- ✓AdaptiLift 3.0 chassis climbs double-layer thresholds up to 3.46 inches - the best in the industry
- ✓Reactive AI 3.0 recognizes over 300 object types using tri-laser structured light, an RGB camera, and VertiBeam side laser

- ✗Small 228ml onboard dustbin and 70ml water tank lean heavily on frequent dock returns
