The WASHLET®+ S550e features Toto's technologically advanced EWATER+® system which uses electrolyzed water generated by a technologically advanced process, transforming the water into a safe and powerful compound. By misting the bowl after every use and cleaning the wand, EWATER+®technology helps to keep your toilet bowl clean and hygienic without any extra harsh chemicals. The PREMIST® function sprays the bowl with water before each use, preventing waste buildup and keeping the toilet bowl clean. The Toto® WASHLET®+ S550e is fully automated, including an illuminated remote control with 5 spray settings, auto open and close lid, heated seat and instantaneous water heating. The Drake® features Toto's TORNADO® flush®, a rimless, hole-free rim design with dual-nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. This version of the Toto® Drake® includes CEFIONTECT®, a layer of exceptionally smooth glaze that minimizes waste from sticking to the ceramic. CEFIONTECT®, coupled with PREMIST and TORNADO® flush, assists to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals and time required for cleaning.
