Possible Causes

Loose brush bar connection, Worn brush bar end caps, Overheating brush motor, Broken internal wire in cleaner head

Safety first: Turn the robot OFF and flip it over.

Remove and reseat brush bar: Take out the brush bar and reinstall it, ensuring end caps are fully engaged.
Check for overheating: After a few minutes of use, feel the cleaner head. If it is very hot, the motor may be overheating and shutting down.
Inspect cable (if visible): Look for damage to the cable feeding the cleaner head.

If the brush bar continues to stop randomly, replace the cleaner head/brush bar motor assembly.
