Overall ratingGood69/100
Very good80/100
- Retractable mop arm keeps carpets dry
- The new Clean Base design blends in better with the home
- Detects and prioritises the dirtiest areas
- The maps in the companion app are simple and many controls are hidden in submenus
- Mop pads must be cleaned manually
- Expensive
With new intelligent automation features and an attractive new Clean Base, the Roomba Combo J9+ vacuum/mop hybrid further refines iRobot's flagship model. But an inelegant app makes using this robot more of a hassle than it should be.
Without ratingNo rating
- Very flat
- Service station
