Toto is a pioneer in bathtub toilets, which was introduced to the U.S. market as early as 1993. The difference between the latest models of smart toilets is that the patented technology used to keep organic waste (whether visible or not) comes from "adhesion," which means less bowl cleaning tasks. First of all, its ewater + uses water supply to pre wet the surface with a mist, which helps prevent 80% better adhesion than a dry bowl.

After washing the intelligent toilet, ewater + releases the mist of slightly acidic electrolyzed water. Finally, the bowl's hydrotect glaze is also constantly contaminated: the integrated ultraviolet light on the seat cover touches the hydrotect coating to catalyze a process to decompose organic matter. The model also offers a smart toilet Foundation: a cleaning system, sensor driven covers that open and close when you enter and leave the room and wash hands-free. This high-end model can only use less than 1kg of water per flush.
