What Is the Neakasa M1 Plus?
The Neakasa M1 Plus is an automatic, self-cleaning litter box built to serve multiple cats from one unit — the listing puts the supported weight range at 3.3 to 33 lbs and up to three cats sharing the box, with a separate Kitten Manual Mode for cats under the minimum weight (automatic sensing on very light cats is a common false-trigger risk across this whole product category, which is why brands gate it behind a manual mode). It ships with the main unit, support legs, a litter mat, two refill bag rolls, a user manual, and a quick start guide, and Neakasa backs it with a 2-year protection plan — longer than the 1-year coverage that's typical on budget automatic litter boxes.
How We Picked This
This isn't a hands-on test writeup. We picked the M1 Plus by checking it against our own Pets buying guide's framing — automation in pet care is an everyday-convenience upgrade over a manual routine, not a substitute for supervision, and it's worth the higher upfront cost mainly for households that will actually use the automation daily rather than occasionally. We weighed the M1 Plus's multi-cat capacity and 2-year protection plan against Amazon's aggregate verified-purchase rating (4.0 out of 5 across roughly 3,400 ratings). This is disclosed research, not the multi-week in-use testing we run when it's practical — see how we test products.
Key Features
Three things matter most when deciding if an automatic litter box like this fits a multi-cat household.
Multi-Cat, Multi-Weight Support
Supporting up to three cats and a 3.3-33 lb weight range in one unit means a household doesn't need a separate box per cat — a real space and cost saving, though sharing one box across multiple cats can still trigger territorial guarding behavior that no hardware design fixes on its own.
Kitten Manual Mode
Cats under the 3.3 lb minimum use a manual mode instead of the automatic sensing cycle — a sensible safety gate, since automatic cleaning cycles triggering on a very light or young cat is a known risk across this whole category, not specific to this unit.
2-Year Protection Plan
Longer coverage than the 1-year warranty typical of budget automatic litter boxes, though what exactly it covers (parts, labor, or both) is worth confirming on the current listing before treating it as equivalent to a full manufacturer warranty.
What Amazon Buyers Say
As of writing, the M1 Plus holds a 4.0-out-of-5 average across roughly 3,400 Amazon ratings. We didn't generate this number ourselves; it's Amazon's own aggregate verified-purchase data, visible on the product listing linked below. A 4.0 average with a large sample size is solid but not exceptional for this category — worth reading a spread of recent reviews (not just the top-voted ones) for any recurring complaints about the cleaning cycle or odor control before buying.
Where to Buy the Neakasa M1 Plus

Who Should Buy the Neakasa M1 Plus?
Households with one to three cats who want to cut daily scooping down to occasional maintenance, and who are comfortable with the higher upfront cost of automation. It fits the "everyday-convenience upgrade" category from our Pets buying guide — worth it if the automation will genuinely get used every day.
The Neakasa M1 Plus is NOT right for you if: you have cats that don't get along and are likely to guard a shared box from each other — automation doesn't solve a multi-cat territorial problem, and you may be better off with two smaller boxes instead of one large automated one.
Other Pets Picks
If an automatic litter box isn't what you're shopping for, here's what else we're currently featuring in the same category — not direct substitutes, just other researched picks:
- PETKIT Purobot Max Pro 2 — pricier AI-camera automatic litter box with per-cat facial recognition and urine pH tracking, if health monitoring matters more than price
- FurEase — grooming tools, automatic feeders, carriers, and beds
- Canivet — at-home dog dental care tools
Final Verdict: Is the Neakasa M1 Plus Worth It?
For a one-to-three-cat household ready to pay more for daily convenience, the M1 Plus's multi-cat capacity and above-average 2-year protection plan are a fair trade against its higher price and the reality that automation can't resolve territorial conflict between cats sharing one box — a solid pick if your household fits that profile, per our buying guide's own logic on pet-care automation.
