Summary
WIRED's current top pick thanks to a built-in 1080p AI camera with 210-degree view, multi-cat face recognition, and a self-sealing waste bag that holds up to 17 days of waste. The 43% larger opening vs. its predecessor makes it viable for big cats.
The buy-it-for-life solution to litter odor — stainless steel doesn't absorb ammonia like plastic does, cleans in seconds, and lasts decades. Reddit's r/BuyItForLife community overwhelmingly recommends it over any plastic alternative.
Pros
- Built-in 1080p camera with night vision, 210-degree view, and AI multi-cat face recognition
- Self-sealing waste bag stores up to 17 days of waste for one cat
- 43% larger opening than previous model — works for cats up to 22 lbs
- Dual odor eliminator cartridges plus sealed waste bin for near-zero smell
- Works on both 2.4GHz and 5GHz Wi-Fi networks
- Does not absorb urine odor like plastic — stays genuinely odor-free after cleaning
- Lasts years to decades vs. plastic boxes that need replacing every 6 months
- Easy to fully sanitize with soap and water — no hidden ammonia buildup
- High-walled XL options available on Amazon for $40-$120
- Works with any litter type including wood pellets and tofu litter
Cons
- App is overcrowded with ads for other Petkit products
- Multi-cat face recognition degrades significantly after free Care+ subscription ends
- Camera is not movable or repositionable
- Proprietary waste bags and refill rings required ($35 for 3)
- Requires manual scooping — no automation
- Some XL options can be too narrow for very large or wide cats
- Higher upfront cost than cheap plastic boxes (though far cheaper than auto-boxes)
- Stainless is not fully stain-proof — can still discolor over time
Our take
If you want the most tech-forward litter disposal system on the market right now, this beats the Litter-Robot 4 on features — the camera and health monitoring are genuinely useful, not just gimmicks.
If you don't want to spend $500+ on a robot, this is the smartest upgrade you can make. Plastic litter boxes are the hidden source of most litter odor — switching to stainless eliminates that permanently.
