This is the Charmkit Litter Box: a smart litter box with an automatic door system, video monitoring and smart ventilation. It uses negative ions for deodorization to keep your home smelling fresh. It has 68L capacity.
This litter box has an infrared beam system for safe operation. The machine doesn’t run as long as your cat is around. The drum has a camera that lets you monitor your cat in real-time. You can find this project on Indiegogo.
