Q: The vacuum cleaner won't turn on, even though the battery is fully charged. 

     A：1. Please confirm that you are pressing the power button correctly.
          2. If the vacuum cleaner still does not turn on, try disassembling it and reinstalling the battery, extension tube, floor brush, and any other accessories before attempting to restart it.
          3. If it remains unresponsive after these steps, please contact customer support for assistance with a product replacement.

    Q: After using the brush a few times, it stopped rotating. What should I do?

     A：1. Remove the floor brush roller and check both ends for any hair entanglement.
          2. Thoroughly clean any hair from both ends using a brush tool before reassembling the roller.
          3. If the brush still does not rotate, please reach out to customer support for a replacement.

    Q: When charging the battery, how can I tell when it’s fully charged?

     A：1. The battery is mounted on the vacuum cleaner for charging. During this process, the screen will display the battery percentage, and the small green battery icon will blink. Once fully charged, the numerical display will read 100%, and the green icon will remain illuminated for ten minutes before turning off.
          2. When charging the battery pack separately, a green light will pulse; it will stop pulsing once fully charged, and the green light will remain constant.

    Q: I left it charging overnight, but after just ten minutes of use, the battery dropped to 50%. Is the battery defective?

     A：1. Please make sure that you are using the original adapter that it is included in our packaging. Please use it to charge the battery to ensure the vacuum cleaner operates correctly.
          2. Check if the display indicates that the battery level has reached 100%.
          3. Various settings can be adjusted during use to experience the battery's performance fully.
          4. If issues persist, please do not hesitate to contact customer support. We appreciate your patience and are here to assist you further! 

   Q: My battery charged for four hours, and the vacuum displayed 100% battery life. However, when using it on low speed, it ran out of power in less than ten minutes. Can I get a replacement battery?

     A：1. The default setting when powering on the device is low mode. You can switch between different levels during use to fully experience the battery's performance.
          2. If you encounter the same issue again, please do not hesitate to reach out to customer support.

    Q: I've noticed that I have to clean the brush frequently after just a few minutes of use. It feels excessive, and I would like to initiate a return for a refund.

     A：Please make sure to clean the floor brush thoroughly, ensuring there is no hair residue left behind.
          To maintain the floor brush roller:
          - Detach the roller and inspect both ends for any hair entanglement.

If the problem persists after these steps, please contact customer support to arrange for a floor brush replacement.

          3. Charge the battery pack separately and observe whether the indicator light illuminates.
          4. If the issue continues, please reach out to customer support for assistance.
