To address weak oscillation and poor cleaning performance with the Xiaomi Oscillation Electric Toothbrush, please consider the following:
1. Do not apply excessive pressure while brushing. If the pressure is too strong, the vibration of the toothbrush will weaken. The toothbrush has three modes, so you can choose the one that suits you best.
2. Cleaning effectiveness can vary depending on usage habits, selected mode, and brushing duration. Choose a mode that fits your routine.
3. Remember to hold the bristles at a 45-degree angle to your gums and move the brush slowly to cover each tooth, including the inner surfaces and gaps.
4. Follow the 30-second zone change reminder to ensure every tooth is thoroughly cleaned.
5. If the brush head has been used for more than 3 months, the bristles can become worn or deformed, reducing cleaning effectiveness. It is recommended to replace the brush head in time.
