Ultrasonic Toothbrush with U-Shape Design

The Waterpik RONGCHUANG AY-681-RS12 is an ultrasonic automatic toothbrush built for adults who want hands-free daily cleaning. Its U-shape head matches the dental arch to contact teeth and gums from every angle. Four selectable modes cover powerful brushing, comfortable cleaning, gum massage and whitening. The device suits home and travel routines alike.

Food-Grade Silicone Body and Wireless Charging

The handle uses food-grade silicone and ABS for full water resistance and easy rinsing after each use. A wireless charging base delivers a week of operation from a three-hour charge, and a low-battery indicator prevents unexpected shutdowns. The compact 2.36 by .98 by 4.33 inch form fits a toiletry bag without taking much space. Buyers who need a second brush head in the box will not find one here.

30-Second Cleaning Cycle with 1500 mAh Battery

A single 30-second cycle completes the automated brushing routine, while a separate 15-minute whitening mode works with optional gel. The 1500 mAh cell powers the 6 W vibration motor at 3.7 V through the USB charging cable supplied. Users who prefer longer variable brushing intervals should note the fixed timer cannot be adjusted.
