This wall-hung toilet is stylish, silent, sanitary and energy-efficient. It adopts a one-piece design featuring a flat lid and uses 30% less water than traditional toilets. The seat is made from antibacterial material, while the self-cleaning nozzle automatically performs thorough cleaning with fresh water before and after each use to prevent infection and ensure safety. The automatic opening and closing of the lid by microwave sensor, as well as the three cleaning modes, SPA cleansing, smart deodorization, and high-speed tornado flush ensure fast, clean and safe operation.
