Key Features & Innovations


TOTO knew there had to be a way to power the sensor without electrical connections or batteries, a way that would eliminate waste and greatly reduce maintenance and the cost of operation. The answer lay in the power of the water flowing through the faucet. EcoPower faucets don’t need routine battery replacement because they are powered by the force of running water. The water-powered turbine in the EcoPower faucet creates an electrical current that is stored in rechargeable cells to power the Smart sensor system.


ADA Compliant
