Pros
- Mops with hot water and a heated mist, which helps loosen dried-on spills
- Roller reaches out up to 45 mm toward walls, so edges get mopped
- Dock empties, washes at 176°F and dries with heat, so the mop stays clean between runs
- Climbs 3.5 cm thresholds, so it crosses most door sills
- Camera plus dual-line LiDAR recognizes over 300 kinds of objects
Cons
- At around $1,200 it costs more than most rivals with similar docks
- iRobot doesn’t publish runtime or dock tank sizes
- Sources disagree on its suction figure
