M1 Plus keeps the litter bed open and visible; PuraMax 2 uses a contained cylinder with a circular entrance. The right choice starts with the cat's size, age, confidence, litter, and current box habits—not the app dashboard.

| Entry design | Open top | Enclosed cylinder with circular entrance |
| Cat guidance | 2.2–33lb listed | Older than 6 months and at least 1.5kg per manual |
| Waste capacity | 11.23L listed | 7L listed |

| Best fit | Large or open-box-preferring cats | Cats comfortable with a contained entrance |
An open top can suit a large or enclosure-wary cat. An enclosed cylinder can contain the area better, but only if the cat enters comfortably and meets the manual's limits.
Set up the new box without automatic cycling, preserve the familiar box, and introduce movement gradually. Do not force a cat into either machine.
App records can support observation, but they do not confirm health, successful elimination, or a clean mechanism. Inspect the cat, output, litter, sensors, liner, bin, and moving parts.
Spend more when odor, hair, or monitoring is a repeated apartment problem that affects daily comfort.
Spend less when a manual routine, washable cover, or basic camera solves the same issue without subscriptions.

PETKIT
An enclosed P9902 automatic litter box with a 76L interior, 7L waste bin, low entrance, 11 listed safety sensors, app controls, a sealed rotating cylinder, and support for several clumping-litter types.
Best for: Adult cats that accept an enclosed box and supported clumping litter
Main caution: Manual does not recommend use for cats younger than six months or under 1.5kg
M1 Plus has the clearer open-top advantage and a listed range up to 33 pounds, but floor space, step height, cat mobility, and acceptance still need testing.
Follow each current manual. PETKIT specifically does not recommend PuraMax 2 automatic use for cats under six months or 1.5kg; retain manual scooping and a conventional box.
No. A person still needs to observe the cat and waste, empty the bin, clean the machine, inspect sensors and moving parts, and respond to failures.
