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 Leo's Loo Too was a WIRED top pick for a long time, and its radar-plus-weight sensing is reassuring. Its small barrel is both its strength and its weakness: it keeps litter in, but bigger cats find it cramped, and refilling it is fiddly. At about $600 it costs as much as a Litter-Robot EVO, which has a bigger entry. Buy it only if floor space and scatter matter more than headroom. ### What we like - Radar plus four weight sensors and an anti-pinch sensor - Smallest opening here, which Tom's Guide found contained scatter best - About 30 dB motor (maker claim) and UV-C odor control - Works with Alexa and Google Assistant ### Watch out for - Cramped: WIRED's 12-lb cat found the barrel tight - Hard to pour new litter through the small opening (WIRED, Tom's Guide) - Tom's Guide's cats used it about a third as often as the Litter-Robot 4 - Expensive for its size, and warranty terms differ between listings ## Score breakdown Cat safety 8.4 Cleaning & odor 8 Ease & reliability 7.4 Value 6.8 Tilting drum · cats 1–20 lb · Weight, Radar, Anti-pinch ## Leo's Loo Too specs | Brand | Casa Leo | | --- | --- | | Mechanism | Tilting drum | | Cat weight (automatic mode) | 1–20 lb.

Running costs: with our defaults, consumables for one cat come to about $4.30 a month plus litter. See the full breakdown in the [cost calculator](https://selfcleaninglitterboxguide.com/tools/litter-box-cost-calculator/). Specs are compiled from manufacturer pages, Amazon listings and independent reviews and can change between production runs. Confirm the weight range and what's in the box on the Amazon page before buying. We haven’t tested Leo’s Loo Too ourselves. This review draws on WIRED, which named it a top pick for a long time, and on Tom’s Guide, which tested it against the Litter-Robot 4, Neakasa M1 and ELS PET Orbitie. Specs come from Casa Leo (also sold as Smarty Pear) and the Amazon listing. Leo’s Loo Too is a compact front-entry drum with radar, four weight sensors, an anti-pinch sensor and UV-C odor control. Its small barrel is both its strength and its weakness. Tom’s Guide found it contained litter scatter best of the four boxes it tested, but WIRED’s 12-lb cat found it tight. It costs about $600. Tom’s Guide’s April 2025 price box showed $599 at Amazon, and WIRED lists it at $600. [Check the price](https://www.amazon.com/dp/B09LL9S99B?tag=selfcleaninglitterboxguide.com-20) before you buy. ## Who it’s for (and who should skip it) It’s for small apartments with small or medium cats, where litter on the floor is the main complaint. It also has the lowest detection threshold we’ve found, and it works with Alexa and Google Assistant. Skip it if your cat is over about 12 lb or picky about space. WIRED’s 12-lb cat found the barrel tight, and Tom’s Guide’s cats used it about a third as often as the [Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/). Skip it on value, too: at about $600 it costs as much as the [Litter-Robot EVO](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-evo/), which has a bigger entry and Whisker’s support behind it. If scatter is your main concern and you can spend less, the [PETKIT PuraMax 2](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-puramax-2/) is enclosed too, for about $390. ## How it cleans, and how safe it is According to Casa Leo and WIRED, four weight sensors, an anti-pinch sensor and radar that detects anyone near the box before a cycle work together. WIRED says it needs only 1 lb on its sensors to detect a cat. That’s a meaningful safety margin for small cats, and the radar adds a check before the drum moves. Whether the entrance stays open through the whole cycle is not confirmed. Neither Casa Leo nor a named review in our sources says so. The anti-pinch sensor addresses some of the same risk, but it’s not the same as a confirmed open entry. Casa Leo rates the drum from 1 lb. Even so, keep automatic cleaning off and supervise small kittens. A low threshold helps, but no sensor makes an unsupervised young kitten risk-free. Check your cat’s weight, age and length with the [cat safety checker](https://selfcleaninglitterboxguide.com/tools/cat-safety-checker/#model=casa-leo-leos-loo-too), and see [best self-cleaning litter box for kittens](https://selfcleaninglitterboxguide.com/posts/best-self-cleaning-litter-box-for-kittens/). ## Living with it ### Fit and cat acceptance Casa Leo doesn’t publish the entry size. Tom’s Guide calls it the smallest opening of the four boxes it tested, and WIRED found the barrel cramped for a 12-lb cat. In Tom’s Guide’s week-long count, the Litter-Robot 4 got almost three times as many visits. If your cat hesitates, follow our [transition guide](https://selfcleaninglitterboxguide.com/posts/how-to-transition-cat-to-automatic-litter-box/) and keep the old box out longer. ### Litter and refilling It uses clumping litter. Both WIRED and Tom’s Guide found it hard to pour new litter through the small opening, so expect refills to take some care. ### Emptying and odor The 9.5 L drawer is sealed, and a UV-C light adds odor control. WIRED’s tester got a drawer-full alert about once a week. Consumables are Casa Leo liners and charcoal air-freshener bags, or generic liners. For more on keeping smells down, see [self-cleaning litter box odor fixes](https://selfcleaninglitterboxguide.com/posts/self-cleaning-litter-box-odor-fixes/). ### Noise and size Casa Leo claims about 30 dB for the motor. The Amazon listing title gives about 24 × 22 × 27.6 in. Some listings still show the older Smarty Pear brand name, so don’t be thrown if the seller name differs. ## Running costs Leo’s Loo Too takes Casa Leo liners or generic ones. Our cost model uses Whisker’s $1-per-liner price as a stand-in at about one bag per cat per week, plus Dr. Elsey’s Ultra at $22.99 for 40 lb from Chewy, at 10 lb per cat per month. That’s about $10 a month, or roughly $121 a year, for one cat. Over five years, with the box at $599, we estimate about $1,202 for one cat and about $1,805 for two. Running costs are moderate. The purchase price is what makes this box expensive. Try your own 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:** Casa Leo’s own liners or generic drawstring bags. We don’t list a specific liner because we couldn’t confirm a fit. - **Mat:** a [Gorilla Grip 35 × 23 in mat](https://www.amazon.com/dp/B07HKN7HMP?tag=selfcleaninglitterboxguide.com-20). The enclosed barrel contains most scatter, so a standard-size mat should do. ## Bottom line Leo’s Loo Too has reassuring sensing: radar, four weight sensors, anti-pinch protection and a 1 lb detection threshold. Tom’s Guide found it best at keeping litter in. The trade-offs are a cramped barrel that bigger cats avoid, fiddly refilling, and a price that matches roomier boxes. Buy it only if floor space and scatter matter more than headroom. For most homes, the EVO or the PuraMax 2 is the better buy.

Not really. Casa Leo rates the drum for cats up to 20 lb, but WIRED's 12-lb cat found the barrel tight, and Tom's Guide called its opening the smallest of the four boxes it tested. For big cats, the Litter-Robot 4 or the open-top Neakasa M1 has far more room. ### Can kittens use Leo's Loo Too? Casa Leo rates it from 1 lb, and WIRED notes it needs just 1 lb on its sensors to detect a cat. That's the lowest threshold we've found, but no sensor makes an unsupervised young kitten risk-free. Keep automatic cleaning off and supervise small kittens. ### How loud is Leo's Loo Too? Casa Leo claims about 30 dB for the motor, among the quietest figures for the boxes we cover. That's a maker claim, not a measured result. ### What warranty does Leo's Loo Too have? Casa Leo gives one year. One Amazon listing advertises three years, and others say one year, so check the terms on the specific listing before you buy. ## Sources - [amazon.com](https://www.amazon.com/dp/B09LL9S99B?tag=selfcleaninglitterboxguide.com-20) - [smartypear.com](https://www.smartypear.com/product/leos-loo-too/) - [wired.com](https://www.wired.com/gallery/best-automatic-cat-litter-boxes/) - [tomsguide.com](https://www.tomsguide.com/home/smart-home/my-cats-have-tested-these-robotic-litter-boxes-for-months-heres-the-one-they-use-the-most) Not sold yet? ## Alternatives to the Leo's Loo Too ![PETKIT Purobot Max Pro 2](https://selfcleaninglitterboxguide.com/_astro/petkit-purobot-max-pro-2.tJpodhLt_opqwl.webp) ### [PETKIT Purobot Max Pro 2](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-purobot-max-pro-2/) 8.6 - Tilting drum - 3.3–22 lb - Entry stays open Large cats and camera fans: WIRED's 17-lb tester used it easily. $$$$ Mid-range Price tier: Mid-range typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0DFYLFFG1?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-purobot-max-pro-2/) ![PETKIT Purobot Ultra](https://selfcleaninglitterboxguide.com/_astro/petkit-purobot-ultra.Ca4bd3Io_1eo0Ll.webp) ### [PETKIT Purobot Ultra](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-purobot-ultra/) 7.9 - Tilting drum - 3.3–22 lb Owners who want a camera on every visit and never want to touch a waste bag. $$$$ Flagship Price tier: Flagship typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0DFYJ29XG?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-purobot-ultra/) ### [PETKIT PuraMax 2](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-puramax-2/) 8.5 - Tilting drum - 3.3–22 lb - Entry stays open Most one- to three-cat homes with average-size cats: the best value among the well-reviewed boxes. $$$$ Mid-range Price tier: Mid-range typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0DFYF2D7D?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-puramax-2/) [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.
