Auto Flush: No need to touch buttons or handles and never worry about someone forgetting to flush – it’s automatic after each use. AUTO OPEN/CLOSE: Eliminating the need to touch the toilet surfaces, the lid automatically opens and closes when the toilet is approached and departed. DEODORIZER: Highly effective deodorizing automatically takes places inside the toilet bowl both during and immediately after use, leaving no disturbing odors. EWATER+®: EWATER+® cleans the wand and toilet bowl where waste and build up tend to accumulate and create stains that can become permanent. Using no chemicals or cleaning agents, EWATER+ provides peace of mind everyday that microscopic build up has no place to hide. HEATED SEAT: The moment you approach the toilet, the seat begins rapidly warming to a comfort- able temperature. PREMIST®: Using the incoming water supply, a Premist sprays the toilet bowl surface aiding in the elimination of waste approximately 80 percent better than a dry bowl. WARM AIR DRYER: Enjoy the ease and comfort of drying with the temperature adjustable warm air dryer.
