The TOTO® Soiree™ Toilet features the Double Cyclone™ flushing system. Using two powerful nozzles, the Double Cyclone™ flushing system creates a forceful centrifugal action that cleans the rim and bowl thoroughly with every flush. The rim has no holes, which makes it easier to clean and offers a seamless appearance. SanaGloss™ glaze seals the surface, creating a finish that actually repels stains caused by buildup of mineral deposits.
