- Up to 295 minutes of runtime covers a large home on one charge
- Only 3.29 in tall, so it fits under most sofas and beds
- Dock empties, washes pads in 167°F water and dries them with heat
- Pads extend toward walls, so edges get mopped
- No camera, so it is likelier to run into cords and pet mess than camera models
- Pads lift only 10 mm, so thick rugs may need a no-mop zone
- iRobot doesn’t publish threshold height or dock tank sizes
