Key Features & Innovations

Tornado Flush Technology

The Tornado Flush features two powerful nozzles that create a centrifugal, cyclonic rinsing action which reduces waste buildup and keeps the bowl cleaner. Using 1 gallon or 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.

  • Dual-nozzle water propulsion system
  • More powerful flush
  • 1 gallon or 1.28 gallon per flush
  • Cleaner bowl and less cleaning

TOTO's extraordinarily smooth CeFiONtect glaze prevents particulates from adhering to porous, ceramic surfaces. The ion-barrier in CeFiONtect keeps everything cleaner, longer. Less cleaning means fewer chemicals in the environment and less water used for cleaning.

The surface layer that makes up the ionized barrier is more consistent and uniform and has a higher density on the CeFiONtect surface than on the conventional surface.

Creating more smoothness helps minimize debris from sticking. With nothing to cling to particles can be washed away with every flash.

Electrolyzed water is a proven disinfectant used in food preparation and cleaning. Using the incoming water supply, a pre-mist wets the toilet bowl surface aiding in the elimination of waste approximately 80% better than a dry bowl. After each flush, TOTO’s eWater+ mists the bowl with electrolyzed water, reducing the need for harsh cleaning chemicals.
