COMMON CAUSES · RANKED
1
Placed in front of a Virtual Wall MOST COMMON
Starting the robot inside the invisible barrier leaves it nowhere legal to go.
2
Inside the dock's own keep-out zone
j series robots reserve a small area around the dock and refuse to start jobs inside it.
3
Two Virtual Walls facing each other UNCOMMON
Crossed beams create dead zones the robot can start inside by accident.
HOW TO FIX IT
No battery or electrical work involved in this fix.
Move the robot clear
Carry it a couple of meters away from the Virtual Wall or dock and press CLEAN.
Reposition your Virtual Walls
Make sure no two barriers face each other and none points at the dock.
Start jobs from the dock
Docked starts avoid the problem entirely on every series.
