COMMON CAUSES · RANKED

Robot started on top of a strip MOST COMMON

Starting a mission while parked on the boundary strip blocks the robot immediately — the official fix is simply to relocate it.

Strip laid across the robot's only route

A strip across a doorway the robot must pass strands it against the barrier on every mission — reroute the strip.

Another magnet source nearby RARE

Speaker magnets and magnetic door stops against the chassis can read like a boundary strip.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Move the robot away from the strip

Set it down on open floor at least half a metre from any boundary strip and restart.

Reroute the strip if it repeats

Lay strips so the robot meets them side-on during cleaning and never has to start a mission on top of one.

Check for stray magnets

If there is no strip nearby, look for magnetic door stops, speakers or toys along the robot's path.
