Using this Bobrick faucet is a breeze. Just wave your hands under the spout, and the concealed sensor will detect your movement and turn the water on. It's hands-free, so it's super hygienic. Remember to use 4 'AA' batteries to power the unit. The in-line filter helps keep the water clean, but it might need a check and replacement every few months. You can adjust how long the water runs and the sensitivity of the sensor to fit your needs. When it comes to cleaning, use a mild soap and a soft cloth to keep the polished nickel finish looking great. Avoid using harsh chemicals that could damage the faucet.
