The new drake toilet features toto™s Dynamax Tornado Flush®, utilizing a 360-degree cleaning power to reach every part of the bowl. The Dynamax Tornado Flush system has a hole-free rim design with dual nozzles that creates a centrifugal washing action that assists in rinsing the bowl more efficiently. The enhanced design of the drake inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. The left-hand chrome trip lever allows you to proactively conserve water by choosing between a 0.8 GPF rinse or 1.6 GPF for tougher jobs. This version of the drake includes Cefiontect, a layer of exceptionally smooth glaze that prevents particles from adhering to the ceramic. Cefiontect, Ewater+®, and tornado flush create a synergy that optimizes flush performance to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The hidden connection on washlet+ models provides a streamlined look and gives the impression of an integrated system and the universal height design allows for a more comfortable seat position across a wide range of users.
