Summary
The most practical automatic litter disposal system for most cat owners — cheaper than flagship models, triple odor control, and a rotating design that makes refilling litter dramatically easier. Compact enough for apartments.
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.
Pros
- Box rotates so the hole faces up for easy litter refilling — unique among competitors
- Triple odor control: sealed waste bin + odor-eliminator attachment + citrusy deodorizing spray
- Displays cat weight on front panel at every visit
- App logs every use, cleaning cycle start/end, and deodorizing spray events
- More compact footprint than Litter-Robot 4
- 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
Cons
- No automatic sensor for low litter levels — must check manually or set reminders
- App is cluttered with ads for other Petkit products
- Cheaper than flagship models but still $370-$500
- 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)
Our take
This is the sweet spot for people who want automatic litter disposal without paying Litter-Robot prices. The triple odor system is legitimately impressive — reviewers say it smells good, not just neutral.
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.
