21 gal (78 L) Self-Cleaning Cat Litter Box with App Control

This enclosed, egg-shaped litter box cleans itself so you scoop less. A 78 liter chamber gives a large cat, or several cats, room to move, and the closed shell helps contain odor and keep litter from scattering across the floor. You can start a clean from your phone through the app, and the app also tracks bathroom visits, so you can notice changes in your cat's habits.

Safety sensing is built in. A 120 degree radar, weight detection and an anti-pinch design are designed to pause the cycle when a cat approaches or is inside. The motor is described as quiet, which helps with skittish cats and light sleepers. Every key part detaches without tools, and an anti-stick litter pad makes wiping the base easier.

The box is about 19.7 inches wide, 19.7 inches deep and 20.9 inches tall (50 x 50 x 53 cm) and weighs 19.85 lb (9 kg), so it needs a spot with floor space and an outlet nearby. Introduce your cat gradually, keeping the box switched off at first, and empty the waste drawer regularly. Check the sensors are clear of litter dust, and keep an eye on how your cat uses it for the first few days.
