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 2 Essential

  • Excellent value for money and highly affordable
  • Good, effective suction for daily cleaning
  • Dual function vacuums and mops floors with good results
  • Compact, low-profile design fits beneath most furniture
  • Compact charging dock is easy to position

What customers don't like about iRobot Roomba Combo 2 Essential

  • Navigation is less sophisticated than premium models and tends to hit obstacles or repeat areas
  • No advanced customizable mapping or intelligent management of no-go zones
  • Unexceptional performance on carpets and rugs
  • Automatic emptying at the dock may not always operate smoothly

Verdict

The iRobot Roomba Combo 2 Essential is an entry-level 2-in-1 hybrid robot vacuum and mop featuring a 4-Stage Cleaning System with four selectable suction levels and three mopping water-flow settings. Key specifications include a 120-minute battery life, a 2.4 GHz Wi-Fi requirement, and an included AutoEmpty dock capable of holding up to 60 days of dirt and debris. Main advantages highlight its automatic dirt disposal, neat row-by-row cleaning pattern, and the convenience of simultaneous vacuuming and mopping. However, notable drawbacks include below-average battery performance on high suction, a lack of custom smart mapping capabilities (such as no-go zones or room-by-room selection), and an inability to automatically wash or dry its own mop pad.
