Is the Colgate E1 Toothbrush waterproof?

Apple has begun selling the Colgate E1 Toothbrush through its online store. It is a $99 smart toothbrush that works with an app to monitor your oral health. The built-in AI can detect the orientation of the brush to build a personal brushing profile and offer recommendations to improve your brushing techniques.

The Colgate E1 toothbrush handle is sealed and is wrapped in a waterproof casing. It is designed to be cleaned by rinsing under water. The Colgate Warnings page notes that the charger is not waterproof, and users should contact Colgate-Palmolive if it is dropped in water or becomes damaged.
