While Dreame and Ecovacs have been on the road with mopping rollers for months, Roborock is only now following suit – but with the promise of having skipped the typical teething troubles. The Qrevo Curv 2 Flow is said to get edges clean and leave no streaks. The SpiraFlow roller is continuously moistened with fresh water during the journey and is then removed internally – the theory is clear: constantly clean mopping instead of an increasingly dirty pad. We put the Roborock Qrevo Curv 2 Flow device through its paces. Here’s what really works – and where Roborock 2026 still has some “homework” to do.

Scope of delivery & assembly: typical Roborock – quickly ready for use
The first impression when unpacking is immediately “okay, this is a system” – robot, station, tanks, all solidly made. The new Curv 2.0 dock design is much rounder and more flowing than the previous angular Roborock stations. Whether this is a visual upgrade is a matter of taste – we personally like the angular version better, and the lack of storage space on the station is also annoying in everyday use.
On opening, everything looks typical Roborock: neatly packaged, lots of foam, clearly sorted – there are no surprises at first.
.
Laid out on the floor, you can quickly see how tightly Roborock holds the scope of delivery.
What’s inside the box:
- Robot
- Docking station (Curv 2.0 design)
- Fresh water tank (station)
- Dirty water tank (station)
- Dust bag (station)
- Power cable
- Operating instructions
.
That’s it. No huge bag of replacement brushes, no test pads, no “bonus bag”, no cleaning agent. Roborock keeps the scope of delivery short – but what is included is exactly what you need to get started. If you want to use detergent, you have to buy it separately and add it manually to the fresh water. Roborock sells its own Floor Cleaning Solution, but that doesn’t change the fact that many in the price range would expect something like this.
The set-up was pleasantly unspectacular. Get the fresh water tank from the station, fill with water, set up the station, dock the robot – it was done in a few minutes. That’s exactly how it has to be, because nobody wants to spend an hour sorting parts for a premium robot.
App & setup: quick to set up, without a menu maze
For us, the setup was exactly what we wanted – add the robot, connect the Wi-Fi, done. No cryptic steps, no “now please press two buttons simultaneously for 12 seconds” number. You can just tell that Roborock has been doing app setup for years.
The app is also where the real convenience lies. SmartPlan 3.0 recognizes room types, automatically adjusts the suction power and water volume and remembers your habits – in other words, the robot learns over time when and how intensively which room needs to be cleaned. There are also the typical Roborock features such as map management (up to 4 floors can be saved), no-go zones, schedules and, of course, all the station options for washing and drying.
In addition to Alexa, Google Assistant and Siri, there is also the in-house voice assistant “Rocky”. With “Hello Rocky”, the robot also starts offline – this actually works without an internet connection, which is not the case with the others. For smart home fans, Matter support is also included, which makes integration into existing systems much easier. If you have pets, you get automatic pet detection, real-time video calls and photo snapshots – all opt-in via camera. The robot can track pets and avoids sleeping dogs or cats.
SpiraFlow mop roller: Roborck’s answer to the roller competition
The central idea of the mopping roller is simple, but relevant in everyday life – while the robot is mopping, the roller is continuously moistened with clean water, picks up dirt and is removed again internally. This means you don’t have the classic “mop gets grayer and grayer” problem as much as with simple pad systems.
The roller is 270 mm wide, rotates at up to 220 rpm according to the manufacturer and applies 15 N of pressure to the floor – that’s 2.5 times more pressure than its predecessor, the Qrevo Curv. Eight nozzles distribute the fresh water evenly across the roller, while an internal scraper directs the dirty water into a separate tank. In practice, this actually worked cleanly for us – the roll came back clean after cleaning in the station, without any odors or visible residues.
The roller moves up to 10 mm to the right of walls and furniture. This is not perfect, but significantly better than many early roller models, which often left streaks on edges. If you want to service the roller yourself from time to time, it’s easy to do – take the roller out, clean the scraper area and you’re done. No fiddling required.
.
On carpets, the roller lifts up to 15 mm, and an additional roller shield extends to minimize direct contact. This works well with flat carpets, but with very high pile it becomes more difficult – but this is not a Roborock problem, but a general roller issue. At some point, you can no longer lift away what is physically close to the floor.
Vacuuming: strong base, also convincing with fluff and hair
Roborock states 20,000 Pa – figures are always difficult with robots because they vary depending on the mode, floor and brush. The new Saros models are now at 35,000 Pa, so the Curv 2 Flow is not top class here. What counts for us is the behavior in real use. And it really delivered when vacuuming.
We spread a mixture of dry rice, herbs de Provence (due to different particle sizes) and crispbread crumbs on our flat carpet. The robot went over some areas two or three times, but stubbornly kept going until everything was gone. That’s exactly how it should be – better a few more passes than giving up half-heartedly.
We were particularly impressed by the DuoDivide Anti-Tangle System with the two-part main brush. Lint, including dog hair, was picked up very cleanly without us having to pull a ball of wool out of the brush afterwards. This is exactly the point for many households – it is not enough for a robot to be able to “dust” if it then requires regular maintenance when it comes to hair. Incidentally, the two side brushes can be raised if necessary, for example when the robot detects liquids.
Where it gets a little more problematic: It sometimes pushed along (high) pile runners instead of maneuvering cleanly over them. It also doesn’t reach corners perfectly because the side brushes can’t extend. Not a disaster, but something you should know in advance.
Mopping: the roller really makes a difference
When it came to mopping, we wanted to know whether the roller really makes more of a difference than classic pads. And yes, the difference is noticeable. The robot gets rid of normal everyday dirt such as footprints, light stains or spilled liquids very well. The roller actively picks up the dirt instead of just spreading it around – even if the home hasn’t been cleaned for a while.
It performed well in our test with spilled coffee and olive oil (small test quantities of each). The coffee was no problem, and it also picked up the olive oil properly without smearing everything. The SmartPlan AI mode helps here because the robot runs over it several times when it detects dirt. The result was clean for us – no greasy film, no sticking. This is a real advantage over simple pad systems, especially with oily items.
.
What is positive is that the roller actually comes back clean after cleaning in the station. No discoloration, no smell. This is a problem with many roller systems, but Roborock seems to have done its homework here. The roller moves up to 10 mm to the right of edges, which is significantly better than many early roller models, which often left streaks.
DirTect AI dirt detection: useful extra, but no magic bullet
The Curv 2 Flow works with DirTect KI – a system that distinguishes between dry and wet dirt and then reacts accordingly. In the case of heavy dust, it increases the suction power; in the case of liquids, it switches to pure mopping mode and raises the brushes so that nothing is spread. The idea is good because the robot doesn’t stubbornly run its standard program, but adapts itself.
In practice, this works to varying degrees. In the case of clearly recognizable dirt, it reacts in a comprehensible way – runs over it several times and increases the suction power. Depending on the light and type of dirt, however, the detection is sometimes very accurate and sometimes more like a normal program. The result is still clean because the basic cleaning is right.
For us, this is not a major point of criticism. The dirt detection is a nice extra that sometimes really helps and sometimes just runs in the background. What’s more important is that the robot cleans properly even without perfect AI recognition – and it does. Anyone hoping for “automatically recognizes every crumb and adapts perfectly” will be disappointed. If you have realistic expectations, you will get a system that works.
Station & maintenance: convenient, but not perfect
The station does what you would expect – vacuum, wash the roll, dry. According to the manufacturer, the roll is washed with water at up to 75 °C and then dried with 55 °C warm air. The result in practice is convincing because the roll comes out of the station clean and odor-free after cleaning – which is ultimately more important than the exact temperature on the paper.
What is missing: An automatic detergent dispenser, as we know it from some high-end stations. Here, the detergent has to be poured manually into the fresh water tank. In addition, the station does not clean itself – the wash tray should be rinsed manually under running water from time to time, otherwise deposits can build up.
As with most robots, the drying process uses warm air and is therefore audible – but not exceptionally loud or long. If you need absolute silence immediately after cleaning, you can adjust the settings in the app. All in all, the station works very well, but is not quite as maintenance-free as premium models that clean their own washing tray.
Navigation, height & wheelchair accessibility: the LiDAR problem
The navigation itself is typical Roborock – clean, organized, comprehensible. Maps are correct, lines fit, the system works reliably. No surprises, no quirks.
.
The real problem is the height – for a reason that could have been solved. The robot comes to 11.9 cm because Roborock has installed a fixed LiDAR tower here. This cannot be retracted, although this has long been standard for competitors with rollers. Dreame, Ecovacs and others either have retractable LiDAR towers on their scooter models or work completely without LiDAR with camera navigation. Roborock takes the “classic laser tower, always on top” approach here – which unnecessarily increases the height, even though the roller alone takes up space.
In practical terms, this means: coffee tables with low crossbars, flat sofas, certain bed frames – all furniture that the device cannot get under. This is not a software problem, but purely a design issue. If you have a lot of low furniture, you should measure it beforehand, otherwise there will be large “no-go zones” that you didn’t want.
With carpets, it works well in the normal range, especially on flat carpets. High pile is more difficult, but that’s the case with all roller models. What is really annoying is that the side brushes are fixed and cannot be extended. Extendable side brushes or FlexiArm systems are available on many premium models – even on Roborock itself in other series. This has been omitted here, and this is directly noticeable in corners and along edges. The perfect 90-degree corner doesn’t happen because the reach is simply lacking. This is actually a feature that has long been standard.
Conclusion: good wiping performance, questionable design decisions
The Roborock Qrevo Curv 2 Flow is Roborock’s answer to the scooter trend – and it’s late. Dreame, Ecovacs and others have had roller models in their range for longer, so some solutions from the competition are already more mature. What Roborock delivers here is still not a bad device – but one with clear compromises.
The SpiraFlow mopping roller works well. It cleans itself during the journey, comes back clean from the station and wipes noticeably better than rotating pads. The system is convincing when it comes to dried stains, footprints and normal everyday dirt. It also delivers a solid performance when vacuuming – 20,000 Pa is mid-range, but is easily enough for hair, fluff and hard floors. The station works reliably, the navigation is typical Roborock, i.e. without any quirks.
What is really annoying: The height of 11.9 cm could have been avoided. Roborock uses a fixed LiDAR tower that cannot be retracted – even though the competition has long been using retractable towers or camera navigation for roller models. The result is an unnecessarily high robot that cannot get under many pieces of furniture. In addition, there are no extendable side brushes, although this has long been standard on premium robots (including Roborock itself in other series). As a result, corner cleaning remains mediocre.
If you have a lot of hard floors, mopping performance is important and your furniture is not extremely low, the Curv 2 Flow is a good choice. However, if you have a lot of low furniture, value perfect corner cleaning or mainly want to clean high-pile carpets, there are better options – some even from Roborock’s own range.

The Qrevo Curv 2 Flow impresses with its SpiraFlow mopping roller and solid suction power. The station works reliably and the app is great. However, the height of 11.9 cm due to the fixed LiDAR tower and the lack of extendable side brushes are design decisions that are no longer up to date in 2026.
