Rake~$280PetSafe
Rather than a globe, this is a long, low tray with a rake, the ScoopFree crystal design rebuilt for ordinary clumping litter. It stands under 11 inches tall, and the bin can run unlined or take a regular 8-to-10-gallon kitchen bag. PetSafe says to expect emptying about once a week; it publishes no cat-weight range and no bin volume.

maker's store, not a live price
Best for: Cats that refuse enclosed boxes, in homes that want to keep their current litter
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. Its own claim is up to 7 days for one cat.
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 Clumping Self-Cleaning Litter Box yet. This section stays empty until there is something real to put in it.
