Why can't the Mijia Lint Remover 2 be turned on?

If the Mijia Lint Remover 2 can not be turned on, please refer to the following information:
1. Make sure the device has sufficient power. If the battery is depleted, connect it to a compatible charger and charge it for a while before trying again.
2. The lint remover has built-in safety protection. If the blade assembly or blade cover is not installed properly, the device will not power on. Please reinstall them securely and try again.
3. Excessive lint accumulation inside the blade area can trigger protection mechanisms. Clean the blade assembly and lint collector thoroughly.
4. If the device was used continuously or under heavy load, it can have activated overheat protection. Let it cool down for several minutes, then try powering it on again.
5. Ensure the power button is pressed correctly and is not stuck or damaged.
6. If none of the above solutions resolve the issue, please contact after-sales support for assistance.
