I have been wanting one of these machines for a long time, I was skeptical at first about how well it would work, but this thing is amazing and effective in removing solids. It took my cat a little bit to get used to it but is now using only this litter box. My son used to complain about cleaning the cat box and now with the app he gets a notification when it needs to be emptied and it’s as easy as tying the bag and throwing another bag in. It comes with a scent pod so it keeps the odor under control and you can use regular clumping litter which is nice not having to buy a separate tray every time or a specific litter. This is definitely a game changer if your looking to not scoop liter anymore.
