Head-to-head # Neakasa M1 vs Litter-Robot 4: Open-Top or Globe? Updated November 12, 2026 By [Self-Cleaning Litter Box Guide Editorial Team](https://selfcleaninglitterboxguide.com/about/) [How we research](https://selfcleaninglitterboxguide.com/how-we-research/) Prices are approximate and change often, so check the current price before you buy. ## Key takeaways - The **Neakasa M1** is an open bowl with no hood, rated from 2.2 to 33 lb, for about $360–450. The **Litter-Robot 4** is a hooded globe rated from 3 to 25 lb and up to four cats, for about $699–749. - In Tom's Guide's test, cats used the **M1 51 times in a week** and the **Litter-Robot 4 30 times**. That's one household's preference, not a cleaning score, but it suggests the open top is easy for cats to accept. - The M1's weak spots are **litter scatter** and its history: WIRED didn't recommend the original M1 over safety, sensor and counterfeit concerns, and picked the **M1 Plus** instead. - Buy any M1 from a listing sold by Neakasa. Neakasa has published a warning about fake M1 listings. - Over five years with one cat, our default assumptions put the M1 at about **$960** and the LR4 at about **$1,580**, box included. ## Our top picks - 1![Neakasa M1 Open-Top Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/_astro/neakasa-m1.BQlFduq4_Z2r5bH9.webp)Best for very large cats and hood-haters: open top, 2.2–33 lb, about $360–450[Neakasa M1 Open-Top Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/litter-boxes/neakasa-m1/)Open-top · 2.2–33 lb · cats: not stated8.3**$$**$$Mid-rangePrice tier: Mid-range[Check price on Amazon](https://www.amazon.com/dp/B0DP8XYYKC?tag=selfcleaninglitterboxguide.com-20) - 2![Whisker Litter-Robot 4](https://selfcleaninglitterboxguide.com/_astro/whisker-litter-robot-4.CZhanV3w_12M27U.webp)Best for multi-cat homes and less mess: up to four cats, laser and weight sensors, about $699–749[Whisker Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/)Rotating globe · 3–25 lb · up to 4 cats8.7**$$$**$PremiumPrice tier: Premium[Check price](https://www.amazon.com/dp/B0BH6MD3DJ?tag=selfcleaninglitterboxguide.com-20) - 3Cheaper open-top for small and medium cats: about $250[Lesure Open-Top Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/litter-boxes/lesure-open-top/)Open-top · 3.3–18 lb · cats: not stated8.0**$**$$$BudgetPrice tier: Budget[Check price](https://www.amazon.com/dp/B0GJ5BMVFS?tag=selfcleaninglitterboxguide.com-20) ### On this page 15 sections - [Neakasa M1 vs Litter-Robot 4 specs](#neakasa-m1-vs-litter-robot-4-specs) - [Open-top vs globe: how they work](#open-top-vs-globe-how-they-work) - [What Tom’s Guide’s usage counts show](#what-toms-guides-usage-counts-show) - [Large cats](#large-cats) - [Scatter and mess](#scatter-and-mess) - [Odor and emptying](#odor-and-emptying) - [Safety](#safety) - [The original M1’s problems and counterfeit listings](#the-original-m1s-problems-and-counterfeit-listings) - [M1 vs M1 Plus vs M1 Lite](#m1-vs-m1-plus-vs-m1-lite) - [Apps](#apps) - [Reliability](#reliability) - [Running costs](#running-costs) - [Who should buy which](#who-should-buy-which) - [Verdict](#verdict) - [FAQ](#faq) ## Before you choose - [The Best Open-Top Self-Cleaning Litter Boxes of 2026](https://selfcleaninglitterboxguide.com/posts/best-open-top-self-cleaning-litter-box/) - [The Best Self-Cleaning Litter Box for Large Cats in 2026](https://selfcleaninglitterboxguide.com/posts/best-self-cleaning-litter-box-for-large-cats/) - [Litter-Robot Alternatives That Are Worth It (and Two to Skip)](https://selfcleaninglitterboxguide.com/posts/litter-robot-alternatives/) The [Neakasa M1](https://selfcleaninglitterboxguide.com/litter-boxes/neakasa-m1/) and the [Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/) solve the same problem in opposite ways. The M1 is an open bowl with no hood, rated for cats from 2.2 to 33 lb, for about $360–450. The Litter-Robot 4 is a hooded globe rated from 3 to 25 lb and up to four cats, for about $699–749. Pick the M1 for a very large cat or one that refuses hooded boxes. Pick the Litter-Robot 4 for several cats and a cleaner floor. We haven’t tested either box ourselves. This comparison uses Neakasa’s and Whisker’s published specs, Amazon listing text, and hands-on results from Tom’s Guide and WIRED, and we name the outlet each time. Prices are typical street prices from dated sources, not live Amazon prices, so check today’s price before you buy. ## Neakasa M1 vs Litter-Robot 4 specs | | [Neakasa M1](https://selfcleaninglitterboxguide.com/litter-boxes/neakasa-m1/) | [Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/) | | --- | --- | --- | | Typical price | About $360–450 (Lite about $332) | About $699–749 | | Design | Open-top bowl | Hooded rotating globe | | Cat weight (maker) | 2.2–33 lb | 3–25 lb | | Cats per unit | No number given | Up to 4 | | Opening | Open top; entry height 13.86 in (Neakasa); WIRED measured the M1 Plus opening at 17 × 16.5 in | 15.75 × 15.75 in, 16.5 in interior height | | Footprint | 23 × 21 in, 22 lb | 22 × 27 in, about 29.5 in tall, 24 lb | | Sensors | 5 infrared pairs + 4 weight sensors (Plus: 6 pairs) | Laser curtain + weight sensors | | Waste bin | 11.23 L, up to 14 days for one cat | As rarely as every 8 days (Whisker) | | Litter | Bentonite or clay clumping | Standard clumping clay | | Small kittens | Kitten Mode under 2.2 lb | Semi-automatic under 3 lb | | Noise (maker) | About 50 dB | Not published in our sources | | Warranty | 1 year (M1 listing) | 1-year WhiskerCare; 3-year extended plan available | For every box side by side, see the [comparison chart](https://selfcleaninglitterboxguide.com/litter-boxes/). ## Open-top vs globe: how they work The Litter-Robot 4’s globe rotates slowly after each visit. Clumps drop through a screen into a sealed drawer underneath, and clean litter returns to the bed. The hood keeps litter inside, and the entry stays open throughout. The M1 has no hood. It’s an open bowl that tilts or rotates to sift clumps into the bin below. Tom’s Guide notes it also flips the container to dislodge stuck clumps. With no roof and no door, there’s nothing for a cat to squeeze through, and nothing to close. Four ways a litter box cleans itself The mechanism decides how safe, how messy and how expensive to run a box is. Rotating globeThe whole globe turns slowly after each visit, sifting clumps through a screen into a drawer below. The best-known design (Litter-Robot). Large entries, but a tall unit. Litter-Robot 4, 5, EVO Tilting drumA drum on a base tilts or turns part-way to sift, then returns. Most PETKIT and many Amazon brands. Good ones keep the entrance open the whole time. PuraMax 2, Purobot, Leo's Loo Too, SmartSpin Open-topAn open pan that flips or rotates to dump clumps. No hood to squeeze through and no door to close; more litter scatter. Neakasa M1, Lesure Rake + crystal trayA rake sweeps waste into a covered trough on a disposable crystal tray. Nothing encloses the cat, but you buy trays forever. ScoopFree Crystal Smart, Classic Avoid designs with a door or a front that closes during cleaning: if a sensor fails, a cat can be trapped. More in [are self-cleaning litter boxes safe?](https://selfcleaninglitterboxguide.com/posts/are-self-cleaning-litter-boxes-safe/) That one difference drives most of the trade-offs below: the M1 is more open for the cat and messier for you. ## What Tom’s Guide’s usage counts show Tom’s Guide’s John Velasco tracked how often his cats used each of four robotic boxes. In one week, they used the Neakasa M1 51 times and the Litter-Robot 4 30 times. The LR4’s count was almost triple that of Leo’s Loo Too. Read that carefully. It’s one household’s cats over one week, so it measures preference, not cleaning quality or safety. Still, preference matters. A box your cat avoids does nothing for you, and it’s a sign the cat is going somewhere else. For a cat that has refused a hooded box before, the M1 is the better bet. Whisker, for its part, claims “over 95% of cats acclimate” to the Litter-Robot 4, based on its return reasons. Whichever you choose, keep the old box out until your cat uses the new one reliably. Our [transition guide](https://selfcleaninglitterboxguide.com/posts/how-to-transition-cat-to-automatic-litter-box/) covers the steps. ## Large cats This is the M1’s strongest case. Neakasa recommends it for cats from 2.2 to 33 lb and says the open top has almost no hard weight limit. WIRED measured the M1 Plus’s opening at 17 × 16.5 in. There’s no ceiling for a tall cat to hunch under. The Litter-Robot 4 is no slouch. Its 15.75 in square entry and 16.5 in interior height fit most large breeds, and Whisker rates it to 25 lb. Above that, the M1 or the [Litter-Robot 5](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-5/) (rated to 30 lb) are the options. One thing to check for older cats: Neakasa lists the M1’s entry height as 13.86 in, so look at how high your cat will need to step before you buy. Run your cat through the [safety checker](https://selfcleaninglitterboxguide.com/tools/cat-safety-checker/#weight=22&model=neakasa-m1) with their weight and mobility, and see our [large-cat guide](https://selfcleaninglitterboxguide.com/posts/best-self-cleaning-litter-box-for-large-cats/). ## Scatter and mess The open top has a cost. Tom’s Guide found the M1’s open design scatters litter, though the box includes a netted mat. WIRED also flagged scatter on its M1 Plus. Plan on a big mat such as the [Gorilla Grip 40 × 28 in](https://www.amazon.com/dp/B08QNCB6YF?tag=selfcleaninglitterboxguide.com-20) or the [iPrimio jumbo mat](https://www.amazon.com/dp/B01AUU90IW?tag=selfcleaninglitterboxguide.com-20), and a quick daily sweep. The Litter-Robot 4’s hood keeps more litter inside, and Whisker sells its own LitterTrap mat ($50). Our [mats and supplies](https://selfcleaninglitterboxguide.com/accessories/) page compares options. ## Odor and emptying Neakasa claims an 11.23 L bin that lasts up to 14 days for one cat. WIRED’s experience with the M1 Plus was shorter: it could smell waste after about five days, and wet litter stuck to the back grate. The Litter-Robot 4 uses a sealed drawer with a carbon filter and optional OdorTrap packs, which Whisker says to replace every 2–4 weeks. Whisker says the drawer may need emptying as rarely as once every 8 days. Tom’s Guide noticed the LR4 could keep cycling after the app said the bin was full, so empty it on schedule. Our [odor fixes](https://selfcleaninglitterboxguide.com/posts/self-cleaning-litter-box-odor-fixes/) apply to both. ## Safety Both boxes pass the first test: nothing closes on the cat. The M1 has no hood or door. The Litter-Robot 4’s entry stays open while the globe turns, and WIRED only recommends boxes that stay open during cycling. Sensing differs. Neakasa uses five pairs of infrared sensors and four weight sensors on the M1, and six infrared pairs on the M1 Plus. Whisker pairs a laser curtain with weight sensors. For small cats, the M1’s 2.2 lb minimum is lower than the LR4’s 3 lb. Below those weights, both makers say to stop automatic cleaning: Neakasa’s Kitten Mode turns it off, and Whisker says to run the LR4 in semi-automatic mode, powered off and cycled by hand. See our [kitten guide](https://selfcleaninglitterboxguide.com/posts/best-self-cleaning-litter-box-for-kittens/). ## The original M1’s problems and counterfeit listings WIRED didn’t recommend the original M1 because of controversies over safety, faulty sensors and counterfeit models. It picked the upgraded M1 Plus as its best open-top box instead, citing an improved app, a kitten mode and support for cats from 2.2 lb up to 33 lb. Counterfeits are a separate, ongoing problem. Neakasa published a notice, updated June 22, 2026, warning about fake M1 listings and fraudulent sellers. To protect yourself: - Buy from a listing sold by Neakasa or its official storefront. - Check the seller name, not just the product title. - Be wary of a price far below the usual $330–450 range. - Check the version. The standard M1 listing we link is not the M1 Plus. ## M1 vs M1 Plus vs M1 Lite | Version | Typical price | What’s different | | --- | --- | --- | | [M1 Lite](https://www.amazon.com/dp/B0DK6RSFG2?tag=selfcleaninglitterboxguide.com-20) | About $332 | No bottom gate, no mat included (Amazon listing) | | [M1](https://www.amazon.com/dp/B0DP8XYYKC?tag=selfcleaninglitterboxguide.com-20) | About $380 | 5 infrared pairs + 4 weight sensors, 11.23 L bin, 1-year warranty | | [M1 Plus](https://www.amazon.com/dp/B0CSKBWBF6?tag=selfcleaninglitterboxguide.com-20) | About $430–450 | 6 infrared pairs, upgraded odor-sealing brush strip, improved app; listing title advertises a 2-year protection plan | Our pick is the M1 Plus if the price gap is small on the day, since it’s the version WIRED tested and recommended. The Lite’s missing mat matters more than it sounds on an open-top box. ## Apps WIRED likes Whisker’s app, which tracks visits and weight and warns about litter level and drawer status. Tom’s Guide found it tells cats apart by weight. WIRED found Neakasa’s app poorly translated, with no multi-cat history. It said the M1 Plus app is improved. If you track multiple cats’ visits for health reasons, the Litter-Robot 4 is the stronger tool. ## Reliability The Litter-Robot 4 has a long test record with known flaws. WIRED’s unit sometimes sensed “ghost cats” and reported a full drawer when half full after nearly two years. Tom’s Guide’s unit, used for more than a year, was still holding up but sometimes squeaked, so it needs regular maintenance. The M1’s track record includes the original model’s faulty-sensor complaints noted by WIRED. Our [troubleshooting guide](https://selfcleaninglitterboxguide.com/posts/automatic-litter-box-troubleshooting/) covers common fixes for both. ## Running costs With our default assumptions (about 10 lb of clumping litter per cat per month at $0.57 a pound), one cat costs about $121 a year in an M1 and about $177 in a Litter-Robot 4. Over five years, box included, that’s about $960 against $1,580. The M1 figure uses a $1-per-bag stand-in price, and [generic bags that fit the M1](https://www.amazon.com/dp/B0F1MVCSX5?tag=selfcleaninglitterboxguide.com-20) may be cheaper. Neakasa also sells its own [mineral litter](https://www.amazon.com/dp/B0DD7K98WS?tag=selfcleaninglitterboxguide.com-20).

It’s about half the price of a Litter-Robot 4, its range runs to 33 lb, and Tom’s Guide’s cats chose it most often. Accept the scatter, buy a big mat and purchase only from a listing sold by Neakasa. Buy the Litter-Robot 4 if you have several cats, want a cleaner floor and value Whisker’s app and support. It’s rated for up to four cats, uses a laser curtain plus weight sensors, and held up through more than a year of use at Tom’s Guide, with the caveats WIRED found as it aged.

It's better for some cats. The M1 is open-top, rated up to 33 lb and about half the price, and Tom's Guide's cats used it more than any other box in its test. The Litter-Robot 4 is rated for up to four cats, contains litter better, has a laser curtain plus weight sensors and the app WIRED likes. For very large cats or cats that hate hoods, the M1. For multi-cat homes and less mess, the Litter-Robot 4. ### What's the difference between the Neakasa M1, M1 Plus and M1 Lite? The M1 Lite (about $332) drops the bottom gate and the mat, per its Amazon listing. The standard M1 (about $380) has five pairs of infrared sensors and four weight sensors. The M1 Plus (about $430–450) adds a sixth infrared pair, an upgraded odor-sealing brush strip and an improved app; it's WIRED's best open-top pick. ### Is the Neakasa M1 safe? The open top means there is no hood or door to close on a cat, and Neakasa uses infrared and weight sensors to pause cleaning. WIRED didn't recommend the original M1 because of controversies over safety, faulty sensors and counterfeit models, and recommends the M1 Plus. Below 2.2 lb, Neakasa says to use Kitten Mode with automatic cleaning off. ### How do I avoid a counterfeit Neakasa M1? Neakasa has published a notice, updated June 22, 2026, warning about fake M1 listings and fraudulent sellers. Buy from a listing sold by Neakasa or its official storefront, be wary of prices far below the usual $330–450 range, and check the seller name before you check out. ### Does the Neakasa M1 make a mess? More than a hooded box. Tom's Guide found the open design scatters litter, though the M1 includes a netted mat. WIRED also flagged scatter and found wet litter stuck to the back grate of its M1 Plus. Put a large mat under it and expect to sweep. ## Sources - [Tom's Guide: I asked cats to test these robotic litter boxes](https://www.tomsguide.com/home/smart-home/my-cats-have-tested-these-robotic-litter-boxes-for-months-heres-the-one-they-use-the-most) · checked 2026-11-12 — Cats used the Neakasa M1 51 times in one week and the Litter-Robot 4 30 times; the M1 scatters litter, includes a netted mat and flips the container to dislodge stuck clumps; the LR4 has held up for over a year but sometimes squeaks. - [WIRED: The Best Automatic Litter Boxes](https://www.wired.com/gallery/best-automatic-cat-litter-boxes/) · checked 2026-11-12 — Neakasa M1 Plus is the best open-top pick; WIRED didn't recommend the original M1 over safety, faulty-sensor and counterfeit concerns; wet litter stuck to the M1 Plus's back grate and waste could be smelled after about five days. - [Neakasa: M1 product page](https://neakasa.com/products/neakasa-m1-cat-litter-box) · checked 2026-11-12 — 2.2–33 lb recommended; Kitten Mode under 2.2 lb; 5 IR pairs and 4 weight sensors; 11.23 L bin up to 14 days; about 50 dB; entry height 13.86 in. - [Neakasa: Beware of fake Neakasa M1 listings](https://neakasa.com/blogs/news-and-events/important-notice-beware-of-fake-neakasa-m1-listings) · checked 2026-11-12 — Neakasa warns of fraudulent sellers and counterfeit M1 listings (updated June 22, 2026). - [Whisker: Litter-Robot 4](https://www.litter-robot.com/litter-robot-4.html) · checked 2026-11-12 — 3–25 lb, up to 4 cats, 15.75 × 15.75 in entry, 16.5 in interior height, laser and weight sensors, $699. - [Amazon: Neakasa M1 listing](https://www.amazon.com/dp/B0DP8XYYKC?tag=selfcleaninglitterboxguide.com-20) · checked 2026-11-12 — The standard M1, not the M1 Plus; 5 IR pairs and 4 weight sensors; up to 14 days between emptying; 1-year warranty. - [Amazon: Neakasa M1 Plus listing](https://www.amazon.com/dp/B0CSKBWBF6?tag=selfcleaninglitterboxguide.com-20) · checked 2026-11-12 — M1 Plus with 6 IR pairs, $429.99 in the listing's comparison table. ## Get new guides by e-mail One short e-mail when Self-Cleaning Litter Box Guide publishes a new guide.
