That means it's time to replace the robot's battery. Lithium-ion batteries have a limited lifespan. How to effectively extend the battery famous and maintain high performance: 1. Use the sweeper often, try to use it at least 2 to 3 times a week. 2. Keep the sweeper powered on when not in use. Keep the sweeper on the charging base station. If there is no charging base station, keep the sweeper powered on. If it is not suitable for a long time, such as more than 2 weeks, remove the battery and place it. 3. Place the sweeper in a dry and cool place Avoid exposure to sunlight and keep away from heat sources such as heating equipment, hot exhaust vents, etc. 4. Remove the battery and store it for a long time If you do not use the sweeper for a few weeks or more, remove the battery after it is fully charged and store it in a cool and dry place.
