Possible Causes

LDS turret blocked or stuck, LDS window dirty or scratched, Navigation camera covered by dust, LDS/camera cable loose or sensor failure

How to Fix / Troubleshooting

Safety first: Turn OFF the robot and remove it from the dock.

Inspect LDS or camera:

  • For LDS models (with a rotating turret on top), gently try to rotate the turret. It should spin freely without scraping.
  • Remove any objects or cables that may have fallen into the turret gap.
  • For camera-based models, clean the camera lens on top/front with a soft microfiber cloth.

Clean sensor windows:

  • Wipe the transparent plastic cover over the LDS or camera to remove fingerprints and dust.

Reset mapping:

  • Use the Proscenic app to clear the existing map (if supported) and start a new full-house mapping run.

Reboot and test:

  • Power cycle the robot and start a cleaning or mapping run in a well-lit environment.

Advanced: If the LDS does not spin at all or E12 appears immediately, the LDS motor or sensor may have failed. Replacement requires opening the robot and is best performed by a qualified technician.
