3. Premist Function

• Before each use, the Premist function automatically sprays a fine mist of water onto the toilet bowl surface. This creates a hydrophilic layer that makes it difficult for dirt to stick and easier to wash away.

4. Auto Open/Close Lid

• The toilet lid automatically opens when a user approaches and closes when they leave, providing a hands-free and hygienic experience. This also contributes to energy saving by preventing the lid from being left open.
