Operating
Once the battery is installed, your robot vacuum cleaner is ready for operation. The battery will charge when the vacuum is placed on its charging base or plugged in directly.

- Always use the original charging base or power adapter provided with your robot vacuum cleaner.
- Avoid completely draining the battery frequently, as this can reduce its overall lifespan.
