In the event that Cleana Toilet Seat’s mechanism stops working, first, examine the seat’s hinge to identify whether an excessive build-up or dirty or a foreign object is obstructing its movement. If the hinge area is clear and the seat is still unable to reset, there is likely an issue with its internal components. Please contact us through our phone or email to describe the malfunction if this occurs, and we will provide you with a complimentary replacement unit. Luckily though, Cleana Toilet Seat functions perfectly fine as a standard toilet seat when broken, meaning no downtime for your restroom!
