Why can't the Mijia Lint Remover 2 operate after being turned on?

If the Mijia Lint Remover 2 cannot operate after being turned on, please refer to the following steps to troubleshoot:
1. Ensure that the blade cover is installed correctly and is securely tightened. If it is improperly installed, reinstall it firmly.
2. Check that the lint collector is correctly attached. If it is not securely in place or has fallen off, reattach it properly before use.
3. The battery level can be too low to power the device. Make sure to fully recharge the lint remover and then try turning it on again.
4. Verify that the safety contacts between the blade cover and the lint collector are properly connected. If either part is not installed correctly and the safety contacts are disconnected, the device will not start.
5. If the problem persists, please contact the after-sales service center for assistance.
