Rita's Full Review
The iRobot Roomba j9+ is the best value premium robot vacuum in 2026, earning consistent top-5 placements from CNET, PCMag, and Wirecutter. Unlike the Roborock Saros 10R which leads on hard floor performance, the j9+ is the stronger recommendation for pet owners and carpet-heavy households. Its Dirt Detective AI analyzes historical cleaning data to direct suction to high-traffic areas, while the PrecisionVision Navigation identifies and avoids obstacles including pet waste — critical for pet households. The Empty Base dock auto-empties the bin for up to 60 days autonomously. Carpet boost automatically increases suction on carpeted surfaces. iRobot's ecosystem, with multi-map storage for up to 10 floor plans and predictive scheduling based on your routine, remains the most mature home mapping software in the category. The key limitation is mopping: the j9+ vacuums only; buyers needing combined vacuum/mop functionality should look at Roborock or Ecovacs.
What Rita liked
- Best carpet cleaning performance of any robot vacuum tested by RTINGS (9.2/10 carpet score)
- Dirt Detective AI directs suction to highest-traffic zones — optimizes cleaning efficiency over time
- PrecisionVision Navigation reliably avoids pet waste and obstacles in low-light conditions
- Auto-Empty Base holds 60 days of debris — minimizes ongoing maintenance
What could be better
- Vacuums only — no mopping capability (unlike Roborock Saros 10R)
- Expensive at $699 when Roborock S8 MaxV offers vacuum + mop for similar price
- Larger profile (3.48 inches tall) can't access spaces Roborock's ultra-slim models can
