At present, the pain point of automatic cat litter boxes on the market is that the smell of cat feces cannot be solved. After the litter box was cleaned, it fell into the storage box, but the taste was still there, and it was still emitting a bad smell. Therefore, the design of this model is that the garbage bags in the storage box have the function of automatic packaging. Through the pressure sensor, the cat's excrement will be automatically packed after reaching a certain weight, thus blocking the emission of odor.
