Description
Open-top self-cleaning boxes usually work best when they solve the biggest adoption problem first: cats need space to see where they are stepping. The Neakasa M1 Plus keeps that more natural open approach while adding stronger odor control, safer motion detection, and a more polished daily waste routine than many lower-cost enclosed boxes.
SmartPaw selected the M1 Plus because it gives shoppers a stronger premium option inside the current litter lineup. It adds a better fit for large breeds, clearer multi-cat positioning, and a cleaner pull-and-wrap disposal workflow that feels easier to live with during busy weeks or short trips.
Product highlights

- Open-top entry feels more natural for larger cats, cautious cats, and households transitioning from standard litter pans.

- 11.2L waste-bin capacity and 7.2L litter volume support roughly 7-14 days of lower-touch maintenance for many homes.
- Pull-and-wrap waste handling plus upgraded odor and anti-leak sealing helps keep cleanup faster, cleaner, and more contained.

Best for
- Large cats or cats that avoid tight enclosed automatic litter boxes.
- Multi-cat homes that want longer stretches between waste-bag changes and less manual scooping.
- Pet parents shopping for a more premium open-top litter box with stronger safety messaging and habit tracking.
Placement and setup blueprint

- Leave enough side clearance around the open top so larger cats can approach without feeling boxed in or crowded.
- Keep the unit on hard, level flooring or a stable litter mat so waste separation and detection stay more consistent over time.
- Avoid corners that trap odor or high-traffic pathways where cats may feel interrupted while entering the box.
Pre-flight checklist
- Confirm the waste bag is seated cleanly in the pull-and-wrap track before the first automated cleaning cycle.
- Pair the 2.4GHz app connection early and test manual clean, pause, and notification settings before relying on it.
- Run several supervised cycles first so multi-cat households can confirm every cat is comfortable with the motion and sound.
Care and setup notes
- Empty the waste bag before it is tightly packed so sealing stays quick and low-mess.
- Brush away litter dust from the seal strip and sensor ring during weekly maintenance to preserve odor control.
- Keep the included litter mat and surrounding floor edges clean so the open-top convenience does not turn into extra tracking cleanup.

“I have used every self cleaning litter box out there – the common manual ones where you have a sifting tray or you roll the litter box over to not so common which looked like some kind of dump truck system you had to crank”

“Long but worth the read to know how to get your cats to use it. I chose this automatic litter box because of the open top. I have a male sphynx who has a long body and weighs 10 lbs and I also have a small female sphynx who weighs 6 pounds”

FAQ
Why is the open-top design such a big selling point?
Open-top entry gives cats more visibility and personal space, which can make the transition easier for larger breeds, cautious cats, and households replacing a standard open litter pan.
Is the M1 Plus suitable for large cats or multiple cats?
Yes. This model is positioned for larger cats and multi-cat homes, with support for pets up to 33 pounds and a waste-bin capacity that reduces how often you need to empty it.
What makes this feel more premium day to day?
The stronger safety sensing, upgraded odor and anti-leak sealing, pull-and-wrap waste handling, and app-based habit tracking create a cleaner ownership routine than many budget automatic boxes.
