A device for automatically providing a disposable seating-surface cover for a toilet-seat, comprising: a) a first housing adapted to feed a disposable seating-surface cover roll installed therein, wherein said cover roll is a long strip layer that comprises plurality of similar apertures and a control indication located adjacent to each aperture , so that each aperture defines an individual seating-surface cover ; b) a second housing adapted to receive and collect the roll by connecting an initial edge of said roll to a rotational mechanism situated in said second housing and equipped with a motor , said rotational mechanism is adapted to pull said roll such that each individual disposable seating-surface cover follows a preset displacing movement where one individual disposable seating-surface cover is positioned in a state of use, wherein when an individual seating-surface cover of the roll is in a state of use, it lies directly on a seating surface of a toilet-seat, such that the aperture of the individual seating-surface cover is parallel to an aperture of said toilet-seat, wherein said first and second housings are physically connected by supporting rails or arms ; c) an optical reader located at said first housing and/or said second housing , wherein said optical reader is configured to capture visual information of said control indication and to translate the captured visual information into digital information that reflects a triggering signal that indicates when to stop the feeding process of said cover through the stopping of the motor, as to enable the preset displacing movement; d) a bracket arrangement adapted to install said device to said toilet-seat in a way that allows said device to pivot away from said toilet-seat when said device is not in use; and e) a lifting arm for enabling a hands-free lifting/lowering of a toilet-seat flap of the toilet-seat. a) a first housing adapted to feed a disposable seating-surface cover roll installed therein, wherein said cover roll is a long strip layer that comprises plurality of similar apertures and a control indication located adjacent to each aperture , so that each aperture defines an individual seating-surface cover ; b) a second housing adapted to receive and collect the roll by connecting an initial edge of said roll to a rotational mechanism situated in said second housing and equipped with a motor , said rotational mechanism is adapted to pull said roll such that each individual disposable seating-surface cover follows a preset displacing movement where one individual disposable seating-surface cover is positioned in a state of use, wherein when an individual seating-surface cover of the roll is in a state of use, it lies directly on a seating surface of a toilet-seat, such that the aperture of the individual seating-surface cover is parallel to an aperture of said toilet-seat, wherein said first and second housings are physically connected by supporting rails or arms ; c) an optical reader located at said first housing and/or said second housing , wherein said optical reader is configured to capture visual information of said control indication and to translate the captured visual information into digital information that reflects a triggering signal that indicates when to stop the feeding process of said cover through the stopping of the motor, as to enable the preset displacing movement; d) a bracket arrangement adapted to install said device to said toilet-seat in a way that allows said device to pivot away from said toilet-seat when said device is not in use; and e) a lifting arm for enabling a hands-free lifting/lowering of a toilet-seat flap of the toilet-seat. <EOS>
