About
What it is.
Combo j9+ sits within iRobot's Roomba lineup as a bagless, cordless combo unit pairing vacuuming with mopping in a single chassis. Its Auto-Retract Mopping System lifts the pad away from carpet automatically, while Dirt Detective, built on iRobot OS, prioritizes the dirtiest rooms rather than cleaning in a fixed pattern. The Clean Base Auto-Fill Dock handles debris emptying and water/solution refilling, extending stretches of unattended operation. It supports both Google Assistant and Amazon Alexa.
It's built for households with mixed hard floors and carpet who want the strongest pickup performance available in a combo unit, and who don't mind hand-washing the mop pad in exchange for a dock that stays sanitary and low-odor. It's not built around mop-only modes, hands-off pad cleaning, or fast mapping and cycle speed.
The verdict
The Roomba Combo j9+ ranks as the top robot vacuum for carpet, excelling in suction and carpet-safe mopping with an auto-retracting pad, but reviewers and buyers both note that mandatory vacuuming during mop cycles and manual pad washing undercut its premium positioning.

AI summary of 5 reviews · as of Jul 2026
A genuinely strong vacuum-mop combo with class-leading suction and a clever mop-retract system, held back by slow navigation, no auto mop-pad washing, and a few app rough edges.
What they praise
- Exceptional vacuuming power — dual rubber brushes and high suction handle fine debris, large debris, and deeply embedded carpet dirt better than most robot vacuums reviewers have tested
- Auto-retract mopping system lifts the pad fully onto the robot's back over carpet, reliably keeping carpets dry while vacuuming and mopping in a single pass
- Smart Scrub feature uses downward pressure and back-and-forth passes to remove dried-on stains more effectively than simple drag-pad designs
- Clean Base dock auto-empties the bin and auto-refills the water tank, reducing hands-on maintenance significantly
- Obstacle avoidance — including pet-waste detection — is among the better implementations reviewers have tested at this tier
What they knock
- No automatic mop-pad washing or drying at the dock; pads must be removed and hand-washed after each mopping run
- Navigation is slower than key competitors — initial mapping takes longer and cleaning runs average noticeably more time per session
- Filters cannot be washed and become heavily soiled faster than the claimed maintenance interval suggests, adding ongoing replacement cost
- No mop-only mode; the robot vacuums first and decides when to mop, frustrating reviewers who wanted targeted spot mopping

For you if
Look elsewhere if
You trust iRobot's brand and want a flagship combo unit for your home.
iRobot's established prestige, flagship positioning, and premium dock with auto-empty and auto-refill align with premium connoisseur expectations.
You need a proven, low-risk robot vacuum-mop that won't let you down.
iRobot is a mature, established brand with broad consensus from 847 reviews; the product is settled and widely trusted, though some durability aspects rate lower.
You want the best robot vacuum-mop combo money can buy right now.
Class-leading vacuuming power and clever auto-retract mopping system earn strong reviews, but slow navigation, no auto mop-pad washing, and app rough edges prevent top-tier perfection.
You want strong cleaning performance without overpaying for features you don't need.
Mid-to-high street price and strong vacuuming performance are offset by hand-washing mop pads, slower navigation, and non-washable filters adding ongoing costs. Consider Q5 Pro+.
You want a robot cleaner that works out of the box with minimal fuss.
Mid-tier ease of use, hand-washing mop pads after each run, and app rough edges add friction; no mop-only mode limits flexibility for quick spot cleaning. Consider Roomba Combo i5+.

What is the main catch with this model?
There's no automatic mop-pad washing or drying at the dock—pads must be removed and hand-washed after each mopping run, which reviewers see as friction against the "totally independent" promise.
