Robomow RK4000 Pro: Cannot find / return to base

What this fault means

The mower cannot navigate the perimeter route back to the base.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Charge the mower manually at the base if battery is low.
2. Inspect the perimeter route and base approach.
3. Check for new obstacles or wire changes.
4. Clean charging contacts so docking is recognised.
5. If it reaches the base but does not park, separate docking/charging from navigation diagnosis.
