failure mode
Roomba i1 Virtual Wall or Keep Out Zone ignored
Symptom: The robot drives through a doorway or into a zone a Dual Mode Virtual Wall — or an in-app Keep Out Zone — is supposed to block, or the barrier seems to do nothing. Likely root causes: Weak or dead AA batteries in the Virtual Wall (most common); Virtual Wall switched off, or set to the wrong mode (Linear vs Halo); Barrier placed poorly — beam not spanning the gap, or robot starting inside the zone; Emitter window dirty or obstructed; beam blocked by furniture; Robot's IR receiver on top of the bumper dirty; App Keep Out Zone drawn in the wrong place, or the Smart Map shifted/was re-created Next steps if owner-level checks fail: Robot still crosses with fresh batteries, correct mode and good placement — the Virtual Wall emitter or the robot's IR receiver may be faulty; test with a second barrier if available, then contact iRobot Customer Care 1-877-855-8593
