COMMON CAUSES · RANKED

Physical blockage on the route MOST COMMON

Closed doors, laundry baskets or furniture cut the corridor the robot planned to use.

Virtual Wall across the path

A powered barrier between rooms blocks the route as surely as a door.

Disconnected Smart Map UNCOMMON

If the map shows rooms as separate islands, the robot can't plan a path between them.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Walk the route yourself

Follow the robot's path from dock to target and remove every obstacle you find.

Power off blocking Virtual Walls

Check for barriers standing between the dock and the target room.

Inspect the Smart Map

Confirm all cleaning areas connect on the map. If the layout looks wrong, remap.

Reboot to clear the error

Hold the power or CLEAN button about ten seconds, restart, and retry the job.
