Smart litter boxes
PetSafe ScoopFree Smart review
Published 20 June 2026
A different approach: disposable crystal-litter trays rather than a rotating drum. Simple, quiet and very low-maintenance, with a tray lasting around a month for one cat. Ongoing tray costs and less flexibility are the trade-offs.
Best for: Owners wanting simple, low-maintenance crystal-litter automation

Common questions
How does the ScoopFree differ from a Litter-Robot?
It uses a rake over disposable crystal-litter trays rather than a rotating drum. That makes it simpler and cheaper upfront and very low-maintenance, but you buy replacement trays, and it ties you to crystal litter.
How long does a tray last?
Around 30 days for a single cat. For multiple cats it needs changing more often, which raises the running cost, so it suits single-cat homes best.
Is the running cost high?
The disposable trays are an ongoing cost that adds up over time, the main trade-off against its low upfront price and simplicity.
