UBPet
UBPet is the pet brand of the robotics maker UBTECH, and the C41 Pro is its C41 drum with an HD night-vision camera and face recognition added for $60 more. The waste bin is built into the drum and rotates with it, which UBPet holds a patent on as its anti-pinch design, and gravity sensors stop the drum when a cat steps in. It is rated for cats up to 30 lb. Video recording and cloud storage carry no subscription, and the camera can be switched off in the app.

UBPet publishes neither the lightest cat this box detects nor a minimum age. Until it does, treat it as unsuitable for automatic cleaning around a kitten and run it by hand.
Detection: weight, camera. The maker states anti-pinch protection on the moving part, by sensor or by design.
How minimum weights work, and what to do below them6.7 L ÷ (cats × 0.7 L a day). 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 UBPet C41 Pro yet. This section stays empty until there is something real to put in it.
