Using this Bobrick automatic faucet is a breeze. Just place your hands under the faucet, and the hidden sensor will detect them right away, starting the water flow. The time-out duration can be adjusted according to your needs, so you don't have to worry about the water running for too long. It runs on 4 'AA' batteries, so make sure to replace them when they're low. When it comes to maintenance, the in-line filter helps keep the water clean, but it should be checked and cleaned regularly. Also, be aware of the adaptable sensor range. You can set it to be more or less sensitive depending on your usage. This faucet is designed to be LEED compliant, so it helps save water, which is great for the environment and your wallet.
