Use the sweeper often, try to use it at least 2 to 3 times a week. 2. Keep the sweeper powered on when not applicable. 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. When you need to use it again, install the battery and fully charge it. The battery power that is idle outside will gradually decrease. Generally, The battery can be fully charged once every 3 months to obtain good performance. 5. Keep the brushes of the sweeper clean. If the roller brush of the sweeper is stuck with too much hair and garbage, it will consume more power, and the machine cannot be used lightly. 6. When the battery is in normal operation, if the battery is discharged to 5-10%, it must be shut down or recharged. If the battery is discharged to 0%, the battery will be damaged and its life will be attenuated. 7. Charge the robot vacuum battery for the first time. Due to the instability of voltage and current, when the battery is half charged (sometimes more, sometimes less), the robot vacuum may stop charging the battery. If this happens, don't worry, just remove the battery from the robot vacuum and recharge it. It may take several iterations for a new battery to charge for the first time. Don't worry, this is normal.
