The brand that invented the category now sells the least checkable spec sheets in it. That is the whole of the case against, and it is not the whole story.

Sometimes. A Roomba is worth it if you need the retracting mop, a sealed allergen-rated dock bag, or an established service network — iRobot is the only maker here offering the first two. It is not worth it if you want to verify what you are buying: iRobot states suction as a multiple of an unnamed baseline and publishes no climb height for any model.
Roomba is the word most people use for the whole category, the way Hoover once was. That matters commercially and it matters here, because it means a lot of people are not really asking whether to buy a robot vacuum — they are asking whether to buy a Roomba, having already decided on the idea. It is a fair question and it has a real answer, but the answer is conditional and the conditions are specific.
If the prior question is still open — whether any of these machines earns its place — that is are robot vacuums worth it, and it is the better page to start with.
The case against, stated plainly
iRobot publishes less than its competitors about what its machines do. That is the case, and it is narrower than brand-war arguments usually are.
Suction. Most of the range states a multiple — seventy times more power-lifting suction, four times more, one hundred percent stronger than a previous generation — without naming the baseline. That cannot be compared with a Pascal figure or with another multiple.
Climb height. Not published for any Roomba on this site. If you have a tall door sill, there is no figure to check it against, and our threshold table has iRobot rows that read "Not published" the whole way down.
Mop lift. The Combo j9+ describes a retraction mechanism but states no height, so a household with rugs cannot check it.
Price. At the entry and flagship tiers, a competitor machine costs less and publishes more.
None of that says a Roomba cleans badly. It says you are asked to take the central performance claims on trust, at a premium, from a brand whose competitors are not asking that.
The case for, which is more substantial than it looks
Three things iRobot offers here have no equivalent in our registry from any other maker.
The retracting mop. On the Combo j9+ the mop pad lifts onto the top of the robot rather than rising a few millimeters. Every rival's mop lift is a number between 10mm and 17mm, which is a gap above a carpet — this one is not on the underside at all. For a mixed carpet and hard floor house that is a categorical difference, not an incremental one.
The sealed allergen bag. The Max 715's AllergenLock bag is stated as sealed and rated to 0.7 microns, at a 90-day interval. It is the most precise filtration claim any maker on this site makes, and if somebody in the house reacts to dander it outranks everything else on the spec sheet.
Parts and service. iRobot has been selling these in the US longer than anyone, with a correspondingly established network for brushes, filters, bags and repairs. We have not tested that network and cannot rate it, but its existence is a fact and it is a reasonable thing to weigh if you keep appliances for years.
It depends heavily on which Roomba
Treating Roomba as one product is the most common mistake in this decision. iRobot currently ships both the best and the worst brush construction on this site, within the same range, in the same year.
The brush on each Roomba we cover
4 of 4 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.
Dual rubber anti-tangle brushes on the Max models — genuinely good hardware, and iRobot is one of only two makers here that addresses the side brush as well. A Multi-Surface bristle brush on the 105, which is the construction that winds hair into a collar, with no anti-tangle claim attached. Buying "a Roomba" for a shedding house without checking which brush it has is how people end up disappointed by the brand rather than by the model.

How we picked
Criteria first, products second. These are the things we ranked on, stated before anything is recommended.
What is actually verifiable before purchase, since that is the basis this whole site recommends on.
What iRobot offers that nobody else does — the retracting mop, the sealed allergen bag, the parts and service network.
The price of the nearest equivalent from a maker that publishes everything, at the same tier.
Whether the specific Roomba in question has the right brush for the house it is going into, because iRobot ships both the best and the worst construction here.
No durability or reliability claims, in either direction. We have not run these machines for years and will not pretend to know.
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.
This is the model that makes the question worth asking, and the answer for it specifically is no. Its retracting mop is genuinely the cleverest mopping mechanism in the category — the pad goes onto the top of the robot rather than hovering above the carpet. But it is a four-figure machine that publishes no suction figure and no climb height, and at that money you can buy a flagship from another maker that publishes both plus a mop lift. Buy it only if the retracting mop is the specific thing you need.
So: worth it?
Buy a Roomba if you want the retracting mop, if somebody in the house needs the sealed allergen bag, or if a long-established service network genuinely matters to how you buy appliances. Those are real reasons and no competitor here matches them.
Do not buy one because it is the name you know. That premium buys familiarity, and at the entry and flagship tiers it costs you both money and the ability to check what you are getting. The middle of the range — the Max 715 Pet — is where iRobot is genuinely competitive on its own merits rather than on its reputation, and it is the one we would put in most houses.
Questions people actually ask
+ Is a Roomba worth the money?
It depends which one and why. The Max 715 Pet at around $600 is genuinely competitive and its sealed 0.7-micron allergen bag has no equivalent from another maker here. The entry 105 and the four-figure Combo j9+ are both beaten on price and on published specification by rivals, so those two are worth it only if you specifically want the brand or the retracting mop.
+ Why is a Roomba more expensive than other robot vacuums?
Brand, an established US parts and service network, and a couple of mechanisms nobody else offers — chiefly the retracting mop and the sealed allergen bag. What the premium does not buy is a more complete spec sheet: iRobot publishes less about suction and climb height than its competitors do.
+ Which Roomba should I buy?
The Max 715 Pet for most houses — dual rubber anti-tangle brushes, an anti-tangle side brush and the sealed 90-day allergen bag. The 105 Vac only if your floors are hard, nothing sheds, and you want the cheapest mapping Roomba. The Combo j9+ only if you specifically need the mop that retracts onto the robot's back.
+ Is Roomba better than Roborock?
Not on published specifications, at any tier we compare. Roborock states suction in Pascals, climb height and mop lift in millimeters; iRobot mostly states multiples of an unnamed baseline. iRobot wins on the retracting mop, the allergen bag and service reach. Our full tier-by-tier comparison covers where each lands.
+ Do Roombas handle pet hair well?
The Max models do — dual rubber anti-tangle brushes plus an anti-tangle side brush is among the best hardware on this site. The entry 105 does not: it uses a bristle brush with no anti-tangle claim. The brand answer is meaningless here; only the model answer counts.
+ How long does a Roomba last?
We do not know and will not guess. We have not run these machines over a period long enough to say anything about longevity, and we do not publish durability claims we cannot source. What is checkable is that iRobot's parts and service network in the US is the longest-established in the category.
