This Aimes Rest room employs Twister Flush Technology, which siphons drinking water with two strong nozzles, harnessing the power of water and gravity to maximize cleansing and use drinking water far more proficiently. CEFIONTECT® ceramic glaze results in an extraordinarily sleek area that helps continue to keep the bowl cleaner longer. http://www.zybls.com/home.php?mod=space&uid=563417
