Purobot Max Pro 2

• Tofu and Other pellet litter is supported only under stated conditions
• The manufacturer publishes a litter particle limit (length <=12 mm (0.47 in), diameter <=3 mm (0.12 in)), so litter choice is a stated constraint rather than a guess
• Entry sits 10.03 in from the floor, which matters for kittens, senior or arthritic cats
• Needs a 25.86 × 21.18 in floor area (548 sq in)
• Some features are subscription-gated: PETKIT CARE+ gates extended video playback
• Uses brand-specific consumables (PETKIT drawstring waste bags, N50 bin filter, N60 cylinder cartridge)
• Documented 8 L waste capacity
• App-connected: PETKIT app; Care+ for extended video history
• Documented 24-month warranty

• Kittens: kittens younger than 6 months prohibited; cats under 1.5 kg (3.3 lb) prohibited
