Reviews last updated: July 2026 · How we calculate this

What customers like about iRobot Roomba Combo i8+

  • Excellent suction power that thoroughly removes dirt, dust, and hair
  • Convenient automatic emptying dock (Clean Base) captures a lot of dust and reduces maintenance
  • Good navigation in well-lit spaces; the device efficiently divides the home into zones
  • User-friendly iRobot Home app for easily setting specific cleaning schedules and 'no-go' zones

What customers don't like about iRobot Roomba Combo i8+

  • The mopping function is passive (just a damp cloth) and performs worse than true mop robots
  • Navigation struggles in the dark, as the robot relies on a camera instead of LiDAR
  • Lacks advanced obstacle detection for small objects like cords or socks
  • Mapping your home for the first time can take an extremely long time

Verdict

The iRobot Roomba Combo i8+ is a 2-in-1 robot vacuum and mop featuring a premium 4-stage cleaning system, dual multi-surface rubber brushes, and 10x the power-lifting suction compared to the Roomba 600 series. Powered by iRobot OS, it utilizes vSLAM technology to build Imprint Smart Maps for efficient row-by-row navigation, supporting personalized schedules, Keep Out Zones, and voice control via Alexa or Google Assistant. Its standout feature is the Clean Base Automatic Dirt Disposal, which self-empties the vacuum's bin for up to 60 days into an enclosed anti-allergen bag, backed by a lithium-ion battery delivering up to 120 minutes of runtime with smart recharge-and-resume capability. Main advantages include exceptional debris and pet hair pickup on hard floors, an intuitive application interface, and a hassle-free self-emptying routine. However, notable drawbacks include subpar mopping performance on stubborn stains, high noise levels during the automatic emptying process, high recurring costs for official replacement bags, and a tendency for the vacuum to struggle with fine debris on low-pile or high-pile carpets.
