PETKIT Purobot Max Pro 2 vs PetSnowy SNOW+

Both makers say their sensor detects cats from 3.3 lb, so the kitten threshold does not separate them. With two cats the PetSnowy SNOW+'s 10-litre drawer lasts about 7 days to the PETKIT Purobot Max Pro 2's 5. Every other published figure for both is in the table, with the rows where they differ tinted.
