Lever power

The center inset shows a belt-driven hay press; the lower two show a horse-powered reversible lever power press and a horse-powered continuous power press.

Features include a vandal-resistant pressure release lever, lever power return spring, choice of lever handle styles, and low current draw.

Attached to a WC ceramic, the seat doesn't require electricity -- instead, the spray is operated by a side lever powered only by water pressure, putting the control at your fingertips for an effective but gentle cleaning experience.
