How to Fix / Troubleshooting

Safety first: Immediately turn OFF the robot, remove it from the charging base, and allow it to cool. Do not continue using it until inspected.

Step-by-step:

  • Inspect brushes and wheels: Remove main and side brushes, clear all hair and debris. Ensure wheels rotate freely.
  • Check for visible damage: Open the dustbin and inspect for melted plastic or scorch marks near the suction inlet.
  • Smell test: Carefully smell near the suction motor area and main PCB (if accessible) to localize the source.
  • Advanced inspection: Open the robot and inspect the suction motor assembly and main control board for burn marks or melted insulation. Replace any damaged modules.

When to stop: If you see charring or melted parts, do not power the robot again until repaired by a professional.
