Third-party reviews

Based on ratings from across the web.
Reviews last updated: July 2026 · How we calculate this

What customers like about iRobot Roomba Combo j5+

  • Effective dual cleaning: Good vacuuming performance and efficient mopping for hard floors
  • Advanced navigation: Intelligent mapping and obstacle avoidance, including pet waste and cords
  • Self-emptying base: Convenient Clean Base automatic dirt disposal lasts up to 60 days
  • Versatile functionality: Convertible bins allow for separate vacuuming or combo vacuuming/mopping
  • Quiet operation: Runs quietly

What customers don't like about iRobot Roomba Combo j5+

  • Mopping performance: Some users report it is less effective than expected
  • Setup and adjustment: May require some initial setup and monitoring to navigate properly
  • Initial cost: High price point, with some users questioning value compared to other models
  • Bin conversion: Requires manually switching bins to change between vacuuming and mopping modes

Verdict

The iRobot Roomba Combo j5+ is a 2-in-1 self-emptying robot vacuum and mop featuring a 2210 mAh lithium-ion battery, a 389 ml vacuum bin, and a swappable 276 ml combo mopping bin. Its main characteristics include VSLAM-based PrecisionVision Navigation for real-time 3D obstacle avoidance (such as pet waste and cords) and an automatic Clean Base that holds up to 60 days of debris. Prominent pros are its effective dual multi-surface rubber brushes, proprietary Dirt Detect technology that intensifies suction on heavy messes, and a feature-rich app with custom No Mop Zones. However, notable cons include a highly manual mopping experience that requires physically swapping the dustbin for the water tank, a lack of an automatic mop-lifting mechanism over carpets, and loud operation during its self-emptying cycle.
