How to Fix / Troubleshooting
Safety first: No electrical disassembly is required for basic troubleshooting. Only open the robot if you are experienced and the warranty has expired.
- 1. Check network compatibility:
- Ensure your router broadcasts a 2.4 GHz network (Xiaomi robot vacuums typically do not support 5 GHz only).
- 2. Reset Wi‑Fi on robot:
- Press and hold the Wi‑Fi or Home button combination as per your model's manual until you hear a Wi‑Fi reset prompt.
- 3. Re-add device in app:
- Open Xiaomi Home, tap +, and follow the pairing instructions.
- 4. Move closer to router:
- Place the dock and robot within a few meters of the router during setup.
- 5. Advanced inspection:
- Open the robot and check that the Wi‑Fi antenna cable is connected to the mainboard and antenna pad.
- If the Wi‑Fi chip is integrated and defective, the mainboard may need replacement.
