Sloan’s G2/ECOS line of battery-operated flushometers features an improved battery life from three years to six. Other improvements include a self-adaptive sensor that adjusts to any building environment and a new infrared sensor, which improves the ability to ignore optical noise from the environment. All model numbers and repair parts will remain unchanged. The changes are all internal to the electronics and outside of some label changes, the product itself will look identical to the current model.
