Oneisall
For about $240, the Ease S1 Pro claims numbers usually reserved for boxes twice the price: an 11-litre drawer, cats from 2.6 to 30 lb, and a two-year warranty. It is an open rectangular design with a full silicone liner that lifts out in seconds. This is the App Control version, with 2.4 GHz and 5 GHz Wi-Fi plus Bluetooth; Oneisall sells the same box without the app as the Ease S1 Standard for about $20 less. The page counts its safety sensors but does not say what they are.

Price and stock there may differ from the figure above.
Oneisall says the sensor detects cats from 2.6 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: sensor type not published. The maker does not state any anti-pinch protection.
How minimum weights work, and what to do below them11 L ÷ (cats × 0.7 L a day). The maker claims up to 14 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.
No owner discussion has been read for the Oneisall Ease S1 Pro yet. This section stays empty until there is something real to put in it.
