The Petloo smart cat toilet is equipped with advanced smart sensor system, which can automatically sense the whole process of the cat in the toilet and choose the machine to clean. Petloos safety interrupt system is triggered when a cat gets close enough to enter the machine at any moment of operation. The built-in 250nm ultra-short wave ultraviolet UVC disinfection light will regularly disinfect the cat feces stored in the feces collection box to ensure that the short-term stored feces will not pollute the living environment of people and pets.
