Robot vacuum runs for only a short time (e.g., 5–15 minutes) before returning to dock or shutting off.

Safety first: Turn the robot OFF and remove from dock.

• Full charge cycle: Charge the robot fully, then run it until it returns to dock. Repeat once to recalibrate battery estimation.
• Check battery age: If the robot is more than 2–3 years old, the battery is likely worn.

Solution: Replace the battery pack with a genuine Ecovacs-compatible battery of the same voltage and capacity.
