Side by side
PetSafe Crystal Pro Legacy vs SmartSpin Compared: SmartSpin needs acceptance of a globe, whereas Legacy keeps an open crystal tray
Quick verdict
The uncovered Crystal Pro Legacy is for a cat that accepts crystals and likes an open box. SmartSpin is for compatible clumping litter, remote weight records and an enclosed globe that your cat is willing to enter.
Before you buy
Why, and what it costs you
Your cat's litter preference can undo the obvious upgrade
A cat that already uses crystals may adjust more easily to Crystal Pro’s uncovered tray. SmartSpin recommends premium clumping litter and asks the cat to enter a globe, so it is the pick only if the cat accepts both changes. If keeping the open crystal setup matters more to you than connected features, go with Crystal Pro.
Where this comes from
Two separate acceptance conditions sit behind the buying decision, texture and enclosure.
The catch

A slower introduction may be needed for an enclosed entry.

Differences you will notice
Your cat's litter preference can undo the obvious upgrade
A cat that already uses crystals may adjust more easily to Crystal Pro’s uncovered tray.

How we worked this out
Two separate acceptance conditions sit behind the buying decision, texture and enclosure.
How often you empty depends on the waste system
In Crystal Pro the tray absorbs urine while a rake carries solids off. SmartSpin drops clumps into a six-liter drawer. If you would rather change a liner, SmartSpin is the pick, and if swapping or maintaining a crystal tray suits you, Crystal Pro is. Do not choose either on a promise of fixed weeks between cleanings when several cats use it.
How we worked this out
You can't convert a drawer volume into a service interval that compares with the crystal tray's.
Remote weight records set SmartSpin apart from a visit counter
The local counter on Crystal Pro shows use at the box itself, while SmartSpin sends weight and visit information through the Pet Companion app. SmartSpin is the pick if checking patterns remotely would change how you supervise a multi-cat home, and Crystal Pro is the pick if looking in person is enough. Neither is a medical diagnostic device.
How we worked this out
In the source, recorded weight and remote access are set apart from a local use count.

Spec by spec
Where they really differ
| Spec | PetSafe ScoopFree Crystal Pro Legacy | PetSafe ScoopFree SmartSpin | In practice |
|---|---|---|---|
| Entry layout | Uncovered rake box in the checked exact ASIN | Enclosed spherical sifting design with an entry about 12 in above the floor | An open rake box is not the same as an elevated enclosed entrance. |
| Litter | Compatible crystal litter only | Premium clumping litter recommended | Different waste-handling materials are needed for the two systems. |
| Routine waste care | Crystals absorb urine while the rake moves solids into the waste trap | 6 L sealed waste drawer | With crystals, urine is absorbed in the tray, whereas SmartSpin gathers clumps in its drawer. |
| Records | Local visit counter with no app | Weight and visit records through the Pet Companion app on 2.4 GHz Wi-Fi | Remote information is what SmartSpin adds. |
