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 🙂

  1. I would like a live version of the removal of the battery session because I really love this idea but my thumbs are too big, to remove battery. Please advise.

  2. i can’t get the battery section open, I have tried and so have my friends and family. even used pliers. Help.

  3. My battery won’t come out. I took out the motor, and the battery is stuck; it just won’t come out.
    Please don’t direct me to your instructions. I KNOW HOW to do this and have done it many times. This particular battery is STUCK and I don’t know what to do. I’ve tapped the thing trying to get it to fall out, I’ve tried to pry it out with a paper clip. It’s just not coming out.
