The TOTO USA Neorest 700H and 550H use dual-flush, high-efficiency flushing and eWater+ technology. The Cyclone flushing system creates a whirlpool effect that removes waste and cleans the bowl’s surface and rim. After each flush, eWater+ mists the SanaGloss-glazed bowl with electrolyzed water, which has a slightly acidic pH value, preventing waste’s adherence 80% better than dry porcelain. The toilets use 1-gpf for the full flush and 0.8 gpf for the light. These toilets can be installed in high-rise, multifamily buildings and the upper floors of single-family residences.
