The iRobot Roomba Combo j9 is a strong choice for tech-savvy homeowners who want a true 2-in-1 vacuum-mop experience without constant manual intervention. Its smart obstacle avoidance and auto-lifting mop feature set it apart from cheaper hybrids, though the higher price and light mopping performance mean it's best suited for maintenance cleaning rather than deep floor scrubbing.
How it scored
Our full review
The iRobot Roomba Combo j9 stands out as one of the most intelligent robot vacuum and mop combinations available for modern households, designed to tackle both dry debris and wet messes without requiring you to swap out attachments or intervene manually. What truly sets this model apart is its innovative retractable mopping pad, which lifts up and out of the way automatically whenever the robot senses carpet or rugs, eliminating the age-old problem of wet mop pads dragging soggy streaks across your favorite area rug. This means you can let the j9 roam freely across mixed flooring throughout your home, transitioning seamlessly from hardwood to tile to carpet, confident that it will vacuum thoroughly everywhere and mop only where appropriate, all in a single cleaning cycle. Powering this seamless performance is iRobot's advanced navigation system, which uses precision vision mapping and smart sensors to understand your home's layout in detail, learning the names of specific rooms, furniture placement, and even recognizing common household objects like shoes, cords, and pet waste to avoid them during cleaning runs. The Roomba Combo j9 connects to the iRobot Home app, allowing you to set customized cleaning zones, schedule specific times for vacuuming versus mopping, and receive real-time updates on its progress. Its suction power has been notably increased compared to earlier Roomba generations, making it more effective at lifting embedded dirt, pet hair, and fine dust from carpets and hard floors alike, while the mopping function uses a vibrating pad technology that scrubs at a rapid pace to lift dried-on stains and sticky spots from kitchen and bathroom floors. Completing the experience is the Clean Base charging and self-emptying dock, which automatically empties the robot's bin after each cleaning session, storing debris for weeks at a time so you rarely need to handle dust and dirt directly. The base also handles the cleaning and drying of the mopping pad in select configurations, reducing the manual maintenance typically associated with robotic mops. Compact yet packed with sensors, the Roomba Combo j9 fits comfortably under most furniture while still delivering a robust cleaning session that rivals traditional upright vacuums paired with separate mop routines. For anyone juggling a busy schedule, pets, or kids who track in daily messes, this device offers a genuinely hands-off way to maintain consistently clean floors throughout the week.

What owners say
I was skeptical about combo vacuum-mops but the j9 actually lifts its pad on our area rugs without leaving wet streaks. The self-emptying base is a game changer for my allergies.
Suction is excellent and mapping is spot on. The mopping is more of a light wipe than a deep clean, but for daily upkeep it's perfect. Worth the investment.
It avoided my dog's water bowl and phone charger cables without issue. Occasionally it gets confused by a dark rug in the hallway, but overall very reliable.
Been using it for two months now and the Clean Base truly means I only empty it once every couple months. App integration with Alexa makes scheduling effortless.
Performance is solid but I wish the mopping was more thorough for sticky spills. Also the base takes up more corner space than I expected.
