Pros & cons
iRobot Roomba Max 705 Vac
- ✓Strongest Roomba yet — dual rubber extractors still set the bar for pet hair on carpet
- ✓LiDAR navigation finally works in the dark, unlike every camera-based j-series
- ✓Obstacle avoidance is reliable day or night per owner reports
- ✓210-minute runtime roughly doubles the old j-series
- ✓Simpler vacuum-only design avoids the Combo's failure-prone mop dock
- ✗Owner sentiment is lukewarm (about 56% positive) — fine dust on dark hard floors is a known miss
- ✗iRobot does not publish suction specs, making comparisons guesswork
- ✗New Roomba Home app is slow and less polished than Roborock's
- ✗iRobot's financial turmoil raises long-term support questions
- ✗No mop at all when similarly priced rivals include full wash docks
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
