Using the Womanizer Duo 2 is easy. First, make sure it's fully charged. You can connect it to a power source with the USB cable using the magnetic charging pins. Once charged, turn it on. You'll feel a haptic feedback. Choose your preferred intensity level from the 14 available and a vibration pattern from the 10 options. You can use the Pleasure Air clitoral stimulator and the G - spot vibrator together or separately as you like. When you're done, simply turn it off. As for maintenance, since it's waterproof (IPX7), you can rinse it under water. Use a mild, body - safe cleaner to clean it. Keep it in a cool, dry place. Remember, the Smart Silence function will turn it off if it's not in contact with your skin, so be aware of that during use. Also, make sure to use body - safe lubricants with it for a better experience.
