It depends on how many cats use the Litter-Robot, how big they are, and your personal preference. On average, for one adult cat, it is typical to empty the waste drawer once every 7-10 days; for two adult cats, you may need to empty the waste drawer up to two times per week. Check out this infographic for more information.

The Litter-Robot Open Air is equipped with infrared emitters and sensors that detect the level of waste in the drawer. A light on the control panel will come on to alert you when the waste drawer is full and needs to be emptied.
