failure mode
Roomba i2 Won't power on / completely dead
Symptom: Pressing/holding CLEAN does nothing — no lights, no sound, no movement. Likely root causes: Battery fully flat / deep-discharged; Battery disconnected or pull-tab still fitted; Charging never worked (dirty contacts / dead base — see FM-11/FM-14); Battery at end of life; Robot left off the charger for months Next steps if owner-level checks fail: Dead even with a genuine charged battery, clean contacts and a powered base — internal fault; contact iRobot Customer Care 1-877-855-8593
