Waste Drawer Capacity6.5L sealed bin (~7 days for multi-cat use)

The Cosmillio Open Top Automatic Litter Box is an infrared-sensor-driven self-cleaning box with a rake mechanism designed for large cats. It features a 5.8L capacity, a 6.5L sealed waste bin (supports ~7 days of hands-free use), and a "Pull & Wrap" disposal system for touch-free odor control. The unit connects via smart app for remote monitoring, usage tracking, and multi-cat household data.

Litter compatibility: Works with bentonite, mineral, cassava, and crushed tofu litter—avoid crystal and pure tofu varieties.

Key specs: Open-top design (28.5L × 18.35W × 10.12H inches), non-stick Teflon liner, 4 infrared safety sensors, WiFi-enabled app control. At $159, it's positioned as a mid-range option for busy households and multi-cat environments, though brand awareness and long-term reliability data remain limited in English-language cat communities. Initial feedback suggests decent performance, but owner reviews and defect rates lag behind category leaders like Litter-Robot and PETKIT.
