Roomba full-bin light stays on

Severity: Info — false alarm — the robot may cut runs short but is otherwise fine eijs

DIRECT ANSWER

A full-bin light that stays on after emptying means the bin sensors are coated in fine dust. Six sensors and ports sit between robot and bin — clean them all, then reboot to clear the indicator.

COMMON CAUSES · RANKED

1

Dust film on the full-bin sensors MOST COMMON

Fine dust on the sensors keeps the light on even with an empty bin — iRobot's docs call this out as the standard cause.

2

A sensor port got missed

The system spans sensors on the robot plus inner and outer ports on the bin — six spots total. Cleaning five of six leaves the light on.

3

Stale error waiting for a reboot

Even with everything clean, the indicator can hang around until the robot restarts.

4

Damaged bin or sensor RARE

Washing a bin with electronics, or a hard drop, can kill the sensor circuit. A replacement bin fixes it.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Find all six sensor points

With the bin out, look for the sensor windows inside the robot's bin bay and the ports on the bin's inner and outer walls.

Clean them with melamine foam

Lightly dampened, then dry everything before reassembly.

Reboot to clear the indicator

Reinstall the bin and hold CLEAN until you hear the reboot tone.

Light back next run? Replace the bin

A persistent indicator with spotless sensors means the bin's sensor circuit has failed.
