The study found that 7 out of 10 users who brushed too hard used pressure sensors to successfully reduce the force of their brushing. Identify areas you missed cleaning to ensure 100% clean coverage If you miss an area while brushing, the app's TouchUp feature will show you that area, allowing you to improve on your second cleaning, ensuring you All thoroughly cleaned.
