General Questions

Is the seat comfortable for taller or broader users?

Both models are designed with a wider, more supportive seat profile for improved everyday comfort. The enlarged seating area helps create a more relaxed experience for a broader range of body types.

Is the washing water fresh and comfortable?

Yes. The cleansing system is designed around fresh running water and filtered delivery for a cleaner, more comfortable experience. Instant heating also helps provide steady warm water during use rather than relying on stored water.

Will it work in homes with lower water pressure?

The system is designed to support stable performance in a wider range of home conditions. For households concerned about water pressure, the built-in tank and booster-supported design help improve usability where conventional setups may feel more limited.

Is a smart toilet difficult to use every day?

Not at all. Both models are designed for simple daily use, with clearly labeled controls and easy-to-understand functions. Once set up, most features feel intuitive and comfortable, even for first-time users.

What is the difference between U5 Essential and U5 Ultra?


Both models are designed to deliver a premium smart toilet experience, but the U5 Ultra includes a more advanced feature set for users who want added convenience, personalization, and upgraded hygiene-focused functions. The U5 Essential keeps the core daily-use experience clear, comfortable, and easy to enjoy, while the Ultra adds selected premium enhancements such as automatic lid operation, UV sanitation, infrared comfort care, a 360° foam shield, and 256-color ambient lighting.
