8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Robot does not turn on. | Low battery; not properly docked. | Ensure robot is fully charged on the station. Check power connection to the station. |
| Robot cannot connect to Wi-Fi / frequently loses connection. | Incorrect Wi-Fi password; 5GHz network; weak signal. | Ensure you are connecting to a 2.4GHz network. Re-enter Wi-Fi password. Move station closer to router or consider a Wi-Fi extender. |
| Robot gets stuck frequently. | Obstacles (cables, small objects); high thresholds. | Clear floor of obstacles. Use virtual walls/no-go zones for problematic areas. The robot can overcome obstacles up to 20mm. |
| Poor cleaning performance. | Full dustbin; clogged brushes/filters; low suction setting. | Replace dust bag. Clean main brush, side brushes, and filters. Increase suction power in the app. |
| Auto-emptying station is very loud. | Normal operation during dust collection. | This is normal during the emptying process. Consider scheduling emptying during times when noise is less disruptive. |
