Quick verdict
Choose the Purobot Max Pro 2 for its larger listed entry and 76 L drum. Investigate the Purobot Ultra when automatic bag packing and its 10 L waste bin are worth the higher complexity. Both use camera-based tracking and support cats from 3.3 to 22 lb according to PETKIT.
Max Pro 2 strengths
The Max Pro 2 lists a 10.51 × 10.74-inch entry, 76 L drum and 8 L waste bin. PETKIT claims up to 17 days between emptying for one cat. It is the more direct choice when entry comfort and a conventional sealed drawer matter most.
Purobot Ultra strengths
The Ultra lists a 70 L drum, 10 L waste bin and automatic waste-bag packing. PETKIT claims up to 20 days for one cat. Packing can reduce direct contact with waste, while adding proprietary bags and more mechanisms to maintain.
Tracking and connectivity
Both product pages describe 1080p cameras, individual cat identification and dual-band Wi-Fi. Camera position and software differ, so compare the current app features and privacy terms rather than assuming identical monitoring.
Maintenance reality
Neither model eliminates litter-box work. Owners still need to add litter, empty waste, clean sensors and surfaces, inspect moving parts and perform deeper cleaning. Cat acceptance may require a slow transition with the original box kept nearby.
Bottom line
Pick Max Pro 2 for the roomier published entry and simpler waste drawer; pick Ultra for automated bag packing and its larger bin. Measure the available space and the cat, then confirm current consumable costs before deciding.
