The Roborock Qrevo Curv 2 Pro is a powerful vacuum — it's a shame its mopping falls flat

If you're after a best robot vacuum, it stands to reason that the impossibly-named Roborock Qrevo Curv 2 Pro would be a small step up from its recent predecessor, the Qrevo Curv 2 Flow. However, it’s practically a whole different beast, with more features that separate than unite the two.

In my Qrevo Curv 2 Flow review, I was a huge fan of its excellent mopping thanks to its extendable roller mop, though there were streaking issues. When it comes to the Pro model, a huge 25,000 pa of suction, circular mopping pads, a single extending brush arm, a much slimmer chassis, and a retractable sensor are a few of the things it does differently.

But which one delivers better cleaning, and which one is best for you? I’ll be delving into this newest Pro model while providing a direct comparison with its older brother in this review.

Roborock Qrevo Curv 2 Pro review: Price and availability

The Roborock Qrevo Curv 2 Pro is currently available in the UK and Europe from uk.roborock.com for £999.

Unfortunately, a launch date for the US market is still pending, but it is anticipated to be scheduled for later in 2026.

Roborock Qrevo Curv 2 Pro review: Design

The dock of the Curv 2 Pro is virtually identical to that of the Curv 2 Flow, save for the dual mop tray. It’s the same Stormtrooper-white helmet design that, at 45cm wide, isn’t exactly the slimmest base station around, so ensure there’s plenty of room in your chosen install location. Note that there’s no detergent tank, which is in line with the Curv 2 Flow. It’s not a major inconvenience, but you need to take the extra step of measuring out the right detergent every time.

The robot itself is where the differences become more apparent. Notably, the Pro’s vacuum unit is much thinner at 8cm over the Flow’s 12cm, which is an impressive slice off the top. Also significant is the replacement of the roller mop with dual spinning, detachable mopheads, while there’s also a solitary brush arm instead of the traditional two. You may also notice the RetractSense LIDAR unit positioned at the top towards the back of the unit, which retracts down and lets the robot slip under narrow furniture. There’s also a set of sensors on the front and side, which help detect rogue objects in its way. Finally, you’ll find the familiar dual brush system in the suction port, which helps with hair detangling.

The robot does look attractively compact, particularly with its silver-coloured LIDAR unit creating a sleeker-looking machine. Admittedly, the glossy plastic is a magnet for hair and dust, but it’s one of the better-looking robovacs all the same.

Eagle-eyed readers may have already spotted that the Pro sports one of the highest suction powers in its class, with a generous 25,000pa of force. And while some premium units break 30,000pa, not that many new units offer 25K at this price range.

Another big selling point of the Curv 2 Pro is its AdaptiLift chassis, which provides a lift of up to 4cm for optimal thick carpet and rug cleaning, as well as easy traversal of girthy thresholds. Perfect for getting over those awkward U-shaped legs of that Ikea lounger.

Roborock Qrevo Curv 2 Pro review: Performance and test results

We use standardized tests to objectively measure how robot vacs perform against their many peers. They include sprinkling 20g of Cheerios, 20g of kitty litter, and 5g of pet hair on a laminated hardwood floor and low-pile carpet to determine how much the vacuum sucks up and what percentage remains. On top of that, I’ve been using the Curv 2 Pro regularly for nearly two weeks.

In these tests, the Pro acquitted itself very admirably, with scores in the high 90s when hoovering Cheerios and cat litter. It fared slightly less well with cat hair but still managed a very respectable average of 87%. It was during these tests that the lack of a second brush arm hindered its results — several clumps got stuck in the wheel opposite the brush arm, preventing it from securing a higher score. Though the unit has fairly comprehensive coverage, there may be times when the odd bit of dirt is deflected away, and a second brush would have helped minimize that.

Mop performance

The time came for my trusty ketchup test, where I drizzled Heinz’s finest in a large S shape across my kitchen floor. While the Pro happily tackled the red splash with some gusto, I was disappointed that it left a telltale series of small but perceptible sticky smears from the spinning mops.

I’ve always been of the opinion that roller mops are superior to spinning pads because they can clean themselves on the go while being able to apply greater downward pressure. The Pro’s mopping performance gave me no reason to adjust that mindset. I was a big fan of the Flow’s roller mop, which extends out for better edge cleaning. I guess Roborock opted for this route to maintain a slimmer profile in the Pro, but as someone with a fairly large hardwood kitchen, I can’t help but feel a little disappointed that the mop didn’t live up to the excellent vacuum performance.

On top of that, I noticed that when the mop extends, a couple of inches of space would open up between the spinning mops that were not cleaned. So while general mopping is fine, I could tell there were small areas of inconsistent wiping, even though both the extendable mop and brush arm can attack edges and awkward nooks enthusiastically.

Another puzzling omission was the lack of the left spinning brush. Sure, the large FlexiArm right-side brush, in tandem with the DuoDivide main brushes, generally works well, but there’s still a left channel that fails to pull dirt into the suction area. This was evident during my testing, where telltale clumps of cat hair got clogged in the Pro’s left wheel.

Given the LIDAR tower at the top and rear of the unit, I also wanted to test its object avoidance, which was generally solid for taller items, but when I started using smaller objects, like a compact mirror brush or small toy car, the Pro would absentmindedly clatter into them. There’s a reason why most LIDAR units are positioned near the front third of the robot, but it’s puzzling why the front camera sensor doesn’t kick in effectively for hazards below the tower’s sensor range.

It’s not all bad, however. Roborock’s trademark navigation is still excellent, as the Pro effortlessly glides under couches and beds to bust dust, and its adaptive chassis made light work of most thresholds and furniture. One time, it effortlessly inserted itself between two chair legs that were barely wider than its chassis. The way it moves smoothly and gracefully is indicative that Roborock leads the way in robovac navigation.

I also felt that its vacuum performance on thicker rugs and carpets was excellent, with its self-raising chassis combined with strong suction able to pick up even the most packed-in debris. Fabrics under the feet suddenly looked much cleaner and felt neater to stand on. Also, robovac owners know it’s common for some carpeted surfaces to feel a little damp as the mop travels with the vacuum. However, with the Pro, the mop pads are left behind until the hard surfaces are vacuumed, which is less gimmicky and more useful than I realized. It helps prevent smearing and cross-contamination on fabric surfaces, and with its 100-degree hot water wash, the mops have minimal odor when they’re in play.

Roborock Qrevo Curv 2 Pro review: App

Another strong canon in Roborock’s arsenal is its feature-packed app. It’s by far the most comprehensive I’ve used, with sliders for desired suction power, water flow, cleaning count, and route density. There are also cleaning settings for the cleaning pattern and sequence you want.

Plus, there’s the usual room selection and setting no-go areas that most vac apps have. Some options, like editing and creating new maps, can be a little buried within its menus, but for the most part, Roborock’s app is clean, clear, and impressively customizable.

Roborock Qrevo Curv 2 Pro: Verdict

For me, the Roborock Qrevo Curv 2 Pro (seriously, with that name, Roborock?) is a robovac of two halves.

On the one hand, the mopping experience falls quite short of my expectations, with slightly inconsistent coverage and a lack of mopping power when it comes to thicker or persistent stains. While it’s perhaps rare that it’s expected to tackle these stains consistently, it does seem like the Qrevo Curv 2 Pro has sacrificed mopping power for a slimmer chassis.

On the other hand, you have a very capable vacuum with impressive suction ability, and even without that second brush arm, which would have minimized stray debris further, it excels on hardwood floors and fabrics alike.

Don’t think of the Pro as the upgrade from the Curv, then — both are better and worse at different things. The Qrevo Curv 2 Pro is all about eliminating dirt and debris from homes with mixed surfaces and inconsistent layouts, including thick carpets and rugs, particularly with small gaps under couches, beds, and coffee tables.

Should I buy the Qrevo Curv 2 Pro or the Qrevo Curv 2 Flow?

It largely depends on your home, the composition of your furniture, and what floors you have. What might be more important to you is a machine that can nimbly clean under tight gaps and deftly negotiate awkward thresholds.

They might also have high carpets or need to take care of excessive pet hair. In these cases, the Pro is a worthy household addition, thanks to its excellent suction and thin, adaptive chassis.

But, if you’re after a more balanced robot vacuum that can handle messy kitchen splashes, the Flow might be more suitable. For me, with a larger communal kitchen and kids creating more mess than the cat, I’m going with the Flow.
