Bought when pregnant with 3rd child. My husband travels a lot with work and my 4 and 6 yr old was not a good choice to do the litter box. Two years later, we still love it and no problems.
We have the cat genie located in the unfinished part of the basement. We were able to add into the water line and drain it right into the septic line. It does not drain in the bathroom or laundry space.
The cat uses it with no issues and there is no smell. Very happy with the cat genie!
