No, the Litter-Robot does not require special bags or liners for the waste drawer. As long as it fits, you can use it. Customers often use 35 to 50-litre kitchen garbage bags or large plastic grocery bags. If you’re looking for an eco-friendly option, check out our custom-fit, biodegradable Waste Drawer Liners in various size packs (three come free with each Litter-Robot).
