It costs more or less $350 if you can still find refurbished units.

Final Remarks
The Litter Robot series is an incredible innovation for cat owners. All models employ the same self-cleaning mechanism which is very reliable and efficient, giving you more than a couple of worry and hassle-free days.

The sensors installed in all models isn’t exactly enough to detect kittens weighing less than 5lbs, so you have to manually initiate the robot’s self-cleaning routine. Aside from that, all features are excellent and effective in doing the job of containing your cat’s litters.

If you have a cat at home and you’re often away for work or out of town trips, this automatic self-cleaning robot is a good investment to your household. You won’t need to worry anymore about litters scattered around the house, giving your more time to play with your cats instead of cleaning their mess.
