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 Crystal Smart is the low-anxiety option. No globe or drum turns, so there's nothing to trap a cat, and the app nudges you when the tray is due. The catch is cost. Each disposable tray runs about $24.50 and lasts about a month for one cat, so over five years the trays cost several times the box. It makes sense for one cat that already likes crystal litter. ### What we like - Nothing encloses the cat: a rake moves across an open tray - App tracks visits and reminds you to swap the tray - Low-dust crystals track less than clay (PetSafe claim) - No litter bags to buy or pour ### Watch out for - Needs PetSafe trays at about $24.50 each, roughly one per cat per month - Crystal litter only; cats that dislike crystals won't use it - Designed for one or two cats - Low tray walls on the uncovered version ## Score breakdown Cat safety 8.8 Cleaning & odor 7.4 Ease & reliability 8.4 Value 6.8 Rake + crystal tray · cats not published · Infrared ## ScoopFree Crystal Smart specs | Brand | PetSafe | | --- | --- | | Mechanism | Rake + crystal tray | | Cat weight (automatic mode) | not published | | Minimum age | 6 months (maker guidance) | | Cats per box | Up to 2.

Running costs: with our defaults, consumables for one cat come to about $24.50 a month including the litter. Trays include the litter, so there's no separate litter cost.

Prices, where shown, are dated snapshots, not live prices. | Option | What's different | Price | | --- | --- | --- | | Crystal Smart, front-entry (hooded) | Our pick | [Check price](https://www.amazon.com/dp/B087C7K4CP?tag=selfcleaninglitterboxguide.com-20) | | Crystal Smart, uncovered | Same box without the hood | [Check price](https://www.amazon.com/dp/B087C6XZCL?tag=selfcleaninglitterboxguide.com-20) | 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 the PetSafe ScoopFree Crystal Smart ourselves, and none of the outlets whose testing we rely on has published results for it. This review draws on PetSafe’s product page and tray pricing, the Amazon listing, and Chewy’s listing and customer answers. The Crystal Smart is a different kind of self-cleaning box. Instead of a turning globe or drum, a rake sweeps across a disposable tray of crystal litter. An app counts visits and tells you when the tray is due. PetSafe lists it at $269.99, and dated snapshots showed $185.58 at PetSmart and $299.99 at Chewy. [Check the price](https://www.amazon.com/dp/B087C7K4CP?tag=selfcleaninglitterboxguide.com-20), because it moves around a lot. ## Who it’s for (and who should skip it) It’s for one-cat homes where the cat already likes crystal litter and the owner wants app reminders, no moving enclosure and no litter to pour. It’s also the low-anxiety option for owners worried about a cat getting caught in a rotating box. Skip it if your cat prefers soft clumping litter. Vets at the AAFP and ISFM note that most cats prefer soft, unscented clumping litter. Crystals aren’t that, and a cat that won’t use the tray makes the whole box pointless. Skip it too if you have two cats and a budget, because tray costs double. The [ScoopFree SmartSpin](https://selfcleaninglitterboxguide.com/litter-boxes/petsafe-scoopfree-smartspin/) is PetSafe’s clumping-litter alternative with much lower running costs. ## How it cleans, and how safe it is PetSafe and the Amazon listing say safety sensors keep the rake still while a cat is present, and the rake starts about 20 minutes after the cat leaves. Nothing encloses the cat. A rake moves across an open tray, and the hooded front-entry version has no door. That design removes the biggest risk with self-cleaning boxes, a cat caught in a closing chamber. It doesn’t mean unsupervised kittens are fine. PetSafe says to keep ScoopFree boxes unplugged and scoop by hand until a kitten is 6 months old. PetSafe doesn’t publish a weight limit for the Smart. Its Canadian FAQ for the Crystal Classic says ScoopFree boxes are designed for cats up to 15 lb, so a large cat may find it tight. Run your cat through the [cat safety checker](https://selfcleaninglitterboxguide.com/tools/cat-safety-checker/#model=petsafe-scoopfree-crystal-smart). ## Living with it ### The trays Everything revolves around the trays. Each comes pre-filled with crystal litter, absorbs urine and dries out stool. When it’s spent, you throw the whole tray away. There’s no litter to pour and no bags to buy. PetSafe also claims the crystals are low-dust and track less than clay. It also claims five times better odor control, though that’s PetSafe’s figure, not a test result. ### The app The My PetSafe app counts visits as a basic health tracker and reminds you to swap the tray. ### Size and versions The hooded front-entry version measures 27.6 × 19.1 × 15.6 in. There’s also an [uncovered version](https://www.amazon.com/dp/B087C6XZCL?tag=selfcleaninglitterboxguide.com-20) at 6.2 in tall, but its tray walls are low. ## Running costs The trays are the cost to plan for. PetSafe sells a 3-pack for $73.49, about $24.50 per tray, and the trays include the litter, so you don’t buy any separately. | Cats | Trays per month | Monthly | Yearly | 5 years with the box at $186 | | --- | --- | --- | --- | --- | | One | about 1 | about $24.50 | about $294 | about $1,656 | | Two | about 2 | about $49 | about $588 | about $3,126 | Over five years, the trays cost several times what the box does. A clumping-litter box like the SmartSpin comes out far cheaper to run, at about $88 a year for one cat in our model. Compare models side by side in the [cost calculator](https://selfcleaninglitterboxguide.com/tools/litter-box-cost-calculator/), and read [PetSafe ScoopFree vs Litter-Robot](https://selfcleaninglitterboxguide.com/posts/petsafe-scoopfree-vs-litter-robot/) for the longer view. ## What you’ll need beyond the box - **Trays:** [ScoopFree crystal tray refills, premium blue, 3-pack](https://www.amazon.com/dp/B000FEF10A?tag=selfcleaninglitterboxguide.com-20) (about $73.49 at PetSafe). Stock up during sales. - **Scented alternative:** [lavender trays, 3-pack](https://www.amazon.com/dp/B07GBHK2TZ?tag=selfcleaninglitterboxguide.com-20). Many cats dislike scented litter, so try unscented first. - **Mat:** a [Gorilla Grip 35 × 23 in mat](https://www.amazon.com/dp/B07HKN7HMP?tag=selfcleaninglitterboxguide.com-20) for any crystals that get tracked out. ## Bottom line The Crystal Smart is the most reassuring design for a nervous owner. No globe or drum turns, the rake waits about 20 minutes after each visit, and the app tells you when to change the tray. The catch is cost: about $24.50 a tray, roughly one per cat per month, for as long as you own it. It makes sense for one cat under about 15 lb that already likes crystal litter. Otherwise, a clumping-litter box will be cheaper to live with. If you don’t need the app, the [ScoopFree Classic](https://selfcleaninglitterboxguide.com/litter-boxes/petsafe-scoopfree-crystal-classic/) uses the same trays for about $100.

No. It works only with PetSafe's disposable ScoopFree crystal trays, which come pre-filled. If your cat dislikes crystal litter, this box won't work for you; look at a clumping-litter box such as the PETKIT PuraMax 2 instead. ### How long does one ScoopFree tray last? PetSafe says about a month for one cat. A Chewy answer gives 20–30 days for one cat and 10–15 days for two. At PetSafe's price of $73.49 for three, each tray costs about $24.50. ### Is the Crystal Smart safe for kittens? PetSafe's ScoopFree guidance is to keep the box unplugged and scoop by hand until a kitten is 6 months old. No globe or drum turns, so there's nothing to enclose a cat, but the rake still moves. ### Can two cats share the Crystal Smart? Chewy's listing says it's designed for one or two cats. With two, expect a new tray roughly every two weeks, which doubles the running cost to about $49 a month at PetSafe's tray price. ## Sources - [amazon.com](https://www.amazon.com/dp/B087C7K4CP?tag=selfcleaninglitterboxguide.com-20) - [petsafe.com](https://www.petsafe.com/product/smart-self-cleaning-litter-box-scoopfree/) - [petsafe.com](https://www.petsafe.com/shop/cat/litter-boxes-and-litter/litter/) - [chewy.com](https://www.chewy.com/petsafe-smart-wifi-enabled-covered/dp/261382) Not sold yet? ## Alternatives to the ScoopFree Crystal Smart ![PetSafe ScoopFree Crystal Classic Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/_astro/petsafe-scoopfree-crystal-classic.CJ4bZlM__Zdvfgw.webp) ### [PetSafe ScoopFree Crystal Classic Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/litter-boxes/petsafe-scoopfree-crystal-classic/) 7.8 - Rake + crystal tray - up to 15 lb - Up to 2 cats - Entry stays open The cheapest way to stop scooping, for one small-to-medium cat that accepts crystal litter. $$$$ Budget Price tier: Budget typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0CFRY7VYN?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/petsafe-scoopfree-crystal-classic/) ### [Lesure Open-Top Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/litter-boxes/lesure-open-top/) 8.0 - Open-top - 3.3–18 lb - Entry stays open A first automatic box on a budget, for cats who like an open pan. $$$$ Budget Price tier: Budget typical street price; check Amazon for today's [Check price on Amazon](https://www.amazon.com/dp/B0GJ5BMVFS?tag=selfcleaninglitterboxguide.com-20)[Read the full review](https://selfcleaninglitterboxguide.com/litter-boxes/lesure-open-top/) ![ELS PET Orbitie Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/_astro/els-pet-orbitie.Cbn-Hh0r_1s2IDq.webp) ### [ELS PET Orbitie Self-Cleaning Litter Box](https://selfcleaninglitterboxguide.com/litter-boxes/els-pet-orbitie/) 7.2 - Tilting drum - up to 21 lb Budget buyers who want a hooded globe with a generous entry and accept some fiddling. $$$$ 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/) [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.
