Roborock vs Roomba
One brand leads on mapping and value, the other on obstacle recognition. The right answer depends on what is on your floor.
Roborock and iRobot are the two names most people compare when buying a robot vacuum, and the comparison is genuinely close at every price point. The brands are not better or worse in the abstract — they have made different bets about what matters most.
Roborock's bet is on LiDAR mapping and specification per pound. iRobot's bet is on camera-based obstacle recognition and a simpler experience. Which one you should buy depends on what is usually lying on your floor.
Navigation: LiDAR against camera
Roborock's mainstream models use a LiDAR turret on top of the robot. It measures distance directly with a laser, builds an accurate map quickly, and cleans in orderly rows. The map is reliable enough that drawing a precise no-go zone around a pet bowl actually works.
iRobot's mainstream models use a front camera and visual navigation. The map improves over several runs rather than being right on the first one, and it is more sensitive to lighting and to furniture being moved. In exchange, the camera can attempt to recognise what it is looking at rather than only how far away it is.
For most homes, LiDAR gives you a usable map sooner and a more consistent cleaning pattern. That is the more important of the two capabilities, because a map you trust is what makes room selection and no-go zones worth using.
Obstacle avoidance: the one place Roomba clearly leads
If your floor regularly has charging cables, socks, pet toys or — in the worst case — pet waste, camera-based obstacle recognition is the single most valuable feature in the category. iRobot's higher-tier models identify these hazards and route around them, which is what makes unsupervised cleaning realistic in a busy household.
LiDAR alone cannot do this. A LiDAR robot knows a wall is 40cm away; it does not know that the thing on the floor is a phone charger. Roborock addresses this on its upper tiers with camera systems of its own, so the distinction is about price tier as much as brand — but at the entry and mid range, iRobot is the brand that puts recognition first.
Mopping: Roborock takes it more seriously
Roborock has pushed harder on mopping across its range, from vibrating pads at the entry level through to rotating mop pads and self-washing docks higher up. If mopping hard floors matters to you, Roborock offers more capable options and more of them.
iRobot's approach has been more conservative, and its combination models are generally judged on vacuuming first. Neither brand's robot mop replaces a manual mop for dried-on spills, and it is worth being clear about that before paying a premium for mopping hardware.
Docks and hands-off convenience
Both brands offer self-emptying docks, and both have moved up to docks that also wash and dry the mop pads. The practical differences are size and consumables.
Higher-end Roborock docks are large units that need plumbing or at least a water tank you fill and empty, and they take up real floor space. iRobot's self-emptying bases are simpler, using a bag that you replace periodically. If you want the absolute minimum of intervention, the more elaborate Roborock docks go further; if you want a dock that fits under a sideboard, iRobot's is easier to place.
Check clearance before ordering either. A dock that does not fit where you intended ends up in a hallway.
App and ecosystem
Both apps support room naming, per-room scheduling and no-go zones, and both work with Alexa and Google Home. Roborock's app exposes more granular control — suction and water level per room, multi-floor maps, and detailed cleaning history — which some people find powerful and others find cluttered.
iRobot's app is more guided and, in our reading of owner reports, less prone to the settings sprawl that makes people give up on configuration. If you want to set it and forget it, that is a point in iRobot's favour.
On standards: both brands have added Matter support by firmware on some models. Support varies by generation, so verify for the specific model rather than the brand.
Which to buy
Choose Roborock if you want the most capability per pound, you value accurate mapping you can rely on for zones and room selection, your floors are usually clear, and mopping matters to you.
Choose iRobot if your floors regularly have obstacles on them, you have pets or small children, you want to run cleaning while out of the house, and you would rather have a simpler app and a dock that fits in a tight space.
The tie-breaker question is this: what is usually on your floor when the robot runs? If the honest answer is 'not much', LiDAR and specification win and that means Roborock. If the honest answer is 'a bit of everything', obstacle recognition earns its premium and that means iRobot.

Frequently asked questions
Is LiDAR better than camera navigation?
For mapping, generally yes — it is faster, more accurate and less affected by lighting. For recognising objects, no — LiDAR measures distance and cannot tell a cable from a floorboard. The best robots use both, which is why the upper tiers of both brands include a camera alongside LiDAR.
Which brand is better for pet hair?
Both handle pet hair well on hard floors, and both offer rubber extractors or brushes designed for it. The bigger factor is whether the robot can be trusted around the things pets leave on the floor, which favours obstacle recognition. If pet waste is a realistic risk, that feature matters more than suction figures.
Do both brands work with Alexa and Google Home?
Yes. Both also have Matter support on selected models by firmware update. Because support is model- and generation-specific, check the specific product page rather than assuming it applies across the range.
