Roborock is the only brand on this site where a suction ranking is defensible, because every figure comes from one maker's own method. The surprise is where the range goes quiet.
Disclosure — some links on this page go to Amazon, and we earn a commission if you buy through them. It costs you nothing extra and it does not change what we recommend or in what order. The full disclosure.
The Roborock Q7 M5+ is the pick for most houses: it publishes a suction figure, a climb height, a body height, a named anti-tangle brush and a stated dock interval, and it is the cheapest Roborock that self-empties. The Qrevo CurvX is the most capable and publishes every row we track.
Almost every brand page on this site runs into the same wall: the manufacturer will not tell you the thing you need to know. Shark publishes no suction figure for any model. iRobot publishes one for exactly one machine. Roborock is the exception - it states a Pascal figure for all seven models it currently sells here, and that single fact is what makes this page worth writing.
It also makes this page fair in a way that cross-brand suction rankings are not. There is no shared industry standard for measuring suction, so a Pa figure is really a measurement of one company's own test rig. Set two brands side by side and you are comparing rigs. Set seven Roborocks side by side and you are comparing machines.
Where Roborock goes quiet inside its own range
Publishing a suction figure for everything does not mean publishing everything. Roborock fills the rest of the spec sheet very unevenly across its own lineup, and the pattern is not the one you would expect.

Compiled from each model's own Roborock page and Amazon listing. Every individual figure is sourced on that model's spec sheet. Three further Roborocks we once covered - the Qrevo Curv, Qrevo Master and Qrevo S - are no longer sold and are excluded.
Read the third row again. The Q7 M5+ fills as many of those columns as the Saros 10R, which costs many times more, and it is the only Roborock under five hundred dollars that publishes a climb height at all. The two mid-range machines directly above it in price - the QV 35A and the Curv S5X - publish nothing but a Pascal figure and a dock description.
Suction, ranked the one way it is fair to rank it
Every Roborock currently sold here, by stated suction
7 of 7 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.
Three things in that ledger are worth saying out loud. The top two are tied, so suction is not what separates the two flagships - the climb height is. The Q7 M5 and Q7 M5+ post the same 10,000 Pa, so the plus is buying the dock and the published dimensions rather than more power. And the bottom two figures, 8,000 and 7,000 Pa, sit on machines that cost considerably more than the 10,000 Pa Q7 M5.
What the dock is actually deciding
Once suction stops separating models, the dock does. Roborock sells four distinguishable dock tiers here, and the price differences between these machines are mostly dock differences rather than robot differences.
Charging only - the Q7 M5. You empty a small onboard bin by hand every few runs. Nothing is wrong with this if the robot lives in a studio.
Auto-empty into a bag - the Q7 M5+, stated at up to seven weeks into a 2.7L bag. This is the single biggest quality-of-life jump in the range and it is the cheapest one Roborock sells.
Auto-empty plus mop washing - the QV 35A and Qrevo Curv S5X. The dock now washes the mop pads as well, so you are not wringing out a dirty pad by hand.
Hot water plus drying - the Qrevo CurvX and Saros 10R. Washing with heated water and then drying the pad, which is what stops a damp pad smelling between runs.
Worth noting what none of these docks publishes: how long its battery lasts, how many charge cycles the pack is rated for, or what a replacement costs. That is a range-wide blank, and we cover what it means for ownership in when a robot vacuum battery dies.
How we picked
Criteria first, products second. These are the things we ranked on, stated before anything is recommended.
Rank on how much of the spec sheet is filled at that price, not on the headline figure. Every model here comes from one company, so a blank row is a choice rather than a house style.
Weigh physical dimensions above pascals. A climb height in millimeters and a body height in millimeters decide whether the machine reaches a room and fits under a couch. Suction decides how well it cleans the rooms it can reach, and only after it gets there.
Compare Pa figures only inside this page. All seven come from Roborock's own measurement method, so they rank against each other honestly. Carried across to another brand they mean much less - see our suction comparison for why.
Credit described mechanisms over trademarked names. A "JawScrapers Comb anti-tangle main brush" tells you there is a comb scraping the roller. "Smart obstacle avoidance" tells you nothing you can check.
No durability, battery-life or service claims. We have not owned any of these machines and will not guess how they age. 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.

Roborock Q7 M5+The Q7 M5's LiDAR and anti-tangle hardware, plus the self-emptying dock the plain M5 does not come with — and a stated bag capacity to go with it.
Roborock Qrevo CurvXThe highest published suction figure here paired with the highest published mop lift, which is the combination a mixed-floor home actually needs.
It has a hot-water mop washing dock with auto drying, which is real hardware. It is the skip because it is the emptiest spec sheet Roborock currently sells: 7,000 Pa - the lowest figure in the range - no climb height, no mop lift, and a main brush the listing never describes. Roborock will tell you what the brush is on six of its seven models. On this one it will not, and at this price that is a strange place to save words.
Roborocks that are not on this list
The Qrevo Curv S5X is a genuinely good spec sheet - 18,500 Pa, a zero-tangling main brush with a FlexiArm side brush, and a self-emptying dock stated at ten weeks with mop washing. It is absent because when we last checked the listing, the buy box was offering a used unit rather than a new one. We do not send readers to a used-only listing as a ranked pick. If that changes it belongs around second or third here.
The Qrevo Curv, Qrevo Master and Qrevo S were all covered here and are all now withdrawn from sale. Their spec sheets remain on the site as records, marked as no longer sold and with every buy link removed. See model spec sheets if you are researching a machine you already own.
Which Roborock for which house
A normal house with normal floors and a budget - the Q7 M5+. It self-empties, publishes a climb height, fits under a 99mm gap, and has an anti-tangle main and side brush. It is the most documented cheap robot in this range by a distance.
Thick thresholds between rooms - the Qrevo CurvX. The 40mm double-layer figure is the highest Roborock states, and threshold height is the specification that decides whether a room gets cleaned at all. Cross-check it in our threshold table.
Low furniture - the CurvX or the Saros 10R, both at 80mm. That is the flattest body Roborock publishes and it is the difference between clearing a couch and bouncing off it. See under-furniture clearance.
No cameras in the house - the Saros 10R. Its StarSight system is the one Roborock describes without a camera-based obstacle step, which matters to some buyers more than any figure on this page.
A small flat and a minimum spend - the Q7 M5. It is the cheapest machine on this entire site that publishes a real suction figure and a named anti-tangle brush, and you empty the bin yourself.
Mopping as the main job - the CurvX at 17mm of mop lift, the highest Roborock publishes. Our mop lift table shows why that number decides whether a mop combo can be trusted near carpet.
Questions people actually ask
+ Which Roborock has the strongest suction?
The Qrevo CurvX and the Saros 10R are tied at a stated 22,000 Pa, the highest figure Roborock publishes. Because they are identical on that row, suction is not the reason to choose between them - the CurvX publishes a 40mm climb height and the Saros 10R publishes none.
+ Is the Q7 M5+ worth it over the Q7 M5?
They post the same 10,000 Pa suction and the same named anti-tangle main brush, so you are not paying for a better vacuum. You are paying for an auto-empty dock stated at up to seven weeks, a published 20mm climb height and a published 99mm body height. If emptying a bin by hand every few runs would stop you using the robot, that is the upgrade.
+ Why does the mid-range Roborock publish the least?
We do not know, and we will not guess at a motive. What we can state is the pattern: the QV 35A and Qrevo Curv S5X publish a suction figure and a dock description and then stop, while both the flagships above them and the Q7 M5+ below them publish a climb height, and the flagships also publish mop lift and body height.
+ Can I compare Roborock's Pa figures to Dreame's or eufy's?
Only loosely. There is no shared standard for measuring suction, so each maker publishes a number from its own rig. Within this page all seven figures come from the same method and rank honestly against each other. Across brands, treat a Pa figure as a rough tier rather than a score - our Dreame vs Roborock comparison sticks to millimeters for exactly this reason.
+ Does any Roborock climb stairs?
No, and neither does any other robot vacuum sold today. The climb figures on this page refer to thresholds and door strips - a 40mm double-layer rating means a 4cm obstacle, not a step. See no robot vacuum climbs stairs.
