Roborock Qrevo Curv 2 Flow review: a roller mop that scrubs as it goes

Roborock Qrevo Curv 2 Flow at a glance

First impressions of the Roborock Qrevo Curv 2 Flow

The Qrevo Curv 2 Flow looks like the Qrevo Curv family at first glance: the same soft, curved dock and a round robot with a LiDAR turret on top.

Turn the robot over, though, and the difference is obvious.

Instead of two spinning mop pads, there is a single wide roller across the back.

That roller is the whole point of this model.

Roborock calls it SpiraFlow, and it's designed to work more like a floor scrubber than a damp cloth.

The Curv 2 Flow keeps the look of the Curv line: a glossy white body and a rounded, domed dock.

Build quality is excellent. Panel gaps are tight, nothing creaks, and the roller assembly sits securely. The glossy top does pick up fingerprints easily.

The bigger design issue is height. At 4.7 inches, it's one of the taller robots on the market. The LiDAR turret doesn't retract, and the roller mechanism needs room inside the body.

It wouldn't fit under several low sideboards and sofas that slimmer models like the Saros 10R (under 3.2 inches) clear easily. If you have low furniture, measure before you buy.

Measure first: hold a tape measure under your sofa, bed and sideboards. You need at least 4.7 inches of clearance, plus a little extra so the robot doesn’t get wedged.

The curved dock is one of the best-looking robot vacuum docks you can buy.

What the Qrevo Curv 2 Flow actually is

The Qrevo Curv 2 Flow is a robot vacuum and roller mop with a multifunction dock.

The roller is about 10.6 inches wide and spins at around 220 rpm.

Eight hydration points spread clean water across it, and a built-in scraper pulls dirty water off the roller while the robot moves.

That means the robot isn't dragging a dirty pad around the room between dock visits, which is the main weakness of many pad-based mops.

Suction is rated at 20,000 Pa, up from 18,500 Pa on the original Qrevo Curv.

A DuoDivide split main brush resists hair tangles, and the robot uses PreciSense LiDAR for mapping plus Reactive AI obstacle avoidance with an RGB camera.

There's also a DirTect feature that is meant to spot different types of mess and adjust suction or water flow on the fly.

The dock: what it does for you

The curved dock empties the robot's dustbin into a bag and refills the onboard water tank.

It washes the roller with 167°F water and then dries it with 131°F hot air.

The dock holds a 1-gallon clean water tank and a 0.8-gallon dirty water tank, according to independent testing.

The base is detachable, which makes it easier to clean the washing area.

One feature you might expect at this price is missing: there is no automatic detergent dispenser, so you add floor cleaner to the clean water tank yourself.

The dock measures about 18 × 18 × 18 inches, so it's large but not unusually so. Alongside the 1-gallon clean and 0.8-gallon dirty water tanks, it holds a 2.6-quart dust bag.

After each job, the dock:

• Empties the dustbin
• Washes the roller in 167°F water
• Dries it with 131°F hot air for about three hours
• Refills the robot's water tank
• Cleans its own washing tray

Because you add cleaning solution straight into the clean water tank, some people will count the missing detergent dispenser as a gap. Others prefer it to buying small proprietary cartridges.

Tip: use a low-foaming floor cleaner made for robot mops, such as Roborock’s own solution, and stick to the recommended dose. Regular floor soap can foam up and leave residue in the dock.

Qrevo Curv 2 Flow design and setup

The robot is tall for a 2026 Roborock, at almost 4.7 inches including the LiDAR turret.

That's noticeably taller than the slim Qrevo Edge and Saros models, so check the clearance under your sofa and bed.

Threshold climbing is modest. Measured results range from about 0.4 to 0.8 inches, and there's no lifting chassis, so standard door transitions are fine but tall thresholds will stop it.

Setup runs through the Roborock app: scan the code, fill the water tank, and let the robot map your home.

Reviewers report that the first map takes only a few minutes in an apartment, though mirrors and glass doors can create phantom rooms you'll need to clean up in the app.

Qrevo Curv 2 Flow performance

Mopping with the SpiraFlow roller

The roller presses down with roughly 15 newtons of force, more than twice the pressure of the original Curv's pads.

In independent tests, fresh spills like milk and mayonnaise came up in one pass, while dried sauce needed a second pass.

Because the roller is scraped continuously, it should leave fewer dirty streaks on large floors.

Results do vary by floor: one lab test saw streaks on dark tiles and weaker results on dried-on stains.

In practice, the SpiraFlow system is excellent on fresh messes. It cleaned up these in a single pass:

• Ketchup, mayonnaise, milk and coffee grounds
• Sticky fruit compote
• An olive oil trail tracked across a kitchen

Several owners say it's the first robot mop good enough to replace their manual mopping. Because the roller stays wet, the robot also returns to the dock less often during long jobs.

The system isn't perfect, though:

• Dried-on stains are no easier for it than for good spinning-pad mops. They still take multiple passes.
• Uneven wetting: with eight nozzles across a 10.6-inch roller, faint dry lines can show on dark tiles. Turning the water flow up in the app largely fixes this, and on light floors you may never notice it.
• Stain detection is less reliable than on other Roborocks, so the robot doesn't always focus on dirty spots by itself.
• There's no full mop-only mode. Mop-only cleaning exists only for spot and zone cleaning, which is a dealbreaker for some buyers.

Tip: seeing faint dry lines on dark tiles? Raise the water flow a few steps for those rooms in the app. With 30 levels, you can fine-tune it per room.

Edges and corners

The roller can shift sideways toward the wall, but edge coverage is the most debated part of this robot.

Testers saw it get within about half an inch of walls on some runs and leave wider gaps on others.

Corners are a known weak spot because the front brushes don't extend outward.

There's no extending side-brush arm like the one on the original Curv, so 90° corners get missed and usually need a manual touch-up.

Good to know: in kitchens and bathrooms with lots of 90° corners, plan on a quick manual wipe of the corners every so often. The roller simply can’t reach into them.

Vacuuming and carpets

With 20,000 Pa of suction, the Curv 2 Flow handles dust, crumbs and hair well on hard floors and short-pile rugs.

It is weaker on thick carpet, which is typical for robots in this class.

When it detects carpet, the mop lifts up to 0.6 inches and a Roller Shield slides around the roller to keep rugs dry.

On hard floors, it picks up rice, crumbs and cat litter reliably. The two lifting side brushes help sweep debris into the main brush, and the DuoDivide split main brush resists tangling well, with almost no hair wrap over weeks of use.

Carpet is a different story. High-pile rugs are left with crumbs behind, especially along edges and in corners. The most critical lab testing found pet hair pickup from carpet poor, because the brush doesn't agitate carpet fibers deeply enough.

Owners of heavy-shedding dogs are divided. Some are happy with it, while one owner with two German Shepherds called it the most hands-on robot they'd owned.

Pet owners: if most of your floors are rugs and you have a heavy shedder, this isn’t the strongest choice. Look at the alternatives below first.

Carpet protection, on the other hand, works very well. When the robot detects carpet, the roller lifts 0.6 inches and the shield slides over it, and even high-pile rugs stayed dry.

A few other weaknesses: the internal dustbin fills faster than its size suggests, very fine debris can spill back out, the dust bag doesn't seat perfectly in some docks, and pet hair can clump in the emptying chute.

Navigation and obstacle avoidance

LiDAR navigation is reliable and systematic, with good room coverage.

Obstacle avoidance uses Reactive AI with an RGB camera. It works well on hard floors but is noticeably less reliable on carpet.

A quick floor check before a run is still a good habit with this model.

It ran over flat white cables, got caught on tote bag straps and rug tassels, and didn't always avoid pet waste.

Threshold climbing is modest at about 0.4–0.8 inches, with no lifting chassis. Standard door transitions are fine, but tall thresholds will stop it.

At almost 4.7 inches tall, the robot fits under fewer cabinets than slimmer Roborock models.

How loud is the Qrevo Curv 2 Flow?

Roborock doesn't lead with a noise figure for this model.

Independent testing measured around 45 dB at about three feet while the dock dried the roller, which is quiet but noticeable when it runs for a few hours.

As with any self-emptying dock, the dust evacuation is the loudest moment, but it only lasts a few seconds.

Tip: schedule cleaning for when you’re out or early in the day, so the roughly three-hour drying cycle is finished by the evening.

Maintenance: what you still have to do

The dock handles most daily care, but a few jobs are still yours.

Routine maintenance is mostly simple: the bin, roller and scraper slide out easily, and voice prompts confirm you've reinstalled them correctly.

Some jobs are more involved. The side brushes need a screwdriver to remove, the mop cover is held by small screws that are easy to lose, and the roller can't go in the washing machine.

Tip: keep a small screwdriver and a cup nearby when you service the mop cover, so the tiny screws don’t go missing.

Consumables include dust bags, filters, side brushes, the main brush, the roller and cleaning solution. Costs are reasonable because Roborock's parts ecosystem is well established.

The standard warranty is 12 months in some regions, and a few owners report frustrating experiences with customer service.

The Roborock app

The Roborock app offers multi-floor maps, room splitting, no-go zones, carpet settings and scheduling.

Carpet handling can be set with one tap, and the robot switches suction and mop lift automatically.

One odd omission is a full mop-only mode: mop-only cleaning is available only for spot and zone cleaning.

Voice control works with Alexa, Google Home and Siri once rooms are named, and Matter support makes smart home integration easier.

Tip: name your rooms in the app before you link Alexa, Google Home or Siri. Then commands like “clean the kitchen” work straight away.

The app remains a highlight. It offers room-by-room suction and water settings with 30 levels of water flow, carpet mapping by shape and pile type, no-go zones and schedules, plus a live camera view and a pet patrol mode.

Battery life is good, at roughly 140–150 minutes of runtime, which is enough for most apartments in one go. Larger homes trigger a recharge break, and recharging takes close to three hours.

Is the Roborock Qrevo Curv 2 Flow worth the money?

The Qrevo Curv 2 Flow lists at $999.99, but it often sells for around $700–$850 in the US.

That puts it against Roborock's own spinning-pad flagships.

If your home is mostly open hard floor and mopping matters most to you, the roller is a real upgrade: you get top-tier mopping without paying flagship prices.

If you have lots of corners, low furniture or thick carpet, a spinning-pad model with an extending mop arm may suit you better.

Price tip: the $999.99 list price is rarely what people pay. It regularly sells for around $700–$850, so wait for a deal rather than paying full price.

Prices change often, so check the current price on Amazon before you buy.

Qrevo Curv 2 Flow vs Qrevo Curv vs Qrevo 2 Pro

Here is how the roller-mop Curv 2 Flow compares with Roborock's spinning-pad models.

Best Roborock Qrevo Curv 2 Flow alternatives

If corners matter more than raw scrubbing, a spinning-pad model with an extending mop is the safer pick.

The Roborock Qrevo 2 Pro brings FlexiArm edge mopping and a hot-wash dock for much less money.

The original Roborock Qrevo Curv uses spinning pads with a FlexiArm and a lifting chassis.

Both the original Curv and the Qrevo Curv X are better all-rounders than the Curv 2 Flow, with an extending side brush and better threshold climbing. The Saros 10R is slimmer and stronger overall if your budget allows, and the Dreame X60 Max Ultra Complete is the pick for tall thresholds.

How I tested and scored the Roborock Qrevo Curv 2 Flow

I scored four areas, and each gets its own subscore.

• Mopping (8.6): everyday dirt, dried stains, streaks and edge coverage.
• Vacuuming (8.0): pickup on hard floors, rugs and carpet, including pet hair.
• Dock and upkeep (8.4): how much of the maintenance the dock takes over, and what is left for you.
• Navigation (7.6): mapping accuracy, thresholds and how it handles obstacles.

The overall score is an editorial rating. I also checked Roborock's published specifications and compared them with independent test results and other Roborock models.
