Used for about one month and forgot to return (I just don’t have enough time) so my loss your gain, we can do a run at my house if you’d like to show it’s working. It’s great just not for my house. Comes with scented full new, 4 new maintenance packs, extra parts that came with it, extra tubing, and the T needed for attachment. All you need is litter, (no low ballers this $ goes to a baby crib)
