Pros & cons
iRobot Roomba j9+
- ✓Exceptional carpet cleaning — dual rubber extractors are best-in-class for pet hair
- ✓P.O.O.P. guarantee replaces the robot if it runs over pet waste
- ✓Excellent smart home integration with Alexa, Google Home, and Siri
- ✓iRobot OS learns your cleaning habits and suggests schedules
- ✓Clean Base auto-empty system is reliable and relatively compact
- ✗No mop function at this price feels like a miss compared to competitors
- ✗Camera navigation is slower and less efficient than LiDAR
- ✗120-minute battery limits coverage to about 1500 sq ft per run
- ✗iRobot subscription pushes premium features behind a paywall
Roomba 105 Vac
- ✓Real ClearView LiDAR mapping, not gyroscope
- ✓AutoEmpty dock rated for 75 days between bag changes
- ✓Remembers up to 3 floor maps
- ✓Maps a 1,000 sq ft space in about 10 minutes
- ✓Meaningfully cheaper than iRobot's j-series or Max-series self-empty vacuums
- ✗No carpet detection
- ✗Vacuum only - the 105 Combo is the mopping version at a higher price
- ✗iRobot doesn't publish suction power, noise level, or dustbin capacity
- ✗"70x more suction than the 600 series" is a marketing comparison, not a measurable spec
