Litter-Robot 4

Key facts

• Self-cleaning globe rotation handles multiple cats on one waste drawer
• No subscription — the app and all cycling features are free
• Takes any clumping litter; liners and filters are optional, not proprietary
• Cycles on its own schedule even with Wi-Fi down

Our verdict

The Litter-Robot 4 stickers at $699, but the receipt above is the real price: $1,131 over three years, or about $12 a month in running costs after the box arrives. There is no subscription, and there never has been — what you pay at checkout plus consumables is the whole story.

Consumables run about $12/mo (any clumping litter + optional liners/filters) and are not proprietary, so you can shop around. The core function keeps working if the app, cloud, or your Wi-Fi goes down — a reliability point we weight heavily.
