Setup
Charging the Toothbrushes

Attaching Brush Heads
Align the brush head with the metal shaft on the toothbrush handle. Gently push down until the brush head clicks securely into place. Ensure a firm connection before use.
Operating
Power On/Off and Mode Selection
Press the power button to turn the toothbrush on. Press the mode button repeatedly to cycle through the available brushing modes:
- Clean: Standard brushing mode for daily plaque removal.
- Whiten: Designed to help remove daily surface stains for a brighter smile.
- Massage: Delivers vibrating microbursts to gently stimulate gums.
The toothbrush will remember your last used mode for convenience.

Smart Timer
Each toothbrush features a built-in smart timer. It will pause briefly every 30 seconds to signal you to move to a different quadrant of your mouth, ensuring a thorough cleaning. The toothbrush will automatically shut off after 2 minutes, indicating the completion of the recommended brushing time.
Sonic Technology
The 40,000 VPM (Vibrations Per Minute) motor provides powerful sonic vibrations that effectively remove up to 10 times more plaque than a manual toothbrush, reaching deep between teeth and along the gumline.

Maintenance
Cleaning the Toothbrush
After each use, rinse the brush head thoroughly under running water. Wipe the handle with a damp cloth. Do not submerge the entire toothbrush handle in water, as it is only IPX7 waterproof (protected against temporary immersion).
Replacing Brush Heads
For optimal hygiene and performance, it is recommended to replace brush heads every 3 months, or sooner if the bristles become frayed. Simply pull the old brush head off the handle and push a new one into place.

Travel
Travel Convenience
The Aquasonic Duo comes with two convenient color-coded hard-shell travel cases. These cases are made of BPA-free plastic and provide space for the toothbrush handle and two brush heads, making it easy to take your oral care routine on the go. The 30-day battery life ensures you can travel without needing to bring the charging dock.
