Roborock Qrevo Curv 2 Flow
The Qrevo Curv 2 Flow is the machine that made us look at mopping mechanics rather than mop temperature. It scores 9.0 overall - 8 for cleaning, 9 for navigation, 10 for autonomy - and that autonomy 10 is rare. Most robots mop with spinning pads and wash them at the dock afterwards, which means that between washes the pad is spreading whatever it has already picked up. This one uses a roller that rinses in real time as it runs, so the surface touching your floor is being cleaned continuously. It lists at $999.99, sells near $900, and has traded as low as $850.
Roborock
Qrevo Curv 2 Flow
A roller mop that washes itself while it cleans

Typical price
$900
Strengths
- excellent Autonomy (10/10) — omni
- excellent Navigation (9/10) — Reactive AI, 200+ obstacle types
Habilytics Score
20,000 Pa is solid rather than class-leading - an 8, where the flagships take 10.
Reactive AI recognising 200+ obstacle types, day or night: a strong 9.
A real-time self-cleaning roller mop is the only thing that earns a perfect 10 here.

Why the roller mop earns a perfect autonomy score
Autonomy in our engine measures how much of the machine's own upkeep it handles without you. Most premium robots score 9: the dock empties the dustbin, refills the clean-water tank, and washes the mop after the run. That is genuinely hands-free and it is what almost every omni station here does.
The 10 goes to a different mechanism. A spinning-pad mop is washed at the end of the job, which means that during the job it is getting progressively dirtier and redistributing what it has collected. A roller mop with real-time self-cleaning scrapes and rinses continuously as it turns, so the part touching your floor stays comparatively clean from the first room to the last.
Roborock calls the implementation SpiraFlow. The dock still does the rest - dust self-emptying, water refilling, a 167F mop wash and a 131F hot-air dry at the end.
Only two machines in this catalog earn the autonomy 10 this way: this one and the eufy C28. It is the single most meaningful difference between this machine and the more expensive flagships, and it runs in its favour.
Where it does not lead: raw suction
Cleaning scores 8, and that is the honest ceiling here. At 20,000 Pa it sits below the Dreame X60 Max Ultra's 35,000, the Roborock Saros 20's 36,000, and the MOVA V50 Ultra's 24,000.
How much that matters depends on your floors. On hard flooring, 20,000 Pa is comfortably enough - the suction figure stops being the binding constraint well before that number. Where it shows is deep-pile carpet and rugs, where the robot has to pull debris up out of fibres rather than off a flat surface. If most of your home is carpeted, the flagship suction tier is worth paying for and this is not the machine.
There is a second thing worth flagging honestly: independent reviewers who have tested this machine have been more positive about its vacuuming than its mopping. Our engine reads published specs, so it scores the roller mechanism on what it is designed to do, not on measured wet-cleaning results. That is a real limit of spec-scoring, and it cuts against this machine specifically - so weigh it before buying purely on the autonomy 10.
Zero-tangle, certified rather than claimed
Hair wrapping the brush roll is the failure mode that quietly kills robot vacuums in homes with pets or long-haired occupants. Almost every manufacturer now claims to have solved it.
This listing goes further than a claim: it states a dual zero-tangle system with a 0 percent hair entanglement rate certified by SGS, an independent testing body. A third-party certification is not proof it will never tangle in your particular home, but it is a materially stronger statement than an unverified marketing line, and it is worth more than the same claim made without one.
The practical value is time you do not spend. A tangled brush roll means flipping the robot, cutting hair out with scissors, and doing it again a fortnight later. On a machine sold on being hands-free, that chore is the thing most likely to break the promise.
The price is where it makes its case
It lists at $999.99, sells around $900, and has been seen at $850.
Against the flagship tier, the argument is straightforward. The Dreame X60 Max Ultra and the Roborock Saros 20 both score 9.7 and both cost around $1,600. This scores 9.0 for roughly $700 less. What you give up is suction - 20,000 Pa against 35,000 - and, on the Dreame, the slim body. What you gain is the autonomy point neither flagship has, because both wash spinning pads rather than running a self-cleaning roller.
That is an unusually clean trade to reason about. If your home is mostly hard floors and mopping quality is what you care about, this is the better machine and it is cheaper. If your home is mostly carpet, the flagships are worth their premium and this is not.
Within its own score band, the Ecovacs Deebot X11 OmniCyclone and X9 Pro Omni also reach 9.0, at $1,300 and $1,000. This is the cheapest route to a 9.0 here, and the only one of the three with a real-time self-cleaning roller.
Who it's for / who it's not
Who it's for
- Your home is mostly hard flooring and mopping quality matters more than carpet suction.
- You want the mop surface staying clean during the run, not just washed at the end of it.
- Pets or long hair make brush tangling your recurring chore - this one is SGS-certified against it.
- You want a 9.0 machine without paying flagship money.
Who it's not for
- Most of your home is deep-pile carpet - 20,000 Pa is below the flagship tier where that matters.
- You want the strongest suction available; three machines here state considerably more.
- You are buying primarily on measured mopping results - reviewers rate its vacuuming above its mopping.
Alternatives in our catalog
eufy Omni C28 — $700
The other roller-mop autonomy 10 in this catalog, at about $700 - cheaper, with less suction at 15,000 Pa.
Head-to-head comparisonDreame X60 Max Ultra Complete — $1600
Scores 9.7 for around $1,600. Far more suction and a 3.13-inch body, but washes a spinning mop rather than running a self-cleaning roller.
See how it ranks against the rest
We score every robot vacuum in our catalog on the specs that matter.
Best robot vacuums of 2026This 9.0 comes from the machine's Amazon specifications, each researched and verified before the engine reads them. It weighs advertised suction, stated navigation technology and dock automation across the 36 robot vacuums we track. The 20,000 Pa figure sets cleaning at 8, reactive AI over 200+ obstacle types sets navigation at 9, and the real-time self-cleaning roller mop is what takes autonomy to a perfect 10. Note the limit: spec-scoring cannot measure wet-cleaning results, and independent testers rate this machine's vacuuming above its mopping. Affiliate links never move a score.
