Roomba i6 Error 6 — Cliff sensors / drop

FM-04

Symptom: Robot beeps six times, reports a cliff/drop, backs up and refuses to continue — even on flat floor, or it won't cross a dark rug. Likely root causes: Cliff sensors are dirty (dust film) and read a false drop; Robot really is at a stair edge or ledge; Very dark or high-gloss floor/rug looks like a void to the IR sensors; Robot lifted/carried while running Next steps if owner-level checks fail: Error 6 persists on clean sensors and normal flooring — a cliff sensor may have failed; contact iRobot Customer Care 1-877-855-8593
