Roborock now also mops with a roller: Roborock Qrevo Curv 2 Flow review
Wiping roller debut.
The Qrevo Curv 2 Flow is the first Roborock robot vacuum with a mopping roller. Our Roborock Qrevo Curv 2 Flow test reveals whether it can wipe the floor with the existing competition and what else it can do.Marcus Schwarten (translated by DeepL / Marcus Schwarten) Published 🇩🇪
Roborock Qrevo Curv 2 Flow test conclusion: We had expected a little more...
Roborock uses the mopping roller for the first time with the Qrevo Curv 2 Flow, but falls short of expectations in terms of mopping performance in the test. The Roborock Qrevo Curv 2 Flow also performed solidly in many other areas in the test, but not really convincingly.
This is largely due to the features, some of which seem a little "old-fashioned". Of course, it is also important to keep the price in mind here, although we would have expected a little more for just under $1.000 MSRP.
Overall, Roborock's mop roller debut Qrevo Curv 2 Flow is a solid robot hoover, although it didn't provide many really convincing purchase arguments in the test. There is still a lot of room for improvement for other Roborock robot hoovers. We would like to see this technology in one of the manufacturer's flagship models in the near future, but please in an improved form.

After we recently tested the Roborock Qrevo Curv 2 Pro, at CES 2026 followed the next new addition to the Qrevo series from Roborock. It goes by the name of Roborock Qrevo Curv 2 Flow and sounds very similar to the IFA innovation.
However, there is one big difference! The Qrevo Curv 2 Flow is the first robotic vacuum cleaner from Roborock to use a roller for mopping. This is available from various competitors such as Dreame and Ecovacs for some time now and have mostly made a good impression there. Our Roborock Qrevo Curv 2 Flow review clarifies whether this also applies to Roborock's mopping roller debut.

Equipment: Wiping roller is the highlight
Let's start with the flagship of the Roborock Qrevo Curv 2 Flow: the mop roller. Roborock calls the roller mop SpiraFlow. As with other manufacturers, it is constantly rinsed with fresh water and freed from dirty water. Compared to some other models, however, the roller, which rotates at 220 revolutions per minute, is quite wide at 27 cm. This ensures a particularly wide mopping area. In addition, the roller can extend out of the side of the housing for virtually borderless mopping.
The SpiraFlow roller mop can be raised by 15 mm. If necessary, i.e. when cleaning carpets, a protective screen can also be moved in front of the fringed mop to avoid wetting the carpet. We already know this from the Dreame Aqua10 Ultra Roller.
This brings us to carpet cleaning and the rest of the features. The suction power is 20,000 Pa. That's a fifth less than the new Qrevo Curv 2 Pro, which is also better equipped in some other areas than the Qrevo Curv 2 Flow.
This applies to the navigation technology, for example. Although both models rely on LiDAR, the laser tower on the Flow is rigid and therefore not retractable. This is not the only reason why it is significantly higher at 11.9 mm, which makes cleaning under furniture more difficult. Neither of the two side brushes can be extended for brimless sweeping. In addition, the main brush is divided into two parts to prevent hair tangling, which worked reliably in the test (as with other models from the manufacturer).
The Roborock Qrevo Curv 2 Flow is supplied with the series' familiar round cleaning station. The multifunctional dock washes the roller mop with 75°C hot water and then dries it with 55°C tempered air. Of course, a dust extraction system into a dust bag is also on board, but once again there is no detergent dispenser. The scope of delivery is also minimalist, comprising only the power cable and a quick start guide.
Setup and app: one thing is missing
Before floor cleaning can begin, the usual connection between the robot, Wi-Fi network and app must first be established. All you have to do is scan the QR code under the magnetic cover. The connection to the home Wi-Fi network is then established before continuing with the obligatory mapping run.
The Qrevo Curv 2 Flow reliably scanned its surroundings and created a virtual map within a few minutes. This was already quite good in terms of spatial distribution. With a little reworking, including optional exclusion zones, the setup was completed within around 10 to 15 minutes.
As usual, there are many options available for the cleaning settings, which we already know from the Qrevo Curv 2 Pro and other Roborock models. However, we did miss a wipe-only mode. This is not offered, which in our opinion would make sense for a robot vacuum with a focus on mopping performance. Instead, in addition to the individual adjustment and the "AI SmartPlan" with automatic AI adjustment, the Qrevo can optionally "Vacuum, then mop", "Vacuum and mop" and "Vacuum". The suction power can be adjusted in four stages and the mopping moisture in 30 stages.
Many options are available in the settings, including individual adjustment of the cleaning behavior and the cleaning station procedure. As you would expect from Roborock, there is also a live video function (after activation) as well as its own voice assistant Rocky for control via voice commands. It mostly listened to what was said, but occasionally felt addressed by conversations during the test period, although no one mentioned the activation word "Hello Rocky".
Navigation and obstacle detection: Solid LiDAR vacuum robot
In terms of navigation, the Qrevo Curv 2 Flow made a confident impression overall, as is also the case with many other LiDAR models from the manufacturer. It navigated systematically through the test environment as far as possible and covered the entire area (as far as possible) in a reasonable amount of time. However, due to its height of almost 12 cm and the non-retractable laser tower, it cleans under significantly fewer cabinets than many other models. So the room coverage is not perfect in the end, but it is good.
Unfortunately, based on our impressions, we cannot say the same about obstacle avoidance. Occasionally there was slight "enemy contact", e.g. with black chair legs and other dark obstacles - despite its own LED illumination of the surroundings. However, while the robot generally avoided larger objects such as a rolled-up USB cable reliably, the obstacle avoidance failed completely when it came to smaller objects such as clamping blocks and a loose shoelace.
We have seen much better results from other models (some of which are considerably more expensive), not just the excellent DJI Romo, but also the brand new Roborock Saros 20. Overall, the Roborock Qrevo Curv 2 Flow does not deliver a really good result in this section of the test, but a solid one overall.
Cleaning performance: falls short of expectations
Roborock is using a mopping roller for the first time in the Qrevo Curv 2 Flow, having previously only models with a vibrating mopping cloth or two rotating mops in the portfolio. At 27 cm, it is quite wide and can also be extended sideways. However, due to the safety distance of a few millimeters between the plastic cover and furniture and the like, mopping is not quite as seamless as with the classic mops with an extendable function.
Thanks to the constantly cleaned roller, the wiping result on the surface is usually better than with the rotating mop discs. These often tend to leave round marks on the floor and spread greasy stains in the surrounding area. However, the mop roller also left some visible streaks when mopping black tiles in our test, presumably due to differently damp areas of the roller.
The cleaning performance itself was okay in the test. However, it is not on a par with top models with a mopping roller, such as the Mova Z60 Ultra Roller. The Qrevo Curv 2 Flow is sufficient for loose and fresh dirt, even if it is greasy. However, more stubborn stains, such as dried-on stains, separate the wheat from the chaff - and thus separate Roborock's mop roller debut from the best challengers. Here, the activated AI detection of particularly dirty areas did not work as reliably as hoped, so that automatic deep cleaning or subsequent cleaning for an improved result did not always take place.
The cleaning performance on thicker carpets was also not quite as good as we have experienced with some other test candidates. On smooth floors and short-pile carpets, however, the Roborock Qrevo Curv 2 Flow's suction power left a good impression in the test, apart from cleaning corners due to the lack of an extendable side brush. Positive: Thanks to the cover, carpet fibers are not contaminated by the mopping unit.
The reprocessing in the station worked reliably, so that the roller-shaped mop was always nice and clean. In addition to the lack of self-cleaning in the station, a negative aspect of the test was that the cleaning station was quite loud at around 45 dB (measured from 1 m away) when the mopping roller was drying. The Roborock Qrevo Curv 2 Flow is much more audible and therefore more noticeable over a few hours than some of its competitors. This should be borne in mind if the station has to be placed directly in the living environment.
Battery life and power consumption: A good 100 m² per battery charge
In our usual battery test, the Roborock Qrevo Curv 2 Flow returned to the station with a battery charge of around 60 percent after cleaning 50 square meters at standard settings. This means that a good 100 square meters can be cleaned with one battery charge. This test candidate can cover significantly more area without long interruptions during recharging than the recently tested Mova Z60 Ultra Roller, which also operates with a mop roller.
If we extrapolate the energy consumption required for 50 square meters of standard cleaning, including charging and the usual preparation in the station, this results in a monthly energy consumption of a good 14 kWh for daily use. This makes the Roborock Qrevo Curv 2 Flow somewhat more energy-hungry than the Qrevo Curv 2 Pro, but is on a par with other robot hoovers with a mopping roller.
