Yes. However, SmartScale™ technology to record cat weight is most accurate on a firm surface, not carpeting. If you plan to use Litter-Robot 4 on carpet that’s 3mm+ thick or on uneven flooring, you can improve the accuracy of SmartScale™ weight readings by purchasing our specially designed Carpet Tray that sits between the unit and the floor. The carpet tray is not required for Litter-Robot 4 to function.

As clumps start to collect in the drawer, the readings will become more accurate. For the most precise waste drawer readings and a seamless experience, we highly recommend using Litter-Robot Waste Drawer Liners.
