TOTO ST454EA Technologies and Benefits:
Tornado Flush™: The Tornado Flush™ features two powerful nozzles that create a centrifugal, cyclonic rinsing action which reduces waste buildup and keeps the bowl cleaner. Using only 1.28 gallons per flush, this high-efficiency system is more effective in one flush than most toilets are with multiple flushes. The modern hole-free rim design means that it performs more consistently and is easy to clean.
