The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Neakasa M1 Plus is the automatic box most often recommended for larger and stockier cats, thanks to its open-top design. Community comments are notably consistent on this point: one r/litterrobot owner with a 'solid, stocky gray cat' said he 'jumped in almost right away,' and r/CatAdvice users praise it as 'so much more spacious and comfortable' and easier to deep clean than rivals. A Facebook group summary in the signals notes most owners praise the open-top design and ease of cleaning.
What reviewers liked
- Open-top design repeatedly praised for large and stocky cats across communities
- Reviewers find it easier to deep clean and quieter than some rivals
- Manufacturer now ships extra seals to address early leak complaints
Where it falls short
- Lowest automatic rating in the pool at 4.0 across roughly 4,351 reviews
- Community threads cite wifi connectivity and occasional mechanical issues
- cgmagonline notes it disposes of relatively little litter per cleaning cycle

The counterweight is real and keeps the score in check. Its Amazon average is just 4.0 across roughly 4,351 reviews, the lowest of the automatics here, and the same community threads cite wifi connectivity glitches, occasional mechanical problems, and early leak issues that Neakasa now addresses by shipping extra rubber seals. cgmagonline observes it 'does not dispose of much litter when it cleans itself,' a functional limitation rather than a defect.
For owners with big cats who want an automatic box, the open-top form factor is the genuine draw; the trade-off is the lower aggregate rating and the connectivity and sealing quirks reviewers repeatedly flag.
- 【Enhanced Safety Detection】Upgraded from 5 direct infrared sensors to a 6-array rotary infrared system. Multi-angle scanning improves detection accuracy and reduces false triggers by continuously tracking a cat’s position, helping support safer everyday use, especially when curious cats approach the unit.
- 【Odor & Anti-Leak Sealing】A built-in brush strip creates a tight seal to help block odor escape during use. The upgraded composite sealing ring adds an extra barrier to reduce liquid seepage and minimize floor mess, cuts leakage to <5% with no sticker needed anymore.
- 【Pioneering Open-Top Design】Open-top design aligns with cats’ natural instincts, offering a more open, visible space that helps cats feel safer and more in control, especially ideal for large breeds transitioning from traditional litter boxes.
- 【Multi-Cat & Kitten Friendly】Supports 3.3–33 lbs and up to 3 cats, with a dedicated Kitten Manual Mode for <3.3 lbs.
- 【7–14 Days Low-Maintenance】11.2L large waste bin and 7.2L litter capacity support up to 7–14 days of use, ideal for busy weeks or short trips. The Pull & Wrap system seals waste in seconds, no touching, no mess, no odor.
- 【Smart App Control】Use the Neakasa App (supports 2.4GHz Wi-Fi only) to track daily litter box activity and adjust modes remotely. Monitor your cat’s litter habits over time to better understand bathroom patterns and notice changes.
- 【Box Contains】Comes with Main Unit ×1, Support Legs ×4, Litter Mat x1, Refill Bag Rolls ×2, User Manual ×1, Quick Start Guide ×1
- 【2-Year Protection】The Neakasa M1 Plus self-cleaning cat litter box is backed by an extended 2-year protection plan for added peace of mind.
The reviews were quite different from each other, but overall mostly positive. Some reviews say automatic litter boxes are bad because you can't ...
I have the Neakasa M1 and love it. They now send out extra little rubber seals to add around the main rubber dam on the bottom to keep any urine ...
