UV Sterilization litter trays?

[Breadcat24]

Dear Posters of the Litter Tray I need your help please
We are looking to get a new rescue cat and will of course be keeping he in for a while.
The late and much loved Breadcat could kick cat litter for Britain! So I have been looking at enclosed litter trays. Some say they have UV sterilization to reduce odour. Does anyone have one? Do they work?
Of course we will clean daily anyway
What are your thoughts?

I just have a normal hooded tray. I don’t know why it would need to be sterile for them to poo in!

@Toddlerteaplease I think it is supposed to kill bacteria after but it may be a gimmick. Either way I would not want it lighting up when the cat was in it!
