Based on a review by Vacuum Wars (accessed 2026-02-20).
Based on this review alone: skip it — poor mopping performance on dried stains (25 points out of 112 average), unless good at sweeping debris of all sizes from hard floors and carpets is your only priority.
The reviewer concluded that the Roborock Qrevo Curv 2 Flow did not live up to expectations, especially at its price point, primarily due to significantly poor mopping performance, below-average obstacle avoidance, and struggles with flattened pet hair. Despite some improvements like a larger dustbin and excellent navigation, the reviewer suggests earlier Curv models, particularly the CurvX, remain stronger choices.
This video review from Vacuum Wars covers the Roborock Qrevo Curv 2 Flow, Roborock's first roller mopping robot vacuum. The reviewer conducts weeks of independent testing, detailing its performance in sweeping, carpet deep cleaning, hair tangle prevention, mopping, navigation, and hardware features, often comparing it to the previous CurvX model.
The Roborock Qrevo Curv 2 Flow is a disappointment, especially given its upper-middle price point, as its new roller mop system underperforms significantly. While it excels at vacuuming, achieving an 87% carpet deep clean score and a perfect 0% hair tangle score thanks to its DuoDivide brush, its mopping performance on dried stains scored an "unbelievably low" 25 points out of an average 112. Additionally, obstacle avoidance was subpar, recognizing only 16 out of 24 objects, which is worse than prior models. If you prioritize excellent vacuuming and hair handling, it's decent, but if effective mopping or robust obstacle avoidance is crucial, consider older Curv models like the CurvX, which offer better overall performance.

The Qrevo Curv 2 Flow scored an above-average 87% in the carpet deep clean test, where a measured amount of sand is embedded into medium-pile carpet and weighed after removal. This is a strong performance, though it trailed the CurvX's 92%.
comparisonpositive
The robot features a 20% increase in onboard dustbin size compared to the previous CurvX model, which had a very small dustbin. This is a welcomed hardware improvement.

The DuoDivide rubber main brush achieved a perfect score of 0% hair tangled in the 7-inch hair tangle test, which is much better than average. This design effectively channels long hair to prevent wrapping.

The mop lifts 15 mm over carpets and includes a carpet shield, allowing the robot to clean both hard floors and carpets in a single run without wetting carpets.

The roller mop extends to the side for effective cleaning along the edges of walls and furniture. It also exerts 15 Newtons of downward pressure for better scrubbing.

The Curv 2 Flow uses top-mounted spinning LiDAR, and its navigation scores were excellent, even pulling slightly ahead of the CurvX's already impressive navigation.
measurement_testnegative
The airflow in a bench test was not impressive, scoring a just-below-average 16 CFM.
measurement_testnegative
Despite claims of improved Reactive AI, the robot only avoided 16 out of 24 combined objects in basic and torture tests, trailing the CurvX's 20-object score. This performance was below expectations.
measurement_testnegative
In the traditional dried-on stain test, the Curv 2 Flow scored an unbelievably low 25 points out of an average score of 112, indicating very poor mopping effectiveness.
measurement_testnegative
The combined score for the mop was a very low 13.7, placing it as the 11th lowest score among all robots ever tested by the reviewer. This confirms significant issues with the mopping system.
measurement_testmixed
The robot left behind only 0.2 g of water in the water penalty test, which is below the average of about 1 g and far below the CurvX. This suggests it might be under-applying water, contributing to poor stain removal.
measurement_testnegative
The bench test for suction yielded a score that was about half of the average, similar to the CurvX. While suction numbers don't always reflect real-world performance, it's a noted area of weakness.
measurement_testnegative
Both the Curv 2 Flow and the CurvX performed poorly in the flattened pet hair test, where 2.5-inch hair is pressed into carpets. They received the exact same below-average scores.
reviewer_claimnegative
The low battery efficiency meant the Curv 2 Flow could only cover less than 1,300 estimated square feet per charge, which is below average and significantly less than the CurvX.
visual_inspectionnegative
The robot has a surprisingly tall profile of 4.7 inches (119 mm), which is considered high for a robot vacuum at any price point, even with a top-mounted LiDAR.
The Roborock Qrevo Curv 2 Flow achieved an above-average score of 87% in the carpet deep clean test. It is also noted for doing a good job sweeping debris of all sizes from carpets, making it a good vacuum for carpeted areas.
The Roborock Qrevo Curv 2 Flow performed exceptionally poorly in dried-on stain tests, scoring just 25 points out of an average of 112. Even with the highest water flow setting, it only reached 38 points, and its overall mop score of 13.7 ranks among the lowest ever tested by the reviewer.
The Roborock Qrevo Curv 2 Flow features a DuoDivide rubber main brush designed to channel long hair and prevent tangles. It achieved a perfect score of 0% hair tangled in the 7-inch hair tangle test, demonstrating excellent performance in this regard.
The Roborock Qrevo Curv 2 Flow's mop lifts 15 mm when it detects carpets and also features a carpet shield. This design allows the robot to seamlessly transition between and clean both hard floors and carpets within a single cleaning run without wetting the carpets.
The Roborock Qrevo Curv 2 Flow exhibited poor battery efficiency. This resulted in an estimated cleaning coverage of less than 1,300 square feet per charge, which is considered below the average for robot vacuums and significantly less than its predecessor, the CurvX.
Despite claims of an upgraded Reactive AI, the Roborock Qrevo Curv 2 Flow only managed to avoid 16 out of 24 combined objects in the reviewer's basic and torture tests. This performance trails significantly behind the CurvX's score of 20 objects, indicating a sub-par obstacle avoidance system for its class.
The Roborock Qrevo Curv 2 Flow measures 4.7 inches (119 mm) in height. This profile is considered surprisingly tall for a robot vacuum at its price point, even with a top-mounted LiDAR, which could potentially limit its ability to clean under lower furniture.
100/100 source quality
The Vacuum Wars channel reviewed the new Roborock Qrevo Curv 2 Flow, subjecting it to weeks of independent testing. While the robot vacuum demonstrated strong performance in sweeping debris from various surfaces, achieving an 87% score in carpet deep cleaning and a perfect 0% for hair tangles, its mopping capability for dried-on stains was found to be exceptionally poor, scoring only 25 out of an average 112 points. Additionally, its obstacle avoidance was below expectations, avoiding only 16 of 24 objects compared to the CurvX's 20. The reviewer praised its navigation and app features but ultimately recommended previous Curv models as better alternatives for now.
