By [Self-Cleaning Litter Box Guide Editorial Team](https://selfcleaninglitterboxguide.com/about/) · Updated November 12, 2026 · [How we score](https://selfcleaninglitterboxguide.com/how-we-research/) We haven't tested this box ourselves. Our score comes from maker specs and manuals, named hands-on reviews and owner reports; where a test result appears, we name the outlet. ## The verdict The Litter-Robot 5 has the highest cat count of any box here and the highest weight limit of any hooded box, plus Whisker's laser-and-weight safety system. Big Maine Coons and five-cat homes are covered. WasteID is a genuinely new health tool, but it needs a subscription and took months of firmware updates to settle down in WIRED's testing. Most one- to three-cat homes get the same core cleaning from a Litter-Robot 4 for less. ### What we like - Highest cat count here and the highest weight limit of any hooded box: up to five cats from 3 to 30 lb (Whisker) - Same 15.75 in entry as the LR4 with 1 in more headroom inside - WasteID separates urine and stool visits; WIRED saw it improve markedly after firmware updates - Holds about 10 days of waste from two cats in WIRED's testing ### Watch out for - $799 before Whisker+, which WasteID and cat ID need (about $80 a year, per WIRED) - WIRED found the touchscreen finicky and preferred the LR4's physical buttons - WasteID and weight-based cat ID worked only intermittently in WIRED's first four months - Amazon sells it only as a pricier bundle ## Score breakdown Cat safety 9.2 Cleaning & odor 9.1 Ease & reliability 8.2 Value 6.8 Rotating globe · cats 3–30 lb · Laser curtain, Weight ## Litter-Robot 5 specs | Brand | Whisker | | --- | --- | | Mechanism | Rotating globe | | Cat weight (automatic mode) | 3–30 lb | | Cats per box | Up to 5 | | Kittens & small cats | Under 3 lb: use semi-automatic mode (power off, cycle by hand) until the kitten reaches 3 lb (Whisker). | | Safety sensors | Laser curtain, Weight.

Running costs: with our defaults, consumables for one cat come to about $9.00 a month plus litter.

Confirm the weight range and what's in the box on the Amazon page before buying. We haven’t tested the Litter-Robot 5 ourselves. This review draws on WIRED, whose tester Kat Merck used one with two cats for several months, plus Whisker’s specs and the Amazon listing. The Litter-Robot 5 is Whisker’s newest globe. It keeps the Litter-Robot 4’s large entry, raises the limits to five cats from 3 to 30 lb, and adds WasteID, which tells urine visits from stool visits. Whisker sells the robot for $799. On Amazon it comes only as the Protection & Insights Bundle, which first appeared on October 16, 2026, and we couldn’t capture that bundle’s price. [Check the price](https://www.amazon.com/dp/B0HN8C8TFM?tag=selfcleaninglitterboxguide.com-20) and compare it with Whisker’s. ## Who it’s for (and who should skip it) It’s for large-cat and multi-cat households. A 25 lb-plus Maine Coon, or a home with five cats, is outside what the [Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/) is rated for and inside what the LR5 covers. It also suits owners who want health data on top of hands-off scooping and don’t mind a subscription to get it. Skip it if you have one to three average-size cats. The LR4 does the same core job for about $100 less at Whisker, and the [Litter-Robot EVO](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-evo/) costs $200 less if your cats stay under 19 lb. We set all three side by side in [Litter-Robot 5 vs Litter-Robot 4 vs EVO](https://selfcleaninglitterboxguide.com/posts/litter-robot-5-vs-litter-robot-4-vs-evo/). Skip it as well if you don’t want to pay yearly for features the box advertises. ## How it cleans, and how safe it is The LR5 is a rotating globe that sifts clumps into a sealed drawer, like the LR4. Whisker’s SafeCat system with OmniSense uses multiple lasers plus weight sensors and anti-obstruction detection to spot a cat and stop the cycle. Does the entry stay open through a full cycle? That’s not confirmed. Neither Whisker’s page nor a named review in our sources says so for the LR5, and it isn’t one of WIRED’s picks, which are the boxes WIRED confirms stay open. We’d expect it to behave like the LR4, but we won’t state it as fact. The minimum is 3 lb for automatic mode. Under that, Whisker says to keep it powered off and cycle it by hand. The [cat safety checker](https://selfcleaninglitterboxguide.com/tools/cat-safety-checker/#model=whisker-litter-robot-5) compares your cat’s weight, age and length with the LR5’s limits. For the wider picture, read [are self-cleaning litter boxes safe?](https://selfcleaninglitterboxguide.com/posts/are-self-cleaning-litter-boxes-safe/). ## Living with it ### WasteID and the app WasteID times cycles differently for urine and stool and logs which is which. In WIRED’s testing, WasteID and weight-based cat identification worked only intermittently for the first four months, then improved markedly after firmware updates. Both need Whisker+ (about $80 a year, per WIRED). Without it, you still get a capable cleaning robot. WIRED found the touchscreen finicky and preferred the LR4’s physical buttons. If you want cameras too, the LR5 Pro costs $999 at Whisker and has dual AI cameras, and WIRED says it needs Whisker+ for reliable AI. ### Litter, emptying and odor Whisker recommends clumping clay. The drawer is sealed and uses a carbon filter. In WIRED’s testing it held about 10 days of waste from two cats. See [best litter for self-cleaning litter boxes](https://selfcleaninglitterboxguide.com/posts/best-litter-for-self-cleaning-litter-boxes/) for specific picks. ### Size The LR5 uses the same 22 × 27 in footprint as the LR4 but stands 29.9 in tall and weighs 28.7 lb. Inside, there’s 17.5 in of headroom, about an inch more than the LR4. ## Running costs The LR5 takes the same liners, carbon filters and OdorTrap packs as the LR4. Our cost model uses Whisker’s prices: liners at $25 for 25 (about four per cat per month, our assumption from Whisker’s 8-day emptying figure) and carbon filters at $30 for 6 (one per cat per month). Litter is Dr. Elsey’s Ultra at $22.99 for 40 lb from Chewy, at 10 lb per cat per month. That’s about $14.75 a month for one cat. Over five years, with the robot at $799, we estimate about $1,684 for one cat and about $2,569 for two. Whisker+ is extra: about $80 a year, or roughly $400 over five years, minus the six months included in the Amazon bundle. Change any of these numbers in the [cost calculator](https://selfcleaninglitterboxguide.com/tools/litter-box-cost-calculator/). ## What you’ll need beyond the box - **Litter:** [Dr. Elsey’s Ultra unscented, 40 lb](https://www.amazon.com/dp/B0009X29WK?tag=selfcleaninglitterboxguide.com-20). - **Liners:** [Litter-Robot drawer liners, 25-pack](https://www.amazon.com/dp/B0F3QTK9ZT?tag=selfcleaninglitterboxguide.com-20). - **Cleaning and odor:** Whisker’s [cleaning supply kit](https://www.amazon.com/dp/B09ZCMDXP7?tag=selfcleaninglitterboxguide.com-20) (about $85 in a listing snapshot) includes wipes, 25 liners, spray and six OdorTrap refills. The carbon-filter packs on Amazon are listed for the LR4, so check Whisker’s site for the right LR5 pack before you buy in bulk. - **Ramp and mat:** WIRED recommends adding a ramp (about $75) and a mat (about $50). A [Gorilla Grip 40 × 28 in mat](https://www.amazon.com/dp/B08QNCB6YF?tag=selfcleaninglitterboxguide.com-20) is a cheaper way to cover the floor in front of the entry. On warranty, the robot alone comes with one year of WhiskerCare. The Amazon bundle extends that to three years. Whisker’s holiday banner on November 12, 2026 advertised $150 off select Litter-Robot bundles, so compare our [Black Friday deals roundup](https://selfcleaninglitterboxguide.com/posts/self-cleaning-litter-box-black-friday-deals/) before you pay full price. ## Bottom line The Litter-Robot 5 has the highest cat count of any box we cover and the highest weight limit of any hooded one, on top of Whisker’s laser-and-weight safety system. It’s the right call for very large cats and five-cat homes. WasteID is a genuinely new health tool, but it needs a subscription, and it took months of firmware updates to settle down in WIRED’s testing. If your cats are under 25 lb and you have four or fewer, the LR4 is the better value.

Not to clean. WasteID and cat identification need Whisker+, which WIRED puts at about $80 a year. The Amazon Protection & Insights Bundle includes six months of Whisker+ and a three-year warranty. ### How big a cat can use the Litter-Robot 5? Whisker rates it for cats from 3 to 30 lb and up to five cats. That's the highest cat count of any box we cover, and only the open-top Neakasa M1 (33 lb) has a higher weight limit. The entry is 15.75 × 15.75 in, the same as the Litter-Robot 4, with 17.5 in of interior height, about an inch more than the LR4. ### Can kittens use the Litter-Robot 5? Only in semi-automatic mode until they reach 3 lb. Whisker says to keep the robot powered off and start cycles by hand for lighter kittens, then switch automatic cleaning on once they pass 3 lb. ### Should I buy the Litter-Robot 5 or the Litter-Robot 4? Pick the LR5 if you have a cat over 25 lb, five cats, or you want WasteID's urine-versus-stool tracking and will pay for Whisker+. For most one- to three-cat homes, the Litter-Robot 4 gives the same core cleaning for less, and WIRED preferred its physical buttons to the LR5's touchscreen. ## Sources - [amazon.com](https://www.amazon.com/dp/B0HN8C8TFM?tag=selfcleaninglitterboxguide.com-20) - [litter-robot.com](https://www.litter-robot.com/litter-robot-5.html) - [wired.com](https://www.wired.com/gallery/best-automatic-cat-litter-boxes/) Not sold yet? ## Alternatives to the Litter-Robot 5 ![Whisker Litter-Robot 4](https://selfcleaninglitterboxguide.com/_astro/whisker-litter-robot-4.CZhanV3w_VBSjy.webp) ### [Whisker Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/) 8.7 - Rotating globe - 3–25 lb - Up to 4 cats - Entry stays open Multi-cat homes (up to four cats) and big cats that want the best-supported, most-copied design on the market. $$$$ Premium Price tier: Premium typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0BH6MD3DJ?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/) ![Whisker Litter-Robot EVO](https://selfcleaninglitterboxguide.com/_astro/whisker-litter-robot-evo.qVzR9iO0_14gEYl.webp) ### [Whisker Litter-Robot EVO](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-evo/) 8.6 - Rotating globe - 3–19 lb - Up to 2 cats - Entry stays open One- or two-cat apartments that want Litter-Robot reliability in a footprint close to a regular box. $$$$ Premium Price tier: Premium typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0G6GDC4VN?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-evo/) ![PETKIT Purobot Ultra](https://selfcleaninglitterboxguide.com/_astro/petkit-purobot-ultra.Ca4bd3Io_1eo0Ll.webp) ### [PETKIT Purobot Ultra](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-purobot-ultra/) 7.9 - Tilting drum - 3.3–22 lb Owners who want a camera on every visit and never want to touch a waste bag. $$$$ Flagship Price tier: Flagship typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0DFYJ29XG?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-purobot-ultra/) [Compare all 14 litter boxes →](https://selfcleaninglitterboxguide.com/litter-boxes/) ## Helpful guides [Top picks ### The 8 Best Self-Cleaning Litter Boxes of 2026, Ranked for Safety and Value The best self-cleaning litter boxes of 2026, ranked: Litter-Robot 4, PETKIT PuraMax 2, Purobot Max Pro 2, Neakasa M1 and more, with safety and cost notes.
