The Rubbermaid Commercial AutoFlush Toilet System creates a cost-effective, touch-free flushing system for high-traffic washrooms. Eliminating the need for flush handles, it improves washroom hygiene and installs in minutes. With a daily flush option that prevents sewer gas buildup, it offers an audio tone to indicate low battery life and an adjustable sensor range. With four included "C" batteries that last up to three years or 60,000 flushes, this touchless toilet system has an angled lens sensor design to operate even when the seat is raised and has a fail-safe courtesy button to eliminate the source of odors.
