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 j7+

  • Excellent suction, particularly on hard floors and carpets
  • Advanced obstacle avoidance intelligently detects and bypasses cables, socks and pet waste
  • Innovative mopping system automatically lifts the mop over carpets to keep them dry
  • Very practical self-emptying base empties after each run and greatly reduces daily maintenance
  • Smart mapping and intuitive app make it easy to define no-go zones and schedule cleaning

What customers don't like about iRobot Roomba Combo j7+

  • The mop does not scrub vigorously and is better for refreshing floors or small spills than stubborn stains
  • The water tank is quite small and needs frequent refilling with regular mopping
  • The robot may struggle to reach dirt in very tight corners or confined spaces
  • Brush cleaning can require extra effort when wet debris is combined with vacuuming and mopping
  • Relatively high price compared with other robot vacuums

Verdict

The iRobot Roomba Combo j7+ is a 2-in-1 robot vacuum and mop featuring a unique, fully retractable mop arm that lifts completely away on carpets to prevent wet messes, alongside a 30-watt motor that delivers 10x the power-lifting suction of the Roomba 600 series. Operating at a maximum noise level of 68 dB, it utilizes advanced PrecisionVision Navigation to actively identify and avoid common obstacles like charging cords and pet waste, while its bundled self-emptying Clean Base stores up to 60 days of debris in an enclosed AllergenLock bag. The main advantages of this model include its hands-free surface transitions, highly accurate obstacle avoidance backed by a pet waste guarantee, dual multi-surface rubber brushes that reduce hair tangles, and user-friendly smart mapping through the iRobot Home App. However, key drawbacks include its lower scrubbing efficiency compared to dedicated moppers, a small water tank that requires frequent manual refilling, a loud 88 dB auto-empty cycle at the dock, and a premium price point.
