Crystal tray~$100PetSafe
At about $100 on sale, the cheapest motorised box in the catalog is also the most limited. PetSafe's own FAQ caps it at cats up to 15 lb, and it keeps the six-month kitten rule. It has no counter, no light and no app, only a rake, sensors and a disposable crystal tray.

maker's store, not a live price
Best for: One small or medium cat, on the lowest possible upfront spend
PetSafe publishes no detection weight, only a minimum age of 6 months. Run it by hand before then. Below the threshold, a kitten may not register at all, and the box could start a cycle with it inside.
Detection: sensor type not published. The maker does not state any anti-pinch protection.
How minimum weights work, and what to do below themThe maker publishes no drawer volume, so the days cannot be worked out.
The two lists above are drawn from the maker’s own pages, manuals and prices, not from owner reports. Where owner discussion has been read it appears in its own section below, so the two are never mistaken for each other.
No owner discussion has been read for the PetSafe ScoopFree Crystal Classic yet. This section stays empty until there is something real to put in it.
