Overview
The PetSafe ScoopFree Crystal Smart is the simplest system in our smart litter box guide. Instead of a rotating globe, it uses a rake that sweeps waste into a covered compartment at one end of a disposable tray filled with PetSafe crystal litter. When the tray is used up, you lift out the whole thing, throw it away and drop in a new one. No scooping and no bagging. The unit plugs into the wall and shows its status on a small LCD screen.
The version we link (ASIN B087C6XZCL) is the uncovered model. PetSafe also sells a hooded Front-Entry version under a different listing.
Key features
- Uncovered design: 27.6 x 19.1 x 6.2 in, low enough to fit under many counters
- Automatic rake moves waste into a covered section of the tray
- Uses PetSafe ScoopFree crystal litter trays only; PetSafe suggests a new tray about monthly
- Wi-Fi and My PetSafe app: activity logs, a health counter and tray-change alerts
- LCD display on the unit; plug-in power
- PetSafe positions it for single- or multi-cat use
Who it suits (and who should skip it)
It suits owners who want the least contact with litter of any box here. Crystal litter controls odour well and tracks less than clay, and the tray swap takes a minute. The low profile also helps in tight spaces where a tall globe would not fit.
Skip it if your cat dislikes the feel of crystal litter, or if you want weight-based cat identification. PetSafe’s page describes visit logs and a health counter but does not document a weight scale, so you get less data than with the Whisker or PETKIT boxes. We could not find PetSafe’s minimum kitten age or weight on the pages we read; check the manual before using it with a young kitten and supervise early cycles. Also check that the My PetSafe app is available in your country’s app store if you are in Canada, as we could not confirm Canadian app support.
Costs to know about
There is no app subscription, but this box locks you into PetSafe’s proprietary crystal trays. You will need roughly one per month for one cat, and more often with several cats, which makes it the highest consumable cost in this category over time. Keep a spare tray in the cupboard so a tray-change alert never catches you short, especially in multi-cat homes. PetSafe offers a 45-day satisfaction guarantee; we could not confirm the warranty length.
How it compares
The Neakasa M1 Plus Lite is also open but uses ordinary clumping litter and standard bags, so it is cheaper to run over a year or two. The PETKIT PuraMax 2 adds per-cat weight tracking and an enclosed drum for better odour control. If a hesitant cat starts going elsewhere, our guide to removing pet stains naturally helps.

Frequently asked questions
How often do you change the ScoopFree tray?
PetSafe suggests about once a month for one cat. With more cats, the crystals saturate faster and you will change trays more often. The My PetSafe app sends a tray-change alert, and the health counter shows how often the box is being used.
Can I use regular litter in the PetSafe ScoopFree Crystal Smart?
No. The system is designed around PetSafe's disposable crystal litter trays, and the rake and covered waste compartment depend on that tray. Using clay or other litter is not supported. If you want to choose your own litter, look at a clumping-litter box such as the Neakasa M1 Plus Lite or PETKIT PuraMax 2.
Is the ScoopFree safe for kittens?
We could not find PetSafe's minimum kitten age or weight on the brand pages we read. Check the manual in the box before using automatic mode with a young kitten, keep the first cycles supervised, and use a standard tray if your kitten seems frightened by the rake.
Is this the covered or uncovered ScoopFree?
The listing we link, ASIN B087C6XZCL, is the uncovered Crystal Smart. PetSafe also sells a Front-Entry hooded version that stands 15.6 in tall under a different listing. Both use the same crystal trays and app, so choose based on whether your cat prefers a hood.
