<p>The lavatory seat automatically sucks out any odours from the lavatory bowl when it is used. The seat is hollow and has openings inside it, opposite each other on either side. The odours are sucked out through these and are channelled into the seat and are then compressed by a tube which has a mini-suction pump. The odours are evacuated through an external outlet or into an aeration tube. Under the seat there is a switch which automatically operates the pump when the seat is sat upon.</p> |
