The Best Automatic Litter Boxes of 2026: 10 Picks Compared Side by Side

What works

• In the Agnes The Tuxedo YouTube review (a June 2025 affiliate video of a Coziley G1 bought through an earlier white listing, so we cannot confirm identical hardware), both of the owner's cats used the box within 24 hours, and the cycle stopped at once whenever one cat stood half in and half out.
• The manual says the weight sensor treats a change of 2.5 lb or more as a cat, pauses a running cycle and restarts it 5 seconds after the cat leaves; an infrared sensor at the waste outlet stops the globe if a cat puts its head there.
• The globe unclips into two halves and the sifter, litter saver and floor pad come out for washing, which Agnes The Tuxedo found easier to deep clean than a Litter-Robot; the manual says to wipe the base only, never rinse it.
• Coziley's Amazon listing says it works with mineral, bentonite, mixed and plant clumping litters, and the manual recommends small-grain clumping litter.
• Spare parts are sold through the listing, including a G1 sifting screen ($27.99), litter pad ($29.99), power adapter ($22.99) and 120 waste bags ($26.99); Agnes The Tuxedo said small kitchen bags also fit the drawer.

What does not

• We found no lab or editorial test of this model from any outlet: the only hands-on coverage is two affiliate YouTube videos with no measurements, and one of them (Technically Jeff) covers a ZHMZ-branded G1, not a Coziley unit.
• The health monitoring in the title is thin: Coziley advertises cat activity monitoring but never claims weight tracking, Agnes The Tuxedo found the app logs visits and their length but does not weigh cats or tell them apart, and the manual's app section lists only litter level, child lock, weighing reset, light, sound and kitten mode.
• Noise claims do not agree: the listing bullets say the cycle runs silently and an A+ image says 30 dB, while Agnes The Tuxedo, though she called it relatively quiet, could hear a low hum from another room and compared it to a running dishwasher.
• Coziley's images promise 7 days without scooping from a 12 L drawer, but Agnes The Tuxedo empties it twice a week and says odor can build after a week; Technically Jeff, testing the ZHMZ-branded G1, found a little urine around the front when emptying the bin.
• There is no empty cycle, so a full litter change means lifting off the bonnet and turning the globe by hand to dump the litter, per the manual and Agnes The Tuxedo.

Who is it for

Owners of a cat or two between 2.5 and 18 lb who want a globe-style box with basic app control for around $210 on sale (list $299). It suits buyers who can lean on Amazon's 30-day return window and do not mind emptying the drawer a couple of times a week.

Who is it not for

Skip it if you want real health tracking such as per-cat weight, since the app only logs visits and their length, or if you need a confirmed UL or ETL safety listing. Very large cats are a stretch: the listing caps it at 18 lb, and Technically Jeff's 22 lb cat fit only tightly in the ZHMZ-branded sibling.

What works

• PetPivot's manual rates the waste drawer at 10 L (2.64 gal), larger than the 8 L drawer in its newer AutoScooper 12 Lite, and asks single-cat owners to empty it every 5 days and never later than 7.
• There is no app, Wi-Fi or account: three buttons run an automatic mode, a manual mode for small or young cats and a child lock, per the manual and The Gadgeteer.
• The Gadgeteer found assembly needed no tools and called setup very easy, and it liked having both automatic and manual cleaning modes.
• The drawer takes drawstring liners that you pull shut before opening it, to keep odor in, and the litter chamber lifts out to be rinsed, per the manual.
• PetPivot sells spare parts for this model on its own store, including a replacement drawer ($28.99), two support legs ($18.89) and rear latches ($9.99), though its 12 V, 2 A adapter ($19.99) showed as out of stock when we checked.

What does not

• The Gadgeteer's two cats never used the box during its test and still had not taken to it at a September 2025 update, so the one independent test produced no cleaning, odor or noise results.
• Published specs conflict: the manual gives 32 dB while PetPivot's product page says 38 to 40 dB, and The Gadgeteer quoted a 7.9 L litter capacity against 6.5 L (1.72 gal) in the current manual.
• Amazon's bullets say the drawer suits single-cat households while the same listing's title and PetPivot's page pitch it for multi-cat homes, and PetPivot gives no maximum number of cats.
• The Gadgeteer found the waste bags fit the drawer poorly, took the spare back latch in the box as a sign PetPivot expects that part to break and noted the box restarts in automatic mode after a power cut rather than its last setting.
• It cannot use tofu-strip or crystal litter, and both the manual and an owner review on PetPivot's page say that once the drawer is full the chamber stays closed until it is emptied.

Who is it for

Owners of one or two average-size cats who want an app-free, open-top box and value the larger 10 L drawer of PetPivot's older model. It suits buyers willing to rely on PetPivot's own specs, since no outlet has measured how well it cleans.

Who is it not for

Skip it if your cat is wary of new boxes, since The Gadgeteer's two cats never used it, or if you want tofu or crystal litter. It is also a weak pick if you want third-party test results or a confirmed electrical safety listing before buying.

What works

• Les Alexiens, testing with three cats, measured about 35 dB(A) during a cleaning cycle and found odors well contained, reporting it could go about 15 days between bin emptyings without nuisance.
• The redesigned sealed drum base held up in testing: Les Alexiens saw no leaks when cats urinated on the drum wall, and Cats.com's liner held when a cat urinated a large amount at the very back.
• Galaxus's reviewer found it sifted reliably after every visit, about a quarter of an hour after the cat left, with a coarser wood-fiber litter, because PETKIT includes two swappable sifters.
• Cats.com found it needed very little assembly, the app was easy to pair and navigate, daily scooping worked as it should, and it scored odor control 4 out of 5.
• AutoLitterBox.co.uk, a UK affiliate site, testing eight weeks with two cats, timed the cleaning cycle at about 2 minutes and found the sealed bin plus the N50 odor eliminator controlled smell in a small flat without the optional spray.

What does not

• Emptying old litter is weak: Cats.com found the magnetic litter remover left a lot of litter behind even after multiple runs, gave up after two attempts and finished with a vacuum, scoring ease of cleaning 3 out of 5.
• Galaxus found clumped litter sticks to the rough litter pad, so residue has to be scraped off by hand, and the long, low waste bin piles clumps in one spot.
• Days between emptying vary: the Amazon listing claims up to 15 days, Les Alexiens says it can go about 15 days with three cats, but AutoLitterBox.co.uk emptied the drawer every 5 to 6 days with two cats.
• Big cats may not take to it: the Amazon listing claims cats up to 22 lb, but Cats.com's cats over 10 lb ignored it, and Amazon's review summary says some owners find it too small for large cats.
• Galaxus found the safety sensor blocked manually started cleanings far too often, and AutoLitterBox.co.uk needed three attempts and a router restart to pair it, then saw the app show offline about every 10 days.

Who is it for

Homes with one to three adult cats of average size, on a hard floor, that want a sealed, camera-free drum box which keeps cleaning even when the Wi-Fi drops. It suits owners who already use a clumping clay, tofu or wood litter and want per-cat weight and visit logs in an app.

Who is it not for

Skip it for kittens under 6 months or cats under 3.3 lb, for very large cats, or if the box has to sit on carpet or a mat, which PETKIT says interferes with the sensors. It is also a poor fit if you want easy full litter changes, since Cats.com found the emptying tool left much of the litter behind and finished the job with a vacuum.

What works

• iHeartCats, testing the M1 Plus with seven cats, found clump separation worked very well, reported no lingering smell and could not hear a cycle from another room.
• Catster's one-year-old kitten interrupted the first cleaning cycle about thirty times on the original M1, and the box froze every time without pinching or trapping him.
• CGMagazine found the original M1 used less litter than its previous setup and noticed smell only after fresh litter went in or just before a cycle.
• The open top suits big cats: Neakasa rates it for cats up to about 33 lb with a 13.86 in entry height, and Amazon says it supports up to 3 cats, with the app tracking each one separately.
• Upkeep is cheap: the box needs no carbon filters or deodorizing packs per Amazon, Neakasa says any bag that fits the drawer works, and 30 branded refill bags cost $19.99 on Amazon.

What does not

• No major outlet has tested the M1 Plus; the iHeartCats and cleveland.com accounts gave no measurements, and the iHeartCats page carries a Neakasa discount code for its readers.
• A Neakasa notice (last updated June 2026) made firmware 1.0.7-0019 mandatory on the M1 after a dislodged liner magnet could let the chamber over-rotate, and a Galaxus forum post passed on an unverified, second-hand Facebook report of a kitten being hurt.
• Days between emptying vary by source: Amazon says 7 to 14 days, Neakasa's FAQ says about 14 for one cat, its own M1 manual says 7 to 10 days and 7 in summer, and Neakasa's blog now advises emptying weekly.
• Cats.com relayed M1 owners' reports of smeared waste, urine leaking at the liner seam and false bin-full alerts, and Amazon's review summary also flags a bin reporting full when empty and litter getting everywhere.
• The 13.86 in entry is tall for small, old or stiff cats: CGMagazine said bigger cats may struggle to climb in, Cats.com's senior cat refused it, and iHeartCats suggested the optional step to catch more litter.

Who is it for

Owners of large or wary cats who dislike hooded or globe boxes and want an open tray that empties itself into a bag. It also suits multi-cat homes that want per-cat visit logs on a phone and are happy using fine clumping clay litter.

Who is it not for

Skip it if your cat is a small kitten, a senior or has trouble climbing, since the entry is almost 14 in high and Kitten Mode turns automatic cleaning off. It is also a poor fit if you want lab-tested proof of this exact version or use pellet, paper or non-clumping litter.

What works

• Catster's veterinarian reviewer, testing with five cats in a paid partnership with PetPivot, found all five chose it over their old enclosed box and measured 6.4 lb (2.9 kg) of soiled litter and waste in its drawer after a week alongside another automatic box.
• Gadget Flow, which bought its unit, could take Zoom calls while it cycled, its two cats were not startled, and it noted the half-gear design always leaves a visible gap so a cat cannot be shut in.
• Cats.com, whose photos show this step-equipped model, scored its odor control 5 out of 5 after several weeks of use and saw two medium-size cats step in within minutes.
• Catster saw the cycle pause at once when anything moved near the one cat-size gap that opens late in the cycle, and liked that the drawer slides out the front with the step latched to it.
• It needs no app, Wi-Fi or subscription, and PetPivot backs it with a 30-day return window and a 1-year limited warranty, and sells spare drawers ($26.99) and litter-bed pads on its store.

What does not

• The tray is about 12 by 14 inches per Catster, and Cats.com's 17 lb cat could not turn around comfortably, so it is tight for large breeds.
• Emily Reviews, testing a free unit with one cat for about six weeks, found the noise the hardest part of her cat's adjustment, saw poorly formed clumps smear as the drum turned and sometimes caught an odor while a clump was being moved.
• Sensor counts conflict: Amazon says 7 pairs of infrared sensors and a PetPivot press release says seven, while PetPivot's product page says 6 pairs plus 4 Hall sensors; noise also differs, with Catster citing 32 dB (the AS11 manual's figure) against 38 to 40 dB in the AS12 manual.
• Catster found its sensor less sensitive than her other automatic box, and litter and debris collect where the liner meets the unit and have to be brushed out.
• Gadget Flow found a deep clean takes about 15 minutes of disassembly and scrubbing, and its cats batted the DC power plug loose until it clipped the cable to the wall.

Who is it for

Homes with up to three average-size cats, including older cats that benefit from the removable step, that want automatic scooping with no app or subscription at its $139.97 Amazon price (October 24, 2026). It suits owners happy to use clumping clay litter and swap a bag every five to seven days.

Who is it not for

Skip it for large breeds such as Maine Coons, since Catster and Cats.com both found the tray tight for big cats. It is also a poor fit if you want tofu or crystal litter, app alerts, or a confirmed UL or ETL safety listing.

What works

• In Cats.com's several-week home test, the PurrTek scored 5 out of 5 for odor control, and the reviewer found the waste bags held smells well, helped by the fan and negative ion cycle after each clean.
• Cats.com described the rotation as slow and fairly quiet, and the unit arrived fully assembled, matching Petcove's claim that you just plug it in and add litter.
• Safety relies on weight sensors in the four feet plus an infrared sensor on the control panel, and the manual says cleaning and deodorizing pause when a cat approaches or enters and resume after it leaves.
• The waste bag never has to be handled loose: a bag-change cycle turns the drum 90 degrees so the bag mouth faces up, then you pull the drawstring and toss it, per the manual.
• The drum has no electronics and lifts out to be washed in warm soapy water, and the app lets you set the clumping delay from 0 to 60 minutes and the gap between cleans from 0 to 120 minutes, per the manual.

What does not

• Cats.com's reviewer said they do not recommend it because of the manual cleaning it still needs, and found the rubber litter pan bottom hard to wash.
• Cats.com found the app setup difficult: the QR code led to a blank page, the app's directions did not match the manual, and the box was hard to find among Petcove's other devices.
• In the Cats.com test the rotations flung litter onto the floor, the entrance was small with a high step, and one cat never seemed comfortable getting in and out.
• Capacity claims do not agree: Petcove's product page says a 13 L drawer holds up to 15 days, while the manual lists a 2.5 gallon bin, says 15 days is for one cat but only 5 days for three, and advises a bag change at least every 5 days.
• Cats.com said the cord was short enough that an extension cord would likely be needed, yet the manual says not to use one, and the reviewer also reported no full-bin alert even though the manual describes a full-bin light.

Who is it for

One or two healthy adult cats between 3 and 17 lb that are comfortable in an enclosed box and use a quick-clumping clay or mixed tofu litter. It suits an owner who wants waste bagged out of sight and can place the unit on a hard floor with a foot of clear space around it.

Who is it not for

Skip it for cats over 17 lb, the manual's limit, and for kittens under 3 lb, whom the manual keeps off automatic cleaning; it also tells owners of senior cats to ask a vet first. It is also a poor choice if you use crystal or pine litter, or if you want a camera or a published test with measured results.

What works

• The step answers the tall 13.86 in entry that testers flagged: iHeartCats suggested adding it to catch more litter, Cats.com listed the step being sold separately as a con, and Neakasa recommends it for kittens and seniors.
• Per Amazon, the step's 0.5 cm grill and angled deflector catch litter falling from paws, the ABS top can be rinsed directly, and a spout lets you pour the collected litter back.
• On Oct 24, 2026 the bundle cost $36.99 more than the box alone ($436.98 against $399.99), less than the $56.99 the bundle breakdown lists for the step on its own.
• iHeartCats found the M1 Plus separated clumps very well with no lingering smell in a seven-cat home, and Catster saw the original M1 freeze each of the roughly thirty times its kitten climbed in mid-cycle.
• Running costs stay low after the included bags run out: refills are $19.99 for 30 on Amazon, Neakasa says any bag that fits works, and Amazon says no carbon filters are needed.

What does not

• The 30 bags and litter mat are not extras, since the box-only listing also includes a mat and 2 rolls (30 bags), and with the $20 coupon shown on that listing the two parts bought separately came to the same $436.98.
• Neakasa's own US store sold the M1 Plus and step bundle for $409.99 on Oct 24, 2026, below this Amazon bundle price.
• We found no independent test of the step itself, so its litter-catching and easier-entry claims rest on Neakasa and the Amazon listing, and the bundle has only 51 Amazon ratings.
• Neakasa made M1 firmware 1.0.7-0019 mandatory after a loose liner magnet could let the chamber over-rotate, and the M1 Plus's sweeping sensors and rotation-limiting gear have not been tested by any outlet.
• Cats.com passed on M1 owners' reports of smeared waste, seam leaks and false bin-full alerts, and Neakasa's own blog now advises emptying the bin weekly despite claims of up to 14 days.

Who is it for

Buyers set on the M1 Plus who have a kitten, a senior, a short-legged cat or a litter-tracking problem, and who would buy a step anyway. It suits homes that want the box, mat, bags and step in one order at no extra cost over buying them separately.

Who is it not for

Skip the bundle if your cats climb easily and you do not mind sweeping, since the box alone already includes the mat and 30 bags. It is also not the cheapest way to get this pairing if Neakasa's own store price is lower on the day you buy.

What works

• A tray-life LED stays blue for the first 50 rake cycles and turns yellow when it is time to change the tray, per PetSafe's Crystal Plus guide.
• The rake and waste trap cover lift out and can be washed with warm soapy water, according to the guide; the older Legacy has no removable rake per Amazon's comparison chart.
• The rake waits 20 minutes after the cat leaves, the countdown restarts if the cat comes back, and if a sensor is blocked mid-cycle the box stops and flashes yellow, per the guide.
• Mashable, whose household moved to the Crystal Plus in November 2025 after three years with the Legacy, says it works essentially the same as the older model, just without the scoop-counting screen.
• PetSafe's $49.99 stainless steel reusable tray is listed as compatible with Plus models and PetSafe says using it will not void the warranty.

What does not

• Only tagged PetSafe trays work: the guide says the box flashes red for an invalid tray and stops raking at 199 rake cycles until the tray is replaced, while Mashable says its unit refused to rake at 50 cycles.
• Mashable lists the Crystal Plus as finicky with PetSafe's reusable stainless steel tray, so the refill-it-yourself route may take some fiddling.
• There is no health counter and no hood option, per PetSafe's spec table and Amazon's comparison chart, so it cannot track visits or contain scatter the way the Legacy with its cover can.
• Mashable found its ScoopFree boxes start to smell before PetSafe's tray-change windows and need a light scoop every few days; PetSafe's guide itself rates a tray at 20 to 30 days for one cat, 10 to 15 for two and 7 to 10 for three or more.
• It costs $180.99 on Amazon ($199.99 on petsafe.com) against $129.99 for the Legacy, and it holds a 3.2 out of 5 Amazon rating from 145 ratings as of October 24, 2026.

Who is it for

A one-cat home that wants an open, traditional-shaped box that rakes itself, and an owner who likes a light telling them when to change the tray. It also suits someone who travels for a few days at a time and is fine paying for PetSafe trays.

Who is it not for

Skip it if you want to track your cat's visits, need a hood, or want to use clumping or third-party litter, since the box only runs on tagged PetSafe trays. Homes with two or more cats will be changing trays every one to two weeks, which gets expensive.

What works

• Mashable used this Legacy model for about three years, mostly with two cats, and rates the ScoopFree as almost never missing solid waste and leaving a smoothed bed of crystals.
• Its traditional litter box shape slid between Mashable's toilet and cabinets, and one of the reviewer's cats rejects big enclosed automatic boxes but keeps using the ScoopFree.
• The LCD health counter adds one each time the rake completes a cycle, including manual runs, and resets with a 3-second press, per PetSafe's 2nd Generation manual.
• It can take PetSafe's privacy cover or top-entry cover, sold as accessories in the manual's parts list, while Amazon's chart marks the Crystal Plus as not hood compatible.
• At $129.99 on Amazon it costs $51 less than the Crystal Plus, and Mashable says PetSafe's $49.99 stainless steel reusable tray, which PetSafe lists for all ScoopFree crystal systems, let it buy other brands of silica crystal litter instead of refills.

What does not

• Mashable found its ScoopFree started to smell earlier than any of PetSafe's tray-change windows and needed a light scoop every few days, adding that leaving it untouched for the 10 to 15 days PetSafe gives for two cats would not be bearable.
• It does not work with clumping litter: the manual bans clay, natural and other crystal litters in the disposable trays, and Mashable says dried urine clumps get too heavy for the rake.
• Listing claims are loose: an Amazon bullet calls the rake removable while Amazon's own chart says it is not, and the health counter logs rake cycles rather than every visit, since a return visit during the countdown restarts the timer.
• PetSafe's manual says it is best for cats under 15 lb and is not intended for disabled or very old cats, and kittens under 6 months should use it unplugged.
• After three years a plastic piece of the lifting lid on Mashable's unit snapped off, which the reviewer blames mostly on a cat that plays with it.

Who is it for

A one- or two-cat home with cats under 15 lb that wants a low, open box that rakes itself and a simple counter to watch for changes in litter habits. It suits budget buyers who want the option to add a hood later.

Who is it not for

Skip it if you want truly hands-off odor control for weeks with more than one cat, since Mashable needed to scoop lightly every few days. It is also a poor fit for very large, elderly or disabled cats, or anyone who wants to use clumping litter.
