Meowant
The biggest Meowant has a 106-litre drum and a 30 lb rating, matching the Litter-Robot 5 on paper, with an 8.27-inch entry step. The claim it cannot back with its own numbers is the bin: 6.7 litres rated for up to 14 days with one cat. Meowant also quotes the noise twice, 36 dB in the description and 40 dB or less in a badge.

Best for: One large cat that needs room inside the drum
Meowant says the sensor detects cats from 3.3 lb and sets a minimum age of 4 months. At the usual rate of about a pound a month, that means leaving automatic cleaning off until roughly 4 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 them6.7 L ÷ (cats × 0.7 L a day). The maker claims up to 14 days for one cat, which is more generous than this arithmetic supports. 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 Meowant MW-SC09 Plus yet. This section stays empty until there is something real to put in it.
