Use foot-operated mechanical systems instead of powered no-touch devices
Friction: Foot pedals never run out of batteries.
Why this matters
Infrared sensors on faucets and bins are notorious for not detecting hands or activating randomly. They require batteries and motors. A foot pedal provides 100% reliable, hands-free operation with zero power.
Good Sense principle
Reliability creates trust. Use the simplest tool that solves the problem.
