Rotating drum~$699homerunPET
The CS106 is named for its 106-litre dome, which homerunPET bills as the largest on sale, and it refills its own litter: a 4.5-litre reservoir feeds the 8-litre bed when a sensor reads it low. Four weight sensors and an entrance radar stop the cycle if a cat moves in, and a physical bumper keeps the dome from closing fully. It is rated for cats from 3.3 lb and 6 months up to 25 lb, and the 12-litre bin for up to 20 days with one cat. At $699 it costs the same as the CATLINK Scoop Robot Pro, the other self-refilling drum here.

homerunPET says the sensor detects cats from 3.3 lb and sets a minimum age of 6 months. At the usual rate of about a pound a month, that means leaving automatic cleaning off until roughly 6 months. Below the threshold, a kitten may not register at all, and the box could start a cycle with it inside.
Detection: weight. The maker states anti-pinch protection on the moving part, by sensor or by design.
How minimum weights work, and what to do below them12 L ÷ (cats × 0.7 L a day). The maker claims up to 20 days for one cat, within reach of the arithmetic. Where 0.7 L comes from.
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.
