How to Fix / Troubleshooting
Safety first: Turn off the robot and remove it from the dock.
- Power cycle: Leave the robot powered off for 5 minutes, then turn it back on.
- Firmware check: Connect via the Neabot app and check for firmware updates. Apply any available updates fully without interrupting power.
- Factory reset: Perform a factory reset according to the user manual, then reconfigure Wi‑Fi and maps.
- Hardware inspection (advanced): If you are experienced and the warranty has expired, you may open the robot to check for obviously loose ribbon cables on the mainboard. Reseat gently.
- Professional repair: Persistent E19 usually indicates a failing mainboard or sensor board that should be replaced by a technician.
Warning: Opening the robot can void the warranty and expose you to sharp edges and static-sensitive components. Use ESD protection if you proceed.
