’s full-bin indicator cleaning article.
Inner full-bin sensor ports
The highlighted inner ports must remain optically clear even when the debris chamber itself looks empty.
- Look for
- Inspect both inner ports for a dusty film or compacted debris that blocks the sensor path.
- Applies to
- The bin design illustrated in iRobot’s Wi-Fi-connected Roomba full-bin indicator article.
Outer full-bin sensor ports
The outer ports complete the bin-side optical path and need cleaning along with the inner ports and robot sensors.
- Look for
- Check both exterior sides of the bin instead of cleaning only the surfaces visible inside the chamber.
- Applies to
- The bin design illustrated in iRobot’s Wi-Fi-connected Roomba full-bin indicator article.

Procedure
Do this in order.
- 01
Empty the debris bin completely
Remove the bin, open its door, discard all debris, and clear material packed against the door or filter area.
- 02
Clean all six sensing locations
Wipe the two full-bin sensors on the robot and the inner and outer sensor ports on both sides of the bin until each optical path matches iRobot’s clean examples.
- 03
Reinstall the dry bin
Confirm the bin, door, ports, and filter area are dry and unobstructed, then seat the bin completely.
- 04
Reboot once and reassess
Use the official reboot method for the exact robot model, then check whether the full-bin indicator returns.
Diagnostic matrix
Read the result, not the guess.
| What you see | Check next | What it means |
|---|---|---|
| The light clears after six-point cleaning | Run a short cleaning mission and recheck the bin normally. | Dust in the optical sensing path was the likely cause. |
| The bin is empty but one port remains visibly dirty | Finish cleaning that port before rebooting again. | The official cleaning prerequisite is not yet complete. |
| The light returns immediately after complete cleaning and reboot | Contact iRobot with the charged robot and serial number. | The supported user-cleaning path did not resolve the fault. |
Stop conditions
Know when not to keep changing things.
- Do not assume an empty bin proves the optical sensor path is clear.
- Do not reinstall wet washable components or push tools into sensor openings.
- Stop repeating reboots after one complete clean-and-reboot cycle; use iRobot Customer Care for a persistent indicator.
