The TOTO S7A is equipped with a motion sensor that detects your approach and automatically opens the toilet seat or lid, based on your preferences.
After use, the system intelligently waits for a brief period of inactivity (about a minute) before closing on its own.
The sensitivity of the motion sensor can be adjusted if the user finds the seat to be too reactive. A timer can also be turned on so that the seat won't open for at least a minute in case someone just walks by the toilet.
Not ever having to touch a dirty toilet lid increases hygiene and stops the spread of germs. This feature is particularly beneficial for those with mobility challenges, such as post-surgery recovery, simplifying their bathroom routine.
It's also just really cool.
