Let's be real: nobody actually wants to vacuum. You want clean floors, a clear conscience, and maybe a few extra minutes to sit down with a coffee before the chaos of the day kicks in. That's exactly the promise the iRobot Roomba Combo j9+ makes — and honestly, it delivers on most of it.
The Combo j9+ is iRobot's flagship all-in-one robot vacuum and mop, complete with a self-emptying base and a retractable mop pad that lifts itself out of the way when it hits carpet. It's packed with smart features like obstacle avoidance, room-specific scheduling, and voice assistant compatibility. In short, this thing is trying very hard to be the only cleaning gadget you'll ever need.
We put it through its paces in a real home — think pet hair, crumbs, muddy footprints, and the occasional rogue LEGO — over several weeks. Here's the full, sparkle-free truth about whether this robot vacuum is worth your hard-earned money.
What We Love
- ✅ Retractable mop pad is genuinely clever — it lifts automatically onto carpet so you're not dragging a wet pad across your rugs
- ✅ Excellent obstacle avoidance using iRobot's PrecisionVision Navigation; it reliably steers around pet toys, cables, and shoes
- ✅ Self-empty base holds up to 60 days of debris, meaning you can truly set it and forget it for weeks
- ✅ Strong suction handles pet hair and fine dust on both hard floors and low-pile carpet with ease
- ✅ App is intuitive and polished — room mapping, keep-out zones, and custom schedules are all easy to set up
- ✅ Works smoothly with Alexa and Google Assistant for hands-free commands
- ✅ Combo functionality means you genuinely get a decent mop and vacuum in one device, saving space and money compared to buying two robots
Watch Out For
- ❌ The price is eye-watering — this is one of the most expensive robot vacuums on the market, full stop
- ❌ Mopping performance is solid on light everyday messes but won't replace a deep manual mop for stubborn dried-on stains
- ❌ The self-empty base is large and takes up noticeable floor or counter space
- ❌ Battery life is adequate but not class-leading — larger homes may need a mid-clean recharge
- ❌ Occasionally gets confused by dark-colored rugs, mistaking them for drop-offs and refusing to clean them
- ❌ Replacement parts and consumables (filters, mop pads, bags) add up in ongoing costs
Performance Scores
The Verdict 💖
The iRobot Roomba Combo j9+ is, without question, one of the most capable and well-thought-out robot vacuums you can buy right now. The retractable mop feature alone is a genuine game-changer that solves a problem every combo robot before it fumbled — and the navigation is smart enough that you'll stop babysitting it almost immediately.
That said, 'best' and 'right for you' aren't always the same thing. If your home is mostly hard floors and you have pets or allergies, this robot will earn its keep. But if you're in a smaller space, on a tighter budget, or mostly dealing with carpet, there are excellent alternatives at half the price that will get the job done without the financial sting.
Our honest take? If you can afford it and you want the closest thing to a hands-off, fully automated clean-home lifestyle, the Roomba Combo j9+ is genuinely worth the splurge. Just go in with eyes open about the ongoing costs, set your expectations on the mopping, and let this little sparkly robot do its thing.
