How to Fix / Troubleshooting
Safety first: There is no electrical hazard in normal use, but do not open the robot casing.
- Reboot robot and router: Turn the robot OFF and unplug your Wi‑Fi router for 30 seconds. Power the router back on, wait for full connectivity, then power the robot on.
- Forget and re‑add device: In the Dyson app, remove the robot, then follow the pairing instructions again, ensuring you use a 2.4 GHz network if required.
- Check signal strength: Move the dock closer to the router and avoid thick walls or metal cabinets between them.
- Firmware update via USB/service (if available): Some models may allow service firmware updates; contact Dyson support.
If F11 persists and the robot cannot be discovered by any device, the internal Wi‑Fi/communication board may need replacement.
