Step 1: Remove old brush head
Grip the head and handle in opposite hands, bristles facing away from you. Place your thumb on the dots, then gently pull the head off in a slight arc motion (don’t snap it directly backwards).
Step 2: Remove motor and battery
Pull the motor out by lifting it by the wings or using the thumbnail notch. Once it’s removed, tip the handle over and tap out the battery.
Step 3: Clean brush handle
Lightly wet the bristles on your old brush head, and use it to gently scrub away any dried toothpaste from the top white portion of the handle.
Step 4: Replace motor and battery
Drop in a new AAA battery or a fresh rechargeable negative end first, then slide the motor back in (it will spring up slightly).
Step 5: Apply fresh brush head
Push on your new brush head until it’s flush with the handle and you hear a dull click. Press the “q” to test, then you’re set. Happy brushing 🙂
