PetSafe self cleaning automatic litter box

I have a used but perfectly clean/sanitized Pet Safe litter box. It’s in perfect working order. Please see photos for details. I also have 6 brand new replacement trays plus crystal litter. These alone are worth over €100. The litter box is fitted with a plastic reusable tray so you can use whichever you prefer. You only need to buy litter once the 6 you have run out. This has been invaluable in our house and we are only selling as we have upgraded to a rotating drum.
