Living with it
What the maker’s own pages and manual say about owning this unit, and what owners report in public. Each line links to where it was read.
- Consumables
- Neakasa's own FAQ says owners are not locked into proprietary trash bags: any bag that fits the waste drawer can be used, even though Neakasa also sells replacement bag rolls.neakasa.com
- Without the app or Wi-Fi
- If the Wi-Fi connection drops, the M1 keeps cleaning on its last settings, but per-cat activity stops being logged in the app until the network reconnects.neakasa.com
- Set-up
- On first fill, Neakasa tells owners to add roughly 5-6 kg of litter and keep it within the printed scale range on the chamber rather than guessing a level by eye.neakasa.com
- Maintenance
- Neakasa's own FAQ says the waste bin only needs emptying about every 14 days for a single cat, and owners can check its status remotely in the app instead of opening the unit to look.neakasa.com
- Warranty
- The manual itself still prints a 12-month warranty, but Neakasa's current warranty-policy page extends coverage to 2 years for M1 Plus units purchased on or after January 1, 2026.neakasa.com
- Support and parts
- Neakasa's FAQ points owners to a dedicated M1 FAQ page first and, failing that, a support email and a US toll-free phone line staffed on weekday business hours.neakasa.com
- Known issue
- Kittens under 2.2 lb are not supported in automatic mode at all -- Neakasa's FAQ says owners of kittens that light must switch to Kitten Mode with automatic cleaning turned off.neakasa.com
- Safety
- Neakasa's FAQ describes the pause mechanism in more operational detail than the marketing spec sheet: the weight sensors hold the machine still for the entire time a cat is inside, not just at the moment of entry.neakasa.com
What owners and long-term reviewers report, from public threads and published reviews; not our own testing.
- Cats can take very different amounts of time to adopt the M1 -- one owner's two senior cats included one that used it immediately and one that took several days to start using it daily.cats.com
- At least one owner with a single cat found the waste bin filled up in under a week, though still preferred it to manual scooping.cats.com
- A recurring owner complaint is urine leaking through a small gap in the interior mat's seam, which Neakasa tries to address by including silicone sealing stickers.cats.com
- The waste bin can falsely flag itself as 'full' when clumps pile up unevenly in one spot, which shuts the machine down and blocks cats from using it until it's cleared.cats.com
- The M1's gray plastic surface shows dust quickly, so owners should keep wipes on hand for regular upkeep.cats.com
- At least one cat refused to use the M1 at all despite the owner's efforts, appearing to be in pain near it, and the owner reverted to the old litter box.cats.com
What independent testers found
We do not test units ourselves. These are figures and verdicts published by named testers, with the maker’s claim beside them where the tester gave it; where a tester relays owners’ reports rather than a measurement, the row says so.
- Cats.com's hands-on review scored the Neakasa M1 an overall 4/5, calling out its open-top design as a genuine differentiator while flagging construction and appearance as the weakest categories. (4/5 overall (Ease of Cleaning 5/5, Odor Control 4/5, Appearance 3.5/5, Construction 3.5/5, Price 4/5)) Cats.com (Liz Coleman)
