Stihl iMOW Won't Dock: How to Fix It

Q: Why does my Stihl iMOW keep missing the docking station?

This usually indicates a weak perimeter wire signal or debris blocking the charging contacts. Check that the charging station is clean and properly connected, and verify the perimeter wire isn't damaged.

Q: How do I know if my perimeter wire is broken?

Use a multimeter to test continuity between the wire ends at the charging station. No continuity indicates a break. You can also check if the charging station's signal light is blinking, which often indicates wire issues.

Q: Can I use any wire to repair my perimeter wire?

Use only the recommended gauge wire (typically 14-16 AWG) designed for robotic mower perimeter systems. Regular household wire may not provide proper signal transmission and could cause ongoing docking issues.

Q: How often should I clean the charging contacts?

Clean the charging contacts monthly during mowing season or whenever you notice the mower having trouble docking. Grass buildup and oxidation can quickly interfere with proper charging connections.

Q: What if my iMOW charges but still won't dock properly?

If the mower charges when manually placed on the station but won't navigate to dock automatically, the issue is likely with perimeter wire signal strength or wire breaks rather than the charging contacts themselves.

Abstract

When your Stihl iMOW robotic mower won't return to its docking station, it's typically caused by a weak docking signal or a break in the perimeter wire. This prevents the mower from properly navigating back to charge, which can leave it stranded on your lawn.
