The washlet® dual flush elongated two-piece toilet (seat included) with premise combines the comfort and convenience of Toto's bidet seats with the power of Toto's 3d tornado flush system. The washlet g400 comfort features begin as you approach the toilet. The lid automatically opens hands-free to welcome you. The automatic premise sprays the CEFIONTECT toilet bowl surface. CEFIONTECT, toto®’s innovative ceramic glazing, prevents waste from sticking to the bowl. The combination of the premise and CEFIONTECT helps to minimize the frequency of cleaning, reducing the amount of water, harsh chemicals, and time required to clean the toilet. When you take your rightful place on the toilet, you can feel the warmth of the heated seat. The seat has 5 seat-warming temperature settings that are especially useful during the cold of winter. An automatic air deodorizer activates to hide unpleasantries. As your journey comes to a close, you can access the remote control and start the cleansing process. A self-cleaning wand will appear to wash your nether regions. You are in total control, as you select a front to cleanse, soft rear cleanses, rear cleanse, oscillating cleanse, or pulsating cleanse. The variable temperature and pressure settings allow you to adjust the warmth and intensity of the spray. You may also decide to save your preferences with the two-user memory feature so that you may instantly access those at a later visit. You may start the air dryer with 5 temperature options to reduce the moisture left behind from the cleaning. The automatic dual-max flush will determine the necessary flush volume and begin as soon as you rise. The powerful flushing of the 3d tornado flush, aided by the CEFIONTECT glaze whisks away all of the evidence. Upon leaving, the lid automatically closes as if saying “goodbye.” using a washlet® reduces the need for toilet paper, saving trees and water used to manufacture each roll. As we get older, our mobility can deteriorate and make it increasingly hard to clean ourselves after toileting.
