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 SmartSpin is PetSafe's answer to the PuraMax 2. It's a spherical box on legs that sifts into a sealed drawer and logs visits in an app. WIRED found it worked surprisingly well. It relies on a weight detector alone, though, and it sits 12 in off the floor. At its usual price the PuraMax 2 gives you more sensors for the same money. ### What we like - Rated for cats up to 25 lb (PetSafe) - WIRED: easy to build and works surprisingly well - App logs each visit's time, weight and duration - Smooth interior with no grooves, simple to wipe down ### Watch out for - Weight detection only; no infrared or laser curtain - The 12 in height is a climb for senior cats - WIRED says it feels "kinda cheap" - 2.4 GHz Wi-Fi only ## Score breakdown Cat safety 7.8 Cleaning & odor 8 Ease & reliability 8.2 Value 7.6 Tilting drum · cats 2.5–25 lb · Weight ## ScoopFree SmartSpin specs | Brand | PetSafe | | --- | --- | | Mechanism | Tilting drum | | Cat weight (automatic mode) | 2.5–25 lb.

Confirm the weight range and what's in the box on the Amazon page before buying. We haven’t tested the PetSafe ScoopFree SmartSpin ourselves. This review draws on WIRED, which tested it among more than 30 automatic boxes, plus PetSafe’s specs and the Amazon listing. The SmartSpin is PetSafe’s answer to the PETKIT PuraMax 2: a spherical box on legs that turns to sift clumps into a sealed drawer and logs visits in an app. Unlike PetSafe’s crystal boxes, it takes ordinary clumping litter. PetSafe lists it at $399.99, and WIRED lists it at $340. [Check the price](https://www.amazon.com/dp/B0D4GHS7V6?tag=selfcleaninglitterboxguide.com-20), since the gap between those two figures is wide. ## Who it’s for (and who should skip it) It’s for owners who want a big-brand box with app tracking under $400 and who’d rather use regular clumping litter than buy proprietary trays. It’s rated for cats up to 25 lb, and WIRED found it easy to build and said it works surprisingly well. Skip it if you want more than one kind of sensor. The SmartSpin relies on weight detection alone. At a similar price, the [PETKIT PuraMax 2](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-puramax-2/) combines proximity and weight sensors, and PETKIT says its entrance stays open during rotation. Skip it too if you have a senior cat, given the 12 in height. If build quality matters, note WIRED’s comment that it feels “kinda cheap”. ## How it cleans, and how safe it is WIRED says a weight detector starts the cycle a few minutes after the cat leaves. That’s the only detection method: there’s no infrared or laser curtain like those on the [Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/) or the PETKIT boxes. Weight-only sensing works as long as the cat is heavy enough to register, which is why the kitten rule matters. Whether the entry stays open through the whole cycle is not confirmed. Neither PetSafe nor a named review in our sources says so either way. Watch the first few cycles yourself. The Amazon listing says to keep the box unplugged or auto-clean off until a kitten is at least 2.5 lb and 6 months old. Put your cat’s numbers into the [cat safety checker](https://selfcleaninglitterboxguide.com/tools/cat-safety-checker/#model=petsafe-scoopfree-smartspin), and read [are self-cleaning litter boxes safe?](https://selfcleaninglitterboxguide.com/posts/are-self-cleaning-litter-boxes-safe/) to see how weight-only boxes compare with multi-sensor designs. ## Living with it ### Litter PetSafe says any litter works and recommends premium clumping litter. WIRED found it worked surprisingly well. The interior is smooth with no grooves, which makes it simple to wipe down between litter changes. See [best litter for self-cleaning litter boxes](https://selfcleaninglitterboxguide.com/posts/best-litter-for-self-cleaning-litter-boxes/). ### Emptying and odor The 6 L drawer holds up to two weeks of waste for one cat, according to PetSafe. The Amazon listing says to empty it weekly with two or more cats. The drawer is sealed and has a clip-in deodorizer, and each deodorizer lasts about 15 days. ### App The app logs each visit’s time, weight and duration. It connects over 2.4 GHz Wi-Fi only, so check that your router broadcasts a 2.4 GHz network. ### Height The box sits 12 in from the ground, according to PetSafe. That’s a climb for older cats or cats with mobility problems, so turn on the mobility option in the [safety checker](https://selfcleaninglitterboxguide.com/tools/cat-safety-checker/#model=petsafe-scoopfree-smartspin&mobility=1) if that’s your cat. ## Running costs The SmartSpin’s consumables are cheap. Liners cost $17.99 for 25 at list price on Amazon (a snapshot showed $13.49). Our cost model assumes about 2.2 liners per cat per month, from PetSafe’s two-week drawer figure, which works out to about $1.58 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 $7.33 a month, or roughly $88 a year, for one cat. Over five years, with the box at $340, we estimate about $780 for one cat and about $1,220 for two. That’s the lowest five-year total among the boxes we’ve modeled. Deodorizers aren’t included, because we couldn’t confirm their price. Adjust the inputs 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:** [SmartSpin waste bin liners, 25 count](https://www.amazon.com/dp/B0D1VYP9P3?tag=selfcleaninglitterboxguide.com-20), $17.99 list. - **Deodorizers:** [SmartSpin deodorizers, 2-pack](https://www.amazon.com/dp/B0D5MKRSL7?tag=selfcleaninglitterboxguide.com-20). Each lasts about 15 days. - **Mat:** a [Gorilla Grip 35 × 23 in mat](https://www.amazon.com/dp/B07HKN7HMP?tag=selfcleaninglitterboxguide.com-20). The [SmartSpin Bundle](https://www.amazon.com/dp/B0DZK3JB6F?tag=selfcleaninglitterboxguide.com-20) in black adds a litter mat, 50 liners and four deodorizers if you’d rather buy everything at once. The warranty is a one-year limited warranty. ## Bottom line The SmartSpin is a solid, cheap-to-run clumping-litter box from a big brand. WIRED found it worked surprisingly well, the app logs visits and weight, and it has the lowest five-year cost we’ve modeled. The trade-offs are weight-only sensing, a 12 in step-up, a build WIRED calls cheap-feeling, and an entry we can’t confirm stays open during cycling. At its usual price, the PuraMax 2 gives you more sensors for about the same money.

The Amazon listing says to keep it unplugged, or auto-clean off, until a kitten weighs at least 2.5 lb and is 6 months old. Because the SmartSpin detects cats by weight alone, follow both conditions, not just the weight. ### How many cats can share a SmartSpin? PetSafe calls it ideal for multi-cat homes but gives no number. The listing says to expect to empty the drawer up to every two weeks with one cat and weekly with two or more. Vets still advise one box per cat plus one, so keep a second box if you have several cats. ### What litter works in the SmartSpin? PetSafe says any litter works and recommends premium clumping litter. Unlike PetSafe's ScoopFree Crystal boxes, it doesn't need proprietary trays. ### Is the SmartSpin good for senior cats? Think twice. PetSafe says the box sits 12 in from the ground, which is a climb for stiff or arthritic cats. Compare heights before you buy: the ScoopFree Classic, for example, is 7.1 in tall overall. ## Sources - [amazon.com](https://www.amazon.com/dp/B0D4GHS7V6?tag=selfcleaninglitterboxguide.com-20) - [petsafe.com](https://www.petsafe.com/product/scoopfree-smartspin-self-cleaning-litter-box/) - [wired.com](https://www.wired.com/gallery/best-automatic-cat-litter-boxes/) Not sold yet? ## Alternatives to the ScoopFree SmartSpin ### [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. $$$$ Mid-range Price tier: Mid-range typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0DFYF2D7D?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-puramax-2/) ![ELS PET Orbitie Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/_astro/els-pet-orbitie.Cbn-Hh0r_1s2IDq.webp) ### [ELS PET Orbitie Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/litter-boxes/els-pet-orbitie/) 7.2 - Tilting drum - up to 21 lb Budget buyers who want a hooded globe with a generous entry and accept some fiddling. $$$$ Budget Price tier: Budget typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0GL8MSKZX?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/els-pet-orbitie/) ![PETKIT Purobot Max Pro 2](https://selfcleaninglitterboxguide.com/_astro/petkit-purobot-max-pro-2.tJpodhLt_opqwl.webp) ### [PETKIT Purobot Max Pro 2](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-purobot-max-pro-2/) 8.6 - Tilting drum - 3.3–22 lb - Entry stays open Large cats and camera fans: WIRED's 17-lb tester used it easily. $$$$ 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/) [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.
