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.
