Using this water faucet is easy. Just wave your hand in front of the sensor, and the water will start flowing. It works with both battery and AC power. If you use batteries, make sure to replace them when they run out. To keep it looking great, clean the spout and sensor housing regularly with a soft cloth and mild cleaner. Avoid using abrasive materials that could scratch the polished finish. And that's all there is to it! Enjoy the convenience of your new hands-free water faucet.
