- Skip if: you want to use your own clumping litter
- HTML version: https://robotsforthat.com/robot/petsafe-scoopfree-crystal-smart/

## Verdict

A simple rake box that pushes waste under a lid in a disposable crystal tray, with an app that logs visits and warns when the tray is full. It is low effort and low odor, but you are locked into PetSafe crystal trays, so running costs add up compared with clumping litter globes.

## Pros

- App alerts and visit history
- Good odor control in Tom's Guide testing
- No scooping, tray swaps about monthly
- Low profile open version fits small spaces

## Cons

- Works only with PetSafe crystal litter
- Ongoing tray cost
- Waste can stick to the rake (Tom's Guide)
- App cannot tell which cat used the box (TTPM)
