Possible Causes

How to Fix / Troubleshooting

Safety first: Turn off the robot and remove it from the Home Base.

Steps to resolve:

  • Clean brushes and wheels: Thoroughly clean the main brushes, side brush, and wheel wells to reduce load.
  • Check battery health: Fully charge the robot and observe if the behavior improves. Replace the battery if it is old or swollen.
  • Soft reset: Perform a soft reset via the CLEAN button sequence.

When to replace parts: If the robot still shuts down quickly, a motor module (brush, wheel, or vacuum) or the main board may be failing and should be tested and replaced as needed.
