I am disappointed in this litter box.  The idea is great, unfortunately it does not empty the poo well and collects the poo behind the rake and it gets all over the machine.  I will not be using this as a litter box.   I am going to return it.  I understand that Way Fair is a distribution company and not responsible for the quality of the litter box.  I  dont know how their response will be on returning a costly litter box so I cant rate that yet.
