Searching for the best ScoopFree litter box gets confusing fast: PetSafe now sells several boxes under the ScoopFree name, and they don't all work the same way. Some use disposable crystal trays, one uses your regular clumping litter, and the newest one rotates like a Litter-Robot. Here's how they differ and which one fits your cat.
Every ScoopFree worth considering
1ScoopFree Crystal Pro (open-top): the best ScoopFree for most cats
Best for: one cat, renters and anyone who wants the simplest setup.
Skip it if: your cat refuses crystal litter, or you'd rather not buy refill trays for as long as you own it.
Why it's on the list
This is the classic ScoopFree most people mean. A few minutes after your cat leaves, a rake sweeps solid waste into a covered compartment at the end of a disposable tray, and crystal litter absorbs urine and dries out solids. Every few weeks you lift out the whole tray, close its lid and drop in a fresh one. There's no litter to pour and almost no dust.
2ScoopFree Crystal Pro front-entry: the same box with a hood
Best for: cats that like a hooded box, and homes where the box sits in a closet or laundry room.
Skip it if: your cat won't use covered boxes.
Why it's on the list
Same rake-and-tray system as the open-top Crystal Pro, but covered, with a front entry for privacy and less litter kicked out. PetSafe says the roomy interior suits large cats, and a health counter logs how often your cat visits, which can flag a change in routine early. PetSafe says a single-cat home can go up to a month on one tray; multi-cat homes change trays more often.
3ScoopFree Crystal Classic: the lowest-cost way in
Best for: a single cat and a first try at automatic boxes.
Skip it if: you want visit tracking or have more than one cat.
Why it's on the list
The Classic is the budget ScoopFree: the same automatic rake and leak-resistant, plastic-lined crystal trays, without the health counter. If you just want to stop scooping and keep the up-front cost down, start here.
4ScoopFree Clumping: for cats that only accept clumping litter
Best for: cats that are fussy about litter, and owners who don't want ongoing tray costs.
Skip it if: you want the most proven model; owner ratings on the listing are mixed, so read recent reviews first.
Why it's on the list
The big catch with most ScoopFree boxes is crystal litter, and plenty of cats won't switch. The Clumping model fixes that: it rakes your cat's usual clumping litter and locks clumps in a waste bin, so there are no disposable trays to buy. PetSafe says to empty the bin about once a week and refresh the litter now and then, and it lists it for single and multi-cat homes.
5ScoopFree SmartSpin: PetSafe's app-connected rotating box
Best for: owners who want app tracking and a rotating box from the ScoopFree brand.
Skip it if: you're comparing it directly with the Litter-Robot 4, which has a longer track record; see our Litter-Robot vs ScoopFree comparison.
Why it's on the list
SmartSpin is PetSafe's answer to the Litter-Robot. Instead of a rake, it rotates to sift clumps into a sealed waste drawer, with up to 2 weeks of hands-free cleaning per PetSafe. The Pet Companion app shows weight updates and visit history (2.4 GHz Wi-Fi), it works with clumping or non-clumping litter, and the entry sits about 12 inches off the floor for cats up to 25 lb.
6ScoopFree refill trays: price these before you buy a crystal model
Every crystal ScoopFree (Pro and Classic) runs on these disposable crystal trays, so they're the real running cost. Multi-packs bring the per-tray cost down. Keep one spare in the closet so a full tray never has to wait for a delivery.
Why it's on the list
The Clumping and SmartSpin models don't use these trays.
7Not set on ScoopFree? The Litter-Robot 4 for multi-cat homes
If you have two to four cats, a rake-and-tray box fills up fast. The Litter-Robot 4 uses normal clumping litter, sifts it in a rotating globe and drops clumps into a lined drawer, and Whisker says it suits up to 4 cats. It costs much more up front but has no tray refills.
Why it's on the list
For the full breakdown, read self-cleaning litter boxes for multiple cats.
Why this one matters at Fur & Nest: Amir Dabiri, who runs Fur & Nest, has three cats (Mittens, Smalls and Binks). Litter is a daily topic in a three-cat house, and the first question with ScoopFree is always the same: will your cat accept crystal litter, and how many cats does the box have to handle?
We compare these using what PetSafe says about each model and what the Amazon listings show. For every type of automatic box, see our full self-cleaning litter box guide.
ScoopFree models at a glance
- Crystal Pro (open-top): rake plus disposable crystal tray. Best all-round pick for one cat.
- Crystal Pro (front-entry): same system with a hood and a visit counter.

How to choose
- Will your cat use crystal litter? If not, skip the Crystal models and look at Clumping or SmartSpin.
- How many cats? Tray models suit one cat best. With two or more, lean toward Clumping, SmartSpin or a Litter-Robot.
- Running cost: crystal models need refill trays for as long as you use them. Price a few months of trays before deciding.
- Space: measure your spot, and leave room to slide trays or drawers out.
Tips for switching to a ScoopFree
- Set the new box next to the old one for a few days before removing the old one.
- If you're moving to crystal litter, sprinkle a little of the old litter on top at first.
- Put a trapping mat in front of the box to catch stray crystals.
Frequently asked questions
Which ScoopFree is best?
For most single-cat homes, the open-top ScoopFree Crystal Pro. Choose the front-entry Crystal Pro if your cat likes a hood, the Crystal Classic for the lowest starting cost, the Clumping model if your cat refuses crystal litter, and SmartSpin if you want a rotating box with an app.
Can you use regular litter in a ScoopFree?
Not in the Crystal Pro or Crystal Classic; they're built around PetSafe's disposable crystal trays. The ScoopFree Clumping model works with clumping litter, and SmartSpin takes clumping or non-clumping litter.
How long does a ScoopFree tray last?
PetSafe says up to about a month for one cat with the Crystal Pro. With more cats, plan to change trays more often.
Is ScoopFree good for multiple cats?
The tray models work best with one cat. For two or more, look at the ScoopFree Clumping model or a larger box like the Litter-Robot 4.
ScoopFree or Litter-Robot?
ScoopFree costs far less to buy but needs refill trays (crystal models). The Litter-Robot 4 costs much more but uses ordinary clumping litter and suits up to 4 cats. Our Litter-Robot vs ScoopFree comparison covers it in detail.
