The Roborock Qrevo Curv 2 Flow is a premium robot vacuum and mop that marks Roborock's first attempt at a roller mop design, replacing the spinning mop pads found on its predecessor, the Roborock Qrevo Curv. The roller rinses itself as it works, and the dock performs a deeper clean with hot-water washing and warm-air drying. The chassis lifts up when it detects carpet, and a shield slides into place to cover the roller, preventing the mop from getting carpet fibers wet. For navigation, it uses LiDAR with camera-based obstacle avoidance, and an onboard dirt detection system identifies the type of mess in its path, boosting suction for dry debris or shifting to mopping for wet stains. An anti-tangle brush system on both the main roller and side brushes is designed to minimize hair buildup during cleaning.
Our Verdict
The Roborock Qrevo Curv 2 Flow does a decent job as an everyday cleaner for mixed-surface homes. It handles hard floors well, picking up most everyday debris, and the dock handles routine maintenance automatically, so day-to-day upkeep stays minimal. That said, it doesn't perform as well on carpets, leaving noticeable debris along edges and corners. Obstacle avoidance on carpet is inconsistent enough that you may need to step in occasionally. It's particularly unsuitable for pet owners with carpeting, because it struggles to effectively lift pet hair that's been embedded in carpets.

The Roborock Qrevo Curv 2 Flow is an okay choice for pet owners, though it comes with some notable caveats. It runs quietly enough that it won't startle anxious animals, and the dock handles most maintenance automatically, which helps when dealing with the extra mess pets bring. However, it leaves a lot of pet hair behind on carpets, so if shedding is your main concern, it might not be able to keep up between manual cleanings. It also doesn't consistently avoid pet waste, so there's a real risk of a messy situation if it encounters an accident, especially if carpeting is involved.

The Roborock Qrevo Curv 2 Flow does a good job on hard floors, picking up the majority of everyday debris without scattering much around. You'll find small amounts left behind along edges and in corners, so those spots will still need occasional attention, but you can rely on it to thoroughly clean open floor areas.

The Roborock Qrevo Curv 2 Flow does an adequate job cleaning carpets, picking up most debris from open areas, but it consistently leaves noticeable amounts along baseboards and corners on both low and high-pile carpets. Some debris also gets dragged or scattered rather than collected, so you might have to do manual touch-ups if your home has lots of carpeting.
Leaves some debris behind along edges and in corners.
The Roborock Qrevo Curv 2 Flow does a poor job picking up pet hair from carpet. It leaves a large amount behind after each cleaning pass because the brush roller struggles to agitate the carpet fibers enough to lift the hair. Some hair also gets dragged around rather than being picked up. If you have shedding pets, you'll need to vacuum manually on a regular basis to keep your home fur-free.
Struggles to pick up pet hair from carpet.
Drags some hair around rather than picking it up.
The Roborock Qrevo Curv 2 Flow does an okay job of handling obstacles, though performance varies by surface. On hard floors, it navigates around objects reliably and rarely needs you to intervene. On carpet, however, it bumps into things much more often and will need you to step in occasionally to help out. Its taller body also keeps it from fitting under low-profile furniture, and rugs with tassels can cause it to get stuck. Most importantly for pet owners: it doesn't consistently avoid pet waste, so you should exercise caution if your pets are accident-prone.

Popular Robot Vacuum Comparisons
The Roborock Qrevo Curv 2 Flow is a premium robot vacuum and Roborock's first model to use a roller mop instead of spinning mop pads. This sets it apart from much of the competition, including its predecessor, the Roborock Qrevo Curv. Despite the new mopping mechanism, however, it doesn't actually offer improved stain removal when compared with the original Curv, largely because its stain detection system isn't as successful. There are other robovacs with roller mops that deliver better overall performance, including the Ecovacs DEEBOT X8 PRO OMNI and Dreame Aqua10 Ultra Roller. Though it offers better obstacle avoidance than the original Curv, it's still not a top-in-class performer. Within Roborock's own lineup, the flagship Roborock Saros 10R outperforms it in most areas if you have the budget for it. In the broader market, the Curv 2 Flow holds up reasonably well as an everyday cleaner if you have mostly hard floors, but competitors like the Roborock S8 MaxV Ultra and MOVA P50 Pro Ultra do better when it comes to lifting pet hair and debris from carpets.

The Roborock Qrevo Curv and the Roborock Qrevo Curv 2 Flow are both premium robot vacuum and mop combos, but they have different strengths. The original Curv is the better choice if debris pickup is your main concern, because it outperforms the Curv 2 Flow on both hard floors and carpet. It also features the AdaptiLift system, which lets it cross taller thresholds. The newer model, however, comes equipped with a roller mop that offers better stain removal. It also has a more advanced obstacle avoidance system, so it's a better pick for cluttered homes.
The Roborock Saros 10R and the Roborock Qrevo Curv 2 Flow are both premium robot vacuum and mop combos, but the Saros 10R is the stronger performer across the board. It delivers significantly better hard floor pickup, and its low-profile design lets it reach under low furniture. Obstacle avoidance is also superior because of its StarSight sensor suite. The Curv 2 Flow uses a roller mop that applies more consistent pressure across the floor, which may appeal to those who prioritize daily mopping coverage.
The Dreame X50 Ultra and the Roborock Qrevo Curv 2 Flow are both robot vacuum and mop combos, but they have different strengths. If obstacle avoidance is a priority, the X50 Ultra is the better pick, because it detects and avoids objects far more reliably on both hard floors and carpet. The Curv 2 Flow has the edge when it comes to hard floor debris pickup and stain removal, where its roller mop applies more consistent pressure than the X50's spinning pads. Both models handle carpet similarly, though neither excels at pet hair.
The Ecovacs DEEBOT X8 PRO OMNI and the Roborock Qrevo Curv 2 Flow are both robot vacuums with roller mops, but the X8 PRO OMNI delivers stronger cleaning performance across the board, with better results on hard floors, carpet, pet hair, and stains. The one area where the Curv 2 Flow has the edge is that it can clear taller thresholds, because the X8 PRO OMNI struggles with anything but very low transitions and will turn away rather than attempt to climb them.
Test Results

The Roborock Qrevo Curv 2 Flow feels very well-built, with a noticeably sturdy construction. The bumper and buttons are both responsive and feel solid, and the top cover stays securely in place during operation.
Unfortunately, the glossy top cover is a fingerprint magnet, and the overall aesthetic is noticeably bulkier than its predecessor. The spinning LiDAR turret sits quite high on the body, adding to that visual bulk and keeping it from fitting easily under low-lying furniture. There are also some visible gaps in the construction that keep it from feeling fully polished.

User maintenance is very time-consuming, largely because of how many parts require regular attention across the robot and the dock. Most of them are easy to access and clean, but a few things are less convenient: the side brushes require a screwdriver to remove, and the mop cover is secured by three small screws that can fall into gaps in the robot housing and become difficult to retrieve. The brush roller accumulates hair quickly enough that it can jam if you don't clear it regularly.

The Roborock Curv 2 Flow is expensive to maintain because it has several parts that need to be replaced regularly.
Parts you'll eventually need to replace include:

The dock has great self-maintenance capabilities, using the same dock and bags as the original Roborock Qrevo Curv. It handles most day-to-day tasks automatically, so you won't have to do much hands-on maintenance work between sessions. It empties the dustbin into a large bagged dirt compartment, washes the roller mop with hot water (167 °F), dries it with hot air (131 °F), and automatically refills the robot's onboard water tank before the next run. There's also a self-cleaning cycle for the cleaning tray, cutting down on one more manual maintenance task.

Hard floor pickup is good in Balanced mode with Standard pathing, clearing the majority of debris from open areas without scattering much around. That said, it can't match the performance of the original Roborock Qrevo Curv. You'll find small amounts left behind along edges, baseboards, and corners, so you might need to clean them manually. One quirk is the dustbin design, which can allow finer debris to spill back out during cleaning. If you notice it becoming a problem, try using Maximum suction to resolve the issue.

High-pile carpet pickup is okay, but if your home has a lot of high-pile rugs or carpeting, you'll likely need to supplement with manual vacuuming. It handles most debris in open areas when using Balanced mode with Standard pathing and Carpet Boost enabled, but leaves a noticeable amount behind along baseboards and in corners.

The Roborock Curv 2 Flow does an adequate job of cleaning low-pile carpets, but it doesn't do a thorough enough job to completely replace manual cleaning when using Balanced mode with Standard pathing and Carpet Boost enabled. You'll likely notice dirt left behind in corners and along baseboards, and it also scatters some debris around as it cleans.

Pet hair pickup on carpets is poor, with a large amount of hair left behind after each cleaning pass when using Balanced mode with Standard pathing and Carpet Boost enabled. If you have shedding pets, this robot vacuum isn't reliable enough to keep up with hair buildup. The main issue is that the brush roller struggles to effectively agitate the carpet fibers, leaving much of the hair embedded in the material.

The Roborock Curv 2 Flow is impressively quiet, so you can let it run while you work or sleep without worrying about it disturbing you. It gets louder at higher suction settings, as expected, but stays reasonable even at Max. The dock is noticeably louder during auto-emptying, so expect a brief burst of noise at the end of each cleaning session.

This robot vacuum does a decent job adapting to your home, navigating well around most furniture, and cleaning under chairs and around lightweight items without getting stuck. That said, rugs with tassels or fringe can be a problem because the vacuum tends to get tangled and requires you to step in. Reflective surfaces like mirrors can also occasionally cause minor navigation confusion, despite the robot detecting them. It can also bump into mirrors even after detecting them. One more thing to note is that its taller body limits its ability to clean under low-profile furniture.
for videos & test results
While this robot vacuum does an okay job avoiding obstacles, improving performance compared to the original Roborock Qrevo Curv, it varies significantly depending on the surface. On bare floors, it navigates around objects well and rarely needs you to step in. On carpet, however, it struggles much more, frequently bumping into obstacles and requiring intervention more often. It also doesn't consistently avoid pet waste, so if you have pets, there's a real risk of it making a mess if it encounters any accidents.

The Roborock Curv 2 Flow does a decent job on stains, removing a large portion of residue on a second pass. One thing to note is that the stain detection feature doesn't work as reliably as on other Roborock models, so the robot may not automatically focus extra attention on dirty areas. Additionally, the mop roller still looks quite dirty after the dock washes it.

Like most robot vacuums, the Roborock Curv 2 Flow shouldn't be used to pick up large liquid spills in order to avoid potential damage.
While you need the app to control most advanced functionality, there are some physical controls for basic commands. The Power/Clean button turns the robot on and off and starts cleaning, while the Dock button sends it back to the base and triggers emptying when it's docked. Holding the Dock button also starts a spot clean or mop wash, depending on whether the robot is on the dock or not.

The app is outstanding, covering all the features you'd expect from a high-end robot vacuum. A few additions are worth noting: you can map out your carpets by shape and pile type so the robot cleans them more precisely, and a scheduled Cruise mode lets it patrol your home on a camera loop, which is handy if you have pets or travel often. The app also supports Matter, making it easy to integrate into a broader smart home setup with products from other brands. Additionally, the remote control lets you spot clean and manually cover or uncover the roller mop as needed.
