No, Willo is not a vibrating mouthpiece. Willo is a toothbrushing robot that has a non-vibrating supple mouthpiece covered with nylon bristles that you insert inside your mouth. When you launch a cycle, the pumps inside Willo make the mouthpiece contract around all surfaces of your teeth and then relax. The combined action of the contraction/relaxation of the mouthpiece and the consequent movements of the bristles onto the teeth surfaces is how Willo scrubs plaque free from your teeth and carries it away into your sink, automatically!
