Hands-on Review
The iRobot Roomba Combo j9+ has excellent obstacle avoidance, superb dirt-detecting vacuuming and a smart retracting mop that keeps carpets dry. But its light pad-mopping and premium pricing make it a hard sell in Singapore against Chinese omni robots that mop far better for less.
The iRobot Roomba Combo j9+ is iRobot’s flagship 2-in-1 vacuum and mop, best known for its class-leading obstacle avoidance and a clever retracting mop arm that lifts the pad up onto the robot’s back so carpets never get wet. It self-empties into its dock and refills its own water tank, aiming for genuinely hands-off cleaning.
In iRobot’s range the Combo j9+ sits at the top, and historically Roomba has been the premium, dependable name in robot vacuums. In Singapore, though, it competes against Roborock, Dreame and Ecovacs omni robots that mop with spinning, self-washing pads — so the j9+ occupies an awkward spot: brilliant at vacuuming and avoidance, but behind on mopping and value.

Who it’s for
- Buyers who value best-in-class obstacle avoidance (pet mess, cables, clutter)
- Homes with a mix of carpet and hard floor where dry carpets matter
- People who trust the Roomba name and app ecosystem
- Skip it if mopping quality is a priority — spinning-mop rivals clean far better
- Skip it if you want the best value; it’s expensive for what it mops
Vacuuming & obstacle avoidance
As a vacuum the j9+ is excellent. Its dirt-detection ramps up suction over grubby patches, and it’s superb at lifting hair and grit from hard floors and low carpet. But the real standout is PrecisionVision navigation — it’s among the very best at dodging cables, shoes, socks and, notably, pet waste, which iRobot backs with a pet-mess guarantee. For cluttered homes this confidence is genuinely reassuring.
Mopping
Here the j9+ falls behind. It mops with a single flat pad that wipes the floor rather than scrubbing, so while it handles light dust and the odd fresh mark, it can’t match the pressure-scrubbing of spinning-mop rivals on dried spills or that hazy film. The clever bit is the retracting arm that lifts the pad up over carpet so rugs stay bone dry — a real advantage for mixed-floor homes. But you also rinse the pad by hand; there’s no self-washing.
Dock & maintenance
The dock self-empties into a bagged bin that lasts around two months, and refills the robot’s onboard water tank for mopping. It’s cleaner and simpler than the big omni docks, but does less: no mop washing and no mop drying, so you manage the pad yourself. In Singapore’s humidity that means rinsing and drying the pad promptly to avoid smells.
App & noise
The iRobot Home app is mature and easy, with good mapping, keep-out zones, room cleaning and helpful routines, plus Alexa and Google support. Noise is moderate for vacuuming and the self-empty is a short loud burst, as with all bagged docks. Overall the software experience is polished and beginner-friendly.
Pros and cons
Pros
- Best-in-class obstacle avoidance, including pet waste
- Excellent vacuuming with dirt detection
- Retracting mop keeps carpets completely dry
- Mature, easy iRobot Home app and long-lasting dust bag
Cons
- Pad-wipe mopping is far weaker than spinning-mop rivals
- No mop washing or drying — you rinse the pad by hand
- Expensive relative to what it mops
- Ongoing bag and pad costs
Price in Singapore
In Singapore the Combo j9+ sits in the premium bracket, often $1,300–$1,800, which is steep given rivals that mop better cost the same or less. If iRobot’s navigation and carpet-dry mopping are what you specifically want, watch for sales. Buy from iRobot’s official Lazada/Shopee stores or authorised retailers for local warranty, and check the latest price.
Alternatives to consider
- Roborock Qrevo — Mops far better with self-washing spinning pads at a similar or lower price.
- Dreame L40 Ultra — Swing-out edge mopping and carpet-safe detachable pads for a more complete clean.
- Ecovacs Deebot T30 Omni — Value omni robot with high suction and a self-wash, self-dry dock.

Frequently asked questions
Is the iRobot Roomba Combo j9+ worth it in Singapore?
It depends on your priorities. For obstacle avoidance and vacuuming it’s superb, and the retracting mop is great if you have carpet. But its light pad-mopping and premium price make it hard to recommend over spinning-mop omni robots that clean floors better for the same money.
How good is the mopping?
It handles light dust and fresh marks but wipes rather than scrubs, so it struggles with dried spills and floor haze compared with spinning-mop rivals. The upside is the retracting pad that keeps carpets fully dry, which is genuinely useful in mixed-floor homes.
Is it good for HDB flats?
The navigation and vacuuming suit any flat, and dry-carpet mopping is handy if you have rugs. But if your floors are mostly tile or vinyl and you want proper mopping, a spinning-mop robot is the better fit.
What are the running costs?
Budget for replacement dust bags (roughly every two months), mop pads, and cheap filters and brushes. There’s no self-wash system, so the pad is your ongoing manual task.
Where should I buy it for warranty?
iRobot’s official Lazada/Shopee stores or authorised retailers for local warranty and support. Grey imports can complicate service and app registration.
The verdict
The iRobot Roomba Combo j9+ is a superb vacuum with the best obstacle avoidance in the business and a genuinely clever carpet-dry mop. But in Singapore, where spinning-mop omni robots clean hard floors far better for the same or less, its weak pad-mopping and premium price hold it back. A good-but-not-great 3.9 — buy it for the navigation, not the mopping.
