Possible Causes

How to Fix / Troubleshooting

Safety: Turn the robot OFF.

  • Check bumper movement: Gently press the front bumper in and release. It should move freely and spring back evenly across its length.
  • Clear obstructions: Look for lodged debris (toys, cords, carpet edges) between the bumper and the body. Remove anything found.
  • Clean bumper gap: Use compressed air or a soft brush to clean the gap where the bumper slides.
  • Tap to free switches: Lightly tap along the bumper to free any stuck internal switches.
  • Power cycle and test: Turn the robot back on and start a cleaning cycle.

If the bumper feels loose, uneven, or the error persists, the bumper switch assembly may need adjustment or replacement.
