A: 1. Please check if the battery has sufficient charge. If the power indicator does not display normally, connect the device to the adapter for charging. Charge for at least one hour before attempting to restart;
2. If the battery is sufficiently charged, the device will have entered protection mode. After switching off the device, wait a short period of time before attempting to restart. During use, frequent short-interval pressing of the power button to achieve rapid on/off operation is not recommended. To protect core components and extend product life, the vacuum cleaner is designed with a start/stop protection mechanism. Rapid and frequent start/stop operations can cause a current surge several times higher than normal, potentially damaging the motor and motherboard, and accelerating battery aging. We recommend waiting at least 5 seconds between turning the vacuum cleaner on or off. This brief interval provides a buffer for the core components, ensuring stable and long-term performance;
3. Please check if the vacuum cleaner has ever suctioned liquid. Past liquid intake may cause the device to fail to power on properly. If such a situation has occurred, please contact the official after-sales service for inspection by a professional engineer.
