Ultrasonic U-Shape Toothbrush for Adults

The Waterpik Martenit AY-681-08 is an ultrasonic automatic toothbrush designed for adults who want a hands-free cleaning experience. Its U-shape brush head matches the dental arch to contact teeth and gums from all sides using high-frequency sound vibration. The device is made from food-grade silicone and ABS for water resistance and daily reuse. It suits home and travel use with a compact, portable design.

Four Cleaning Modes with 30-Second Timer

A single specification decides fit: the brush offers four selectable modes — powerful deep cleaning, medium daily cleaning, gum care massage, and whitening mode that works with whitening gel. A built-in 30-second automatic timer controls each cleaning session, while a separate 15-minute cycle supports whitening. The 6 W vibration motor drives the 3D cleaning action across every mode.

Wireless Charging Base with Week-Long Battery

The toothbrush charges wirelessly on its included base, reaching a full charge in three hours and lasting roughly one week per charge. A low-battery alert prevents unexpected power loss. The package supplies the main body, charging base, USB cable, four brush heads and a manual. No wall adapter is included, so a standard USB power source is required.

Questions about this item

How long does the 30-second automatic timer run before the brush stops?

The built-in timer stops the cleaning cycle after 30 seconds, giving a quick full-mouth clean each session.

What does the wireless charging base actually deliver to the handle?

The base charges the internal battery at DC 5 V input; a full 3-hour charge provides about one week of regular use.

Will the 2.36 × 0.98 × 4.33 inch U-shaped head fit in a standard travel washbag?

At 60 × 25 × 110 mm the main body is compact enough for most toiletry bags, and the silicone brush head folds flat for packing.
