Robot vacuum starts but shuts off after a few minutes, returning to the dock or powering down unexpectedly.

Safety first: Turn off the robot and let it cool if it feels warm.

• Full charge cycle: Charge the robot uninterrupted for at least 4–5 hours, then run a full cleaning cycle to calibrate the battery gauge.
• Reduce load: Clean main and side brushes, filters, and wheels to reduce mechanical resistance.
• Battery age check: If the robot is more than 2 years old and runtime is under 20–30 minutes, replace the battery pack.
• Charging contacts: Clean the charging contacts on both robot and dock to ensure full charging.

Warning: Do not continue to run a robot with a failing battery until it shuts off completely; deep discharges can further damage the pack.
