Litter-Robot 4: Waste drawer liner installation guide

Emptying Litter-Robot is easy as taking out the trash with custom-fit waste drawer liners, made specifically for Litter-Robot.

Litter-Robot does not require special bags or liners for the waste drawer, but clear bags work best. Customers often use 10- to 13-gallon clear kitchen garbage bags or large clear plastic grocery bags. Please note that waste level readings may be inaccurate when using a dark bag, especially when the drawer is empty. As clumps start to collect in the drawer, the readings will become more accurate.

Empty the waste drawer when indicated by the app or the flashing blue light on the control panel. How often you empty the waste drawer depends on the number and size of your cats. For two average-sized cats, twice per week is typical. For a single cat, once per week is usually sufficient.
