A full-bin message can refer to debris the robot senses in a bin, a bin that is not seated, or a bin type that the robot does not recognize. Emptying the bin once more may not address the detection problem. Record the exact robot model, bin type, alert wording, and whether the alert appears on the robot or in the app. These checks are deliberately limited to two iRobot product groups with published support guidance.
Roomba 700 series: use its bin-full sensor instructions
For a Roomba 700 Series that still shows the full-bin indicator after emptying, iRobot says to hold CLEAN for about 10 seconds until rSt appears and a tone sounds, then clean the inside sensor walls with a dry microfiber or soft cotton cloth. Reinstall the bin before running the robot. This sequence is limited to the 700 Series; if the indicator remains on, contact iRobot rather than replacing a sensor based on the light alone.
Combo i5, i5+, j5, or j5+: check the bin type
For the listed Combo i5/i5+, j5, and j5+ bin-detection state, iRobot gives a specific cleaning path: clean the head and bin, remove the filter, rinse the bin and door only as instructed, let all rinsed parts air-dry completely, wipe the bin-full sensors, and clear the brushes and vacuum path. Make sure the bin is correct for the task and seats fully. If the named Combo error remains, its support page describes holding CLEAN for 10 seconds to reboot. Follow that page for the exact Combo model and message; do not force a bin or generalize the sequence to other Roombas.
Keep dock collection separate from robot detection
A robot can detect its bin correctly but still fail to empty it at an auto-empty station. If the robot’s bin is emptying incorrectly, see dock emptying diagnosis. If the bin fills during cleaning because debris is not being picked up, see brush and pickup diagnosis.
Stop if the bin or its latch is cracked, the robot has liquid inside it, or the alert returns with heat, an unusual odor, or electrical damage. Do not bypass a bin sensor or alter a safety interlock; contact the manufacturer’s support channel for the exact model.
