Buying Guide: What to Look for in an Extra Large Automatic Litter Box

Capacity and Size

The whole point of an extra large litter box is to accommodate multiple cats or large breeds without frequent emptying. Look for a drum capacity of at least 80 liters and a waste bin that can hold a week or more of waste. For example, the Cumrige model offers a 95L drum and a 15L waste bin, while the Happypaw XXXL provides a 12L waste capacity that can last up to 20 days. Ensure the entrance is wide enough for your cat to enter comfortably. For more on choosing the right size, see our motorized dog door reviews for insights on pet access.

The Mimfam model features a spacious top entrance measuring 16.33 x 15.35 inches, making it easy for large cats to enter. The Fumoi and Ellenpent models also offer large drums of 86L and 90L respectively. Consider the layout of your home and the number of cats to determine the ideal capacity for your needs.

Safety Features

Automatic litter boxes involve moving parts, so safety is paramount. Look for models with infrared sensors and weight sensors that pause the cleaning cycle when your cat approaches. The Mimfam model uses four pairs of infrared sensors and three hall sensors for comprehensive detection. The Happypaw includes an anti-pinch design and advanced infrared sensors that immediately halt operation.

Additionally, some models like the Cumrige and Fumoi use advanced sensor systems to ensure your cat is never disturbed. Always choose a product that prioritizes your cat’s well-being. For more on smart pet care, read our smart pet care system reviews for 2026 for additional insights.

Smart Features and App Control

Many modern automatic litter boxes offer Wi-Fi connectivity and dedicated apps for remote control. You can monitor cleaning cycles, receive waste bin reminders, and even track your cat’s bathroom habits. The Cumrige and Fumoi models both work with the Tuya Smart app, while the Happypaw provides health alerts. These features add convenience and help you stay on top of your pet’s health.

Odor Control

A sealed waste bin and odor-absorbing materials are essential for keeping your home fresh. The Happypaw uses a triple-lock system with a non-stick tray, active odor eliminator, and silicone gasket. The Ellenpent model features double defense with ABS material and scented gel.

Many models also offer disposable liners and deodorizing packs to further reduce smells. The Mimfam includes liner bags and a cat litter mat for easy maintenance. Evaluate the odor control features to ensure a pleasant living environment.
