- ✓AI obstacle avoidance reliably dodges cables, shoes, and pet toys
- ✓Dual rubber brush rolls resist hair tangles better than bristle brushes
- ✓Excellent carpet detection lifts the mop pad high enough to avoid wetting carpet

- ✗Dock is very large and requires significant floor space

- ✗Manufacturer doesn't publish robot-only weight or a warranty term on the product page
- ✗Too new to the lineup to have verified long-term owner reliability reports
