The Neakasa M1 is an open-top automatic litter box designed to reduce daily scooping. It uses infrared and weight sensors to detect cats, sift clumps after use, and move waste into a large sealed drawer.
Neakasa M1 — Best open-top self-cleaning litter box
The M1 combines an open entrance with automatic cleaning, app controls, and an 11.23-litre waste drawer. Its spacious design may be easier for large, senior, or cautious cats to approach than a fully enclosed automatic box.
- 【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.

Key features
Sensor-controlled cleaning
The M1 uses infrared and weight sensors to detect when a cat is inside or near the unit. The cleaning cycle pauses when movement is detected.
Open-top design
The rotating section never fully closes, reducing the enclosed feeling found in many automatic litter boxes and making entry easier for larger cats.
Large waste drawer
The 11.23-litre drawer may hold up to about two weeks of waste for one cat. Multi-cat homes will normally need to empty it more frequently.
Pull-and-wrap disposal
The bag can be pulled closed around the collected waste, helping make disposal cleaner and contain odours.
App monitoring
The app displays cleaning cycles, litter levels, waste-bin status, and usage patterns. Changes in litter-box habits can be useful to notice, but the app does not replace veterinary advice.
Litter compatibility
Use fast-clumping granular litter such as bentonite or mineral clay. Avoid wood pellets, newspaper litter, and loose non-clumping litter that may not pass through the sifting system correctly.
Alternatives

MeoWant 75L Self-Cleaning Litter Box — Best value for multiple cats
The MeoWant offers a spacious 75-litre interior, app controls, automatic cleaning, and an open entrance that may be easier for larger cats to use. Its waste drawer is smaller than the Neakasa M1’s, so it may need emptying more often in multi-cat homes.

FEELNEEDY S20 Self-Cleaning Litter Box — Best enclosed budget option
The FEELNEEDY S20 uses an enclosed design with app controls, sensor-based cleaning, and a large waste drawer. It is a practical alternative for cats that are already comfortable using covered litter boxes.
- 【Self-Cleaning & Zero Scooping】: Say goodbye to daily hand scooping! Our self-cleaning litter box activates within 2 minutes after your cat exits, separates waste, and deposits it into a trash bin. Compatible with clumping litter, bentonite litter, mineral litter, and tofu litter. Enjoy a fresh home and zero scooping even with 10-14 days of extended use since an ample 11L trash bin
- 【Advanced No Smell System】: Our self cleaning litter box adopts a triple-layer defense system to keep your home consistently fresh and odor-free. First, the integrated ABS material prevents urine leaks and traps odors at the source. At the same time, the 3-layer waterproof cat litter mat (non-stick design) outperforms standard silicone mats by resisting waste buildup and odor absorption. Finally, the airtight waste storage (with silicone gasket) ensures smells stay sealed in—0 escapes. Enjoy real odor-free living
- 【Multi-Layer Safety Protection】: Engineered for modern pet parents. We have designed an infrared sensor at the trash bin port. If your cat probes into the trash bin port out of curiosity during the cleaning cycle, the ball cabin will immediately stop rotating and return to the maximum opening state to prevent the cat from being trapped. If your cat enters the litter box, it instantly pauses cleaning because it senses the weight
FAQs
How often should the waste drawer be emptied?
Neakasa advertises up to about 14 days for one cat. Homes with several cats should check and empty the drawer more frequently.
Is the M1 suitable for large cats?
The manufacturer recommends it for cats weighing approximately 2.2 to 33 pounds. Its open-top design also provides more headroom than many enclosed models.
Can kittens use it?
Kittens weighing less than 2.2 pounds should use Kitten Mode with automatic cleaning disabled. Only start a manual cleaning cycle after checking that the kitten is away from the machine.
What litter works best?
Fast-clumping clay or mineral litter works best. Avoid non-clumping litter, wood pellets, newspaper litter, and particles that are too large for the sieve.
Will it work without Wi-Fi?
The box can perform basic functions without an internet connection, but remote app monitoring and controls require Wi-Fi.
What happens during a power outage?
Automatic cleaning will stop until power returns. The open basin can still be used, but waste will need to be removed manually.
Does it completely eliminate odours?
No litter box can guarantee an odour-free room. The sealed waste drawer and bags help contain smells, but regular emptying, cleaning, and suitable litter are still necessary.
Final verdict
The Neakasa M1 is a strong choice for cat owners who want automatic cleaning without a cramped enclosed entrance. Its open top, large waste drawer, sensor system, and app controls make it especially appealing for large cats and multi-cat homes.
Choose the PetSafe SmartSpin for a more compact design, the Litter-Robot 4 for a premium multi-cat system, or the FEELNEEDY S20 for a lower-cost enclosed alternative.
