5. Operating Instructions
Your LALAHOO Smart Tankless Toilet offers several convenient features for enhanced comfort and hygiene.
5.1 Automatic Flushing
- Seat Sensor: The toilet is equipped with a seat sensor. After 10 seconds of being seated, the toilet will automatically flush once the user stands up and moves away.
- Foot Sensor: For hands-free operation, a foot sensor is located at the bottom right of the toilet. Simply swipe your foot near this sensor to activate a flush. This feature is particularly useful for men's urinal flushing, eliminating the need to bend down.
