Operation Theory: The Hygiene Toilet Seat Covers will automatically replace the used film roll to a new film cover, which can provide a new toilet seat for your every usage. This happens when the user put hand in front of the sensor device or when the stainless steal button is pressed by the user.
Just by pressing the stainless steel button or putting your hand before sensor device before your usage, the roller will activate automatically to replace the used seat film with fresh one to ensure a new toilet seat for your every usage, which is much easy & convenient.
