iRobot's newest machine posts the highest suction figure on this entire site. Its other four describe suction in adjectives. That split is the whole comparison.

iRobot publishes a suction figure for one of the five Roombas we cover - 30,000 Pa on the Max 715 Pet, the highest on this site - and describes the other four in adjectives. eufy publishes a figure for two of its three, plus the only climb height, mop lift and runtime in this comparison. eufy is the easier brand to shop.
Something changed at iRobot recently, and this comparison is the clearest place on the site to see it. For years the company refused to publish suction in pascals at all, describing it instead as a multiple of an earlier Roomba - a comparison to a baseline that itself had no published figure. Then the Roomba Max 715 Pet arrived stating 30,000 Pa, which is the highest number any maker on this site prints.
The rest of the range did not follow. The Max 705 still says "extreme power-lifting suction". The 105 Vac says nothing numerical at all. The Combo j9+ says it is 100 percent stronger than a Roomba Combo i series machine, which tells you nothing unless you know what the i series pulls, and iRobot has never said.
One figure, four adjectives
Stated suction, both brands, every model we cover
7 of 8 models publish this figure. Every number below links to the page it came from.
Compiled from the manufacturers’ own published material — every row carries the date its figure was read. We have not measured any of these figures ourselves, see how we pick. Found an error? Tell us and we will correct it.
Read the eufy rows and the Roomba rows as two different documents, because that is what they are. eufy gives you 15,000 Pa on the Omni C28 and 8,000 Pa on the X10 Pro Omni, and then an honest blank on the 11S MAX, which is an old bump-and-turn machine that predates the spec race. iRobot gives you one enormous number and then prose.
Where eufy publishes and iRobot does not
Suction is not the only gap, and the others matter more for deciding whether a robot suits your house.

Counted from each maker's own product pages and listings. Individual figures are sourced on each model spec sheet. The eufy X10 Pro Omni accounts for every one of eufy's climb, mop lift and runtime entries - and see the stock note below before buying it.
The bottom two rows are iRobot's, decisively. Every Roomba here describes its brushes and names its navigation system, and four of the five state a dock interval in days - 90 days on the Max 715 Pet with a sealed AllergenLock bag, 75 on the 105 Vac, 60 on the j9+. eufy states no interval on any model. If what you want is a machine that tells you how often you will touch it, iRobot is the better-documented brand.
The two brands are furthest apart at the bottom
At the entry end the comparison gets genuinely strange. The eufy 11S MAX has no mapping at all - it is a bump-and-turn robot that cleans in a random pattern and finds its way back to a charging dock, with no suction figure and no described brush. The Roomba 105 Vac at a somewhat higher price has ClearView LiDAR, builds up to three maps, cleans in rows and empties itself for a stated 75 days.
On published specification that is not close, and the 105 Vac is the better machine. The 11S MAX earns its place here on a different argument: it is one of the few robots left that does one job, has almost nothing to go wrong, and costs accordingly. For a one-bedroom flat with no thresholds that is a defensible purchase, and we say the same thing in best budget robot vacuums.
How we picked
Criteria first, products second. These are the things we ranked on, stated before anything is recommended.
Count published rows across each brand's whole current range. A brand that prints a figure on its newest flagship and adjectives on everything else is harder to shop than one that prints consistently.
Compare only where both makers publish. Where one is blank we say so rather than substituting an estimate.
Refuse relative suction claims. "Twice the power of our previous model" is not a specification unless the previous model published one. Neither brand gets credit for these.
Weigh millimeters above pascals. Climb height and mop lift are physical dimensions that compare honestly between brands; a Pa figure comes from each maker's own rig.
Stock status is stated, not hidden. Where a model we would otherwise rank is unavailable, we say so on the page rather than quietly dropping it. See how we pick.
What we did not do: test any of these machines. We do not own one, we do not have a lab, and nothing on this page is written as though we did. The full method.

Top pick
iRobot Roomba Max 715 Pet
The only Roomba with a stated Pa figure
Dual rubber anti-tangle brushes and a 90-day allergen-sealed dock — and the one place iRobot has printed an actual suction number instead of a multiple.
HydroJet roller rinses itself during the run instead of only at the dock
A stated 15,000 Pa, which is a real figure rather than a multiple
Five-function station: mop washing, hot-air drying, dust emptying, tank refill and wastewater collection
What it does not
No published threshold height and no published mop-lift height
No published runtime, bin capacity or body height either
The roller is a consumable and eufy does not state a replacement interval
Who it is for
Hard floors that get genuinely dirty, on a budget that will not reach a flagship omni station.
Skip it if
Your home has thresholds or deep carpet. eufy publishes no climb height and no mop-lift height for this model, so you cannot check either before you buy.
Its retracting mop is still the most interesting piece of engineering iRobot sells - the pad lifts onto the top of the robot rather than hovering a few millimeters above the carpet, which is the only design here that removes the risk entirely rather than reducing it. It is the skip for two reasons. Its suction is stated only as "100 percent stronger than the Roomba Combo i series", which is a comparison to an unnamed baseline rather than a figure. And when we last checked prices for this page the buy box was offering a used unit rather than a new one, at four-figure money. We do not rank a used-only listing.
Which brand for which buyer
Allergies, or a house where the bin should stay sealed - Roomba, specifically the Max 715 Pet. Its sealed AllergenLock bag at a stated 90-day interval has no equivalent from eufy in our registry.
Thresholds between rooms - eufy, but only the X10 Pro Omni, and only when it is back in stock. It carries the sole published climb height across both brands. Check it against every other model in our threshold table.
You want to know how often you will empty it - Roomba. Four of five state a dock interval; no eufy states one.
Mopping as a real job - eufy's X10 Pro Omni publishes 12mm of lift, and the Roomba Combo j9+ retracts its pad onto the robot's back entirely. Those are the two honest answers, and one is out of stock while the other is used-only.
Minimum spend, minimum complication - the eufy 11S MAX. No maps, no app dependency, no mop, no dock to plumb.
Most machine for around six hundred dollars - the Roomba Max 715 Pet or the eufy Omni C28. The Roomba publishes the bigger suction figure and the sealed bag; the eufy publishes a real figure of its own and costs less.
Questions people actually ask
+ Is eufy better than Roomba?
On checkable specification eufy publishes more of what decides a purchase - a climb height, a mop lift and a runtime, none of which iRobot states outside one model. On ownership detail iRobot publishes more: every Roomba describes its brushes, names its navigation and mostly states a dock interval. Which is better depends on whether your problem is getting into rooms or keeping the thing running.
+ Why does the Roomba Max 715 Pet claim 30,000 Pa when other Roombas claim nothing?
iRobot has not explained the change, and we will not invent a reason. What is observable is that the Max 715 Pet is the only Roomba in our registry that states a Pascal figure, it is the newest, and it is the highest figure published by any maker we cover. Treat it as iRobot's own measurement on its own rig, not as a number comparable to Roborock's or eufy's.
+ Which is cheaper to own, eufy or Roomba?
Neither brand publishes enough for us to answer that honestly. Bags, filters and brushes are consumables on both sides and neither maker publishes a full replacement schedule with prices. What we can say is that iRobot sells first-party replacement batteries for its robots with model-specific part numbers, which is more than most brands here offer - see when a robot vacuum battery dies.
+ Does eufy or Roomba handle pet hair better?
Both have a real anti-tangle answer. eufy's Omni C28 has a DuoSpiral Detangle Brush and the X10 Pro Omni an auto-detangling roller with a Pro-Detangle Comb; every Roomba here runs dual rubber brushes, and the Max 715 Pet adds an anti-tangle side brush and the sealed allergen bag. For a shedding house the Max 715 Pet is our pick of the two brands, and our pet hair roundup ranks it against everything else.
+ Is the eufy 11S MAX still worth buying?
Only for a specific house: small, single-level, no thresholds, and no interest in maps or an app. It has no mapping, no published suction figure and no self-emptying dock. What it has is simplicity and a low price. If you want the robot to clean in rows or remember your floorplan, the Roomba 105 Vac does both for modestly more.
