Pros and cons
roborock Q Revo
- Dual spinning mop pads press down and rotate, which lifts dried spots a dragged cloth just smears
- The dock washes and dries the pads, so you are not handling a wet, dirty mop after every run
- LiDAR mapping builds an accurate floor plan on the first run and holds straight lines along baseboards
- Mop pads lift on carpet, so one machine can cover hardwood and rugs without you moving anything
- The dock is large and needs a plumbing-free but permanent spot with clearance either side
- No camera-based obstacle avoidance, so cables and socks still need picking up before a run
- Owner ratings sit in the high threes rather than the fours, mostly over dock and app complaints
roborock Q8 Max+
- ReactiveAI obstacle avoidance without stepping up to the top of the range
- DuoRoller brush design reduces hair wrap noticeably compared with a single bristle roller
- Self-empty dock holds weeks of debris, which is the feature that turns a robot from a chore into an appliance
- The highest owner rating of the roborock models compared here
- Mopping is a flat dragged pad, not spinning pads — fine for dust, weak on dried spills
- The mop pad does not lift, so carpet has to be excluded in the app or the pad removed
- A small owner-rating base compared with the long-established Roomba listings
roborock Q5 Max+
- Self-emptying dock at a price where most rivals still make you empty a bin by hand
- DuoRoller brush keeps long hair off the axle better than the bristle rollers at this price
- LiDAR mapping rather than the random bump-and-turn navigation cheaper robots use
- Vacuum only — there is no mopping function at all
- No obstacle avoidance, so it will find every charging cable in the house
- Thin owner-rating base, and the dock bags are an ongoing cost
iRobot Roomba j7
- PrecisionVision identifies and steers around cords, socks and pet waste, and iRobot backs the pet-waste claim with a guarantee
- Rubber dual brushes rather than bristles, which is genuinely better on hardwood and on hair
- The most mature app in the category, with reliable room labeling and scheduling
- US service network and parts availability that no competitor matches
- Camera navigation needs light, so overnight runs in a dark house map less reliably than LiDAR
- No mopping — that is a separate machine in iRobot terms
- iRobot does not publish a suction figure, which makes spec comparison one-sided
- Owner ratings across recent Roomba listings have slipped and sit below roborock here
iRobot Roomba j9+
- Adds a self-emptying base to the j7 platform, holding weeks of debris
- Dirt Detective learns which rooms need more passes and prioritizes them
- Same rubber brush design and object recognition as the j7
- The weakest owner rating of anything in this comparison, with recurring complaints about connectivity and dock errors
- Still no mopping at a price where roborock includes washed, spinning pads
- Dock bags are a permanent running cost
iRobot Roomba Vac (Q0120)
- The lowest price of entry to the Roomba platform and app
- Light, simple and easy to set running without configuring anything
- Fits under more furniture than the taller LiDAR machines
- No LiDAR, no object recognition and no self-empty base
- Rated poorly by owners relative to its price, with complaints about coverage and repeat passes
- Small bin, which on hardwood with a shedding pet means daily emptying
Decision factors
What you actually pay
The two brands land in the same bands, so this is not a budget-versus-premium comparison. Entry sits around $180 to $250 for the basic Roomba and $300 to $400 for the roborock Q5 Max+. The middle is $400 to $550, where the Roomba j7 and roborock Q8 Max+ meet head-on. The top is $600 to $800 for the Roomba j9+ and the roborock Q Revo.
What you get for the same money differs sharply. At $400 to $550, iRobot spends the budget on object recognition and gives you no dock and no mopping; roborock spends it on LiDAR, a self-empty dock and a mop pad. At the $600 to $800 mark, roborock adds spinning mops that wash and dry themselves while iRobot adds a bin that empties itself. Which is the better use of the money depends entirely on whether your floors are hard or soft.
Running costs are where robots surprise people. Both brands need filters two or three times a year, side brushes about as often, and a main brush roughly annually. Any self-emptying dock consumes bags, which is a real subscription-like cost over a decade — roborock and iRobot both sell them, and third-party bags exist for both. roborock's mop pads are a consumable too. Budget $50 to $100 a year in parts for either brand and you will not be caught out.
Battery replacement is the long-term item nobody prices in. Both brands sell them, both are user-replaceable with a screwdriver, and both cost a meaningful fraction of a cheap robot. It is the main reason to prefer a platform with good parts supply, and on that measure iRobot is still the strongest name in the category.
Which one fits you
- Hardwood or tile through most of the house roborock Q Revo Spinning pads with a self-washing dock is the only setup here that keeps hard floors genuinely clean without you touching a wet mop.
- A puppy, or a house with toys and cables on the floor iRobot Roomba j7 Object recognition avoids the accidents that turn one bad run into an hour of cleanup, and iRobot stands behind the pet-waste claim.
- Vacuuming only, on a budget, with a dock that empties itself roborock Q5 Max+ LiDAR mapping and self-emptying for the price most brands charge for a bump-and-turn robot with a hand-emptied bin.
- A small apartment and a first robot iRobot Roomba Vac Cheapest way onto a well-supported platform. Accept that it wanders more and empties less often than the mapping machines.
If neither is right
- eufy X10 Pro Omni Spinning mops, self-washing dock and obstacle avoidance in one machine, with a far larger owner-rating base than either brand here. The strongest all-rounder if brand loyalty is not a factor.
- eufy BoostIQ RoboVac 11S Slim No mapping, no mopping, no app to fight with — just a very thin, very cheap, very well-rated vacuum that fits under low furniture.
- iRobot Braava Jet M6 If you already own a Roomba and only want mopping added, the Braava pairs with it and hands off between the two machines.
Which one should you buy?
For a home that is mostly hardwood, tile or laminate, buy roborock. Hard floors need a machine that mops as well as it vacuums, and roborock is the only one of these two brands that fields a real mopping robot — the Q Revo presses down and spins its pads, then washes and dries them at the dock. iRobot is the better buy in one specific circumstance: when the floor is never quite clear, because the j7 and j9+ recognize and steer around cords, socks and pet waste in a way no roborock here can.
Both brands make competent robots. What separates them is philosophy. roborock builds hardware-first machines that publish their suction figures, map with LiDAR and pack in mopping. iRobot builds software-first machines that see what they are driving toward and rely on a very mature app and the best parts network in the category. Neither approach is wrong; they suit different houses.
How do the two brands genuinely differ?
Navigation is the first real split. roborock uses a spinning LiDAR turret to build a floor plan by measuring distances, which works identically in a pitch-dark room and produces tidy, straight-line coverage. iRobot navigates with a camera and sensors, which is why a Roomba benefits from lights on and why it maps a house over several runs rather than in one. LiDAR maps faster and more accurately; a camera sees what LiDAR cannot — the low, soft objects on the floor.
The second split is mopping. roborock treats it as a core function with real engineering behind it: pads that lift over carpet, docks that wash and dry, water tanks sized for a whole floor. iRobot separates the jobs, selling the Braava line as dedicated mops. On hardwood that is a significant gap, because dust on a hard floor is only half the job.
The third is transparency. roborock publishes a suction figure in pascals for every machine. iRobot publishes none, arguing that brush design and airflow matter more than a headline number — which is defensible, and also makes any side-by-side spec comparison flattering to roborock. Judge iRobot on its brush design and the owner record instead.
Which brand handles pet hair better on hard floors?
iRobot's rubber dual brushes are the better design for hair on hardwood. Bristles flick fine hair around a hard floor; counter-rotating rubber extractors grip and pull it into the bin, and they do not accumulate the wrapped mat around the axle that costs you a scissors session every month. roborock's DuoRoller design on the Q8 Max+ and Q5 Max+ moves in the same direction and works well, but iRobot has been refining rubber extractors for longer.
Where roborock wins the hair problem is at the dock. A self-emptying base means the small onboard bin that fills daily in a shedding household is dealt with automatically, and roborock puts a self-emptying dock on machines from around $300. iRobot's cheapest self-emptying model in this comparison is more than double that.
What about apps, updates and long-term support?
iRobot's app is the most mature in the category and its US service network is unmatched — parts, batteries, brushes and filters remain available for old machines years after they leave the shelves. That is worth real money on an appliance you intend to keep for five or more years.
roborock's app is more feature-dense — carpet detection, no-mop zones, custom suction per room — and owners generally rate it well, though firmware updates have caused temporary problems on some models. Parts availability is good and improving, with widely stocked filters, brushes and mop pads. It is not yet iRobot's network, but it is no longer a concern.
Where does each brand fall short?
roborock's weak point is anything on the floor. Without camera-based object recognition on most of the range, a cable or a sock stops a run and a pet accident ruins one. Pick the floor up, or step up to a model that sees.
iRobot's weak point in this comparison is value at the top. At $600 to $800 the j9+ gives you a self-emptying bin, and the roborock at the same price gives you a self-emptying bin plus washed, spinning mops. On hard floors that is a hard argument to answer, and the owner ratings reflect it.
