Roomba Combo j5+ Review: iRobot's Best Vacuum and Mop Combo
The Roomba Combo j5+ combines iRobot's best-in-class vacuuming with mopping capability and a self-emptying base. If you want an iRobot product that can also mop, this is the one to get. This review examines whether the Combo j5+ is worth the premium.
Key Features
Vacuum and Mop in One
The Combo j5+ vacuums and mops in the same cleaning session. The robot's smart mapping knows which rooms have hard floors (mop) and which have carpet (vacuum only), and adjusts automatically.
Self-Emptying Base (60-Day Capacity)
The Clean Base automatically empties the dustbin after each cleaning. The base holds 60 days of debris, meaning you only deal with dust every two months.
PrecisionVision Obstacle Avoidance
iRobot's PrecisionVision is the best obstacle avoidance in the industry. The Combo j5+ reliably avoids pet waste, cords, shoes, and other common hazards — backed by iRobot's P.O.O.P. Guarantee.
Smart Mapping with Room-by-Room Cleaning
The robot creates a detailed map of your home and lets you direct cleaning by room. "Clean the kitchen" or "clean everywhere except the bedrooms" works reliably.
Works with Alexa, Google, and Apple
The Combo j5+ works with all major voice assistants, including Apple HomeKit (via shortcuts). This is the most compatible robot vacuum available.
Mopping Performance
The Combo j5+'s mopping is competent but not class-leading. It uses a passive pad mop that wets the floor and wipes — effective for light cleaning but not for tough stains. For serious mopping, the ECOVACS T80S Omni with its active roller mop is superior.
For homes with mostly hard floors and light mopping needs, the Combo j5+ is adequate. For homes that need deep mopping, consider ECOVACS or Roborock alternatives.
Who Should Buy
Buy the Roomba Combo j5+ if:
- You want the best obstacle avoidance (PrecisionVision)
- You want vacuum and mop in one device
- You use Apple HomeKit (best Apple integration)
- You want proven iRobot reliability
- Your home has mixed floor types (carpet + hard floor)
Consider alternatives if:
- You want the best mopping (consider ECOVACS T80S Omni)
- You want the cheapest self-emptying option (consider Shark AV2501AE)
- You want maximum suction power (consider Roborock Q Revo MaxV)
The Bottom Line
The Roomba Combo j5+ is the best 2-in-1 robot vacuum for users who prioritize obstacle avoidance and ecosystem compatibility. While its mopping is not the best available, the overall package — vacuuming, mopping, self-emptying, smart mapping, obstacle avoidance — is excellent. For iRobot loyalists, this is the model to buy.
