Possible Causes

Cliff sensors dirty or blocked, Robot partially resting on an object, Faulty drop sensor, Firmware miscalibration

How to Fix / Troubleshooting

Safety: Turn the robot OFF before cleaning sensors.

  • Place on flat surface: Ensure the robot is on a hard, level floor with all wheels fully supporting its weight.
  • Clean cliff sensors: Turn the robot over and locate the downward-facing sensors near the front. Wipe them gently with a dry microfiber cloth.
  • Check for stuck wheels: Make sure both drive wheels and the front caster wheel move freely and are not jammed in the raised position.
  • Restart the robot: Power ON and start a cleaning cycle. If the error appears immediately, a drop sensor may be faulty and require replacement.
