i-wave Cleaning Technology
Proprietary technology that uses a thorough four-step wash and rinse process, providing the perfect combination of water pressure, air and time. Every time.
Find the clean that best fits your body. Adjust water temperature, water pressure, seat temperature and more. All with a tap.


Bidets are better for everyone. So we specifically designed every bidet to work for every body.
• Children
• Elderly
• Overweight
• Visually impaired
Bidets can have profound health benefits for women. So we created a female-specific cleaning mode designed exclusively for:
• Urinary tract and bladder infections
• Menstruation
• Pregnancy
• Inflammatory bowel disease


The built-in warm air dryer eliminates the need for toilet papers.
Stay goodbye to a cold seat forever with fully-customizable seat temperature settings.


The self-cleaning care system keeps the inside and outside of the bidet hygienic. Giving you better health and peace of mind.
With the nozzle made from stainless steel, you can wipe off dust easily and always use the product hygienically. Also, the separate cleaning nozzle and bidet nozzle keep the product more hygienic.


IPX5 technology is built to withstand a sustained, low pressure spray, making it easier to keep it safe and sanitary.
The built-in Eco system switches the bidet toilet to the standby mode when not in use to save the electric power and lower the electric consumption.



Whether researching over 100 million data points to document air quality, conducting hundreds of tests to create the perfect seat for every body shape or employing twenty-six certified water sommeliers, when we say we’re obsessed with health, we mean it.
