Roborock Qrevo CurvX Robot Vacuum Review: Real World Results

Roborock Qrevo CurvX Robot Vacuum and Mop Review – Updated!

The Roborock Qrevo CurvX is Roborock’s latest flagship robot vacuum and mop, packed with high-end features and specs. We bought one and tested it over several weeks in a variety of real-world scenarios. We first reviewed this robot vacuum about a month ago, but after using it at home and doing additional testing, we ended up liking it much more than we did at first—enough that it made us revisit how we score robot vacuums at Vacuum Wars. Following a major update to our ranking algorithm, the Qrevo CurvX jumped to the number two spot on the Vacuum Wars Top 20 Robot Vacuums list, a significant improvement over its original placement.

Roborock Qrevo CurvX Basics and Key Features

The Qrevo CurvX is a robot vacuum mop combo and includes an auto-empty bin that washes and dries its mop pads. The CurvX is the successor to the Qrevo Curv, released last year. Both are known for the interesting shape of their multifunctional docks, which Roborock designed to be more aesthetically appealing.

Roborock Qrevo CurvX Review: Pros and Performance Highlights

Let’s start with what the CurvX gets right.

Hardware and Brush Design

The CurvX features Roborock’s DuoDivide main brush, which channels hair to the center of the brush as it vacuums to prevent tangling. And it uses that new brush in combination with its newer anti-tangle side brush, which automatically extends for better corner coverage. 

Everything regarding these worked well in our evaluations.

Hair Tangle Resistance and Debris Pickup Results

In our 7-inch hair tangle assessment, the CurvX had 0% of the hair tangled, whereas the current average of all the robot vacuums we have evaluated is 28%.

In general, the CurvX’s two brushes worked very well together to pick up debris from both hard floors and carpets, similar to most Roborocks we’ve evaluated.

The CurvX has especially impressive carpet deep cleaning capabilities, picking up 92% of the deeply embedded sand in a timed assessment on medium carpet. It tied for third place overall out of over 150 robot vacuums evaluated.

It’s an excellent product for basic vacuuming and sweeping.

RetractSense Navigation: LiDAR Mapping and Low-Furniture Access

The new RetractSense Navigation System is essentially a retractable top-mounted LiDAR. The idea is to provide all the benefits of a top-mounted LiDAR (our best sensor type for mapping and navigation) but make it retractable. Specifically, the LiDAR turret retracts whenever the robot senses low furniture to get under it.

And the CurvX is particularly slim when the LiDAR turret is retracted. It’s just 3.14 inches, which is about an inch shorter than average. It’s tied for the lowest height we’ve seen on a robot vacuum, whether it has internal LiDAR navigation or not.

Navigation Accuracy and Battery Efficiency Tests

Efficiency and coverage were slightly above average for its navigation performance. In our evaluations—where we ran the robot on a fixed floor plan at multiple power settings—the Roborock Qrevo CurvX demonstrated longer runtime and better energy efficiency than average. Its official battery life is 220 minutes, compared with 240 minutes for the previous Qrevo Curv and an overall average of about 148 minutes among models we’ve tested.

In terms of efficiency, it averaged 1.7 minutes of runtime per battery percent, slightly trailing the earlier model’s 1.8 but still above the market average of 1.3. These results indicate solid battery management and reliable endurance across cleaning modes.

Combining these results with its navigation scores, the Roborock Qrevo CurvX covered an estimated 1,445 square feet per charge—above the overall average of about 1,100 square feet, though still below the original Qrevo Curv’s 1,672 square feet per charge.

Obstacle Avoidance and Object Detection Performance

Another pro was its obstacle avoidance system. It uses Roborock’s Reactive AI obstacle recognition with structured light and an RGB camera to recognize and avoid objects that its LiDAR sensor and bump sensors can’t detect.

In our obstacle avoidance evaluation, the Roborock Qrevo CurvX scored 20 out of 24, outperforming both the previous Qrevo Curv and the overall average score of 17.

Obstacle avoidance is one area that we’re really glad to see Roborock improving upon.

Adaptive Lift Chassis and Threshold Crossing Performance

The Adaptive Lift Chassis allows the robot vacuum’s front wheels to lift automatically to cross high thresholds or similar obstacles up to 30 mm for a single tier or 40 mm for multi-tier. It also did well with this in our evaluations.

It can also adjust individual sections of the robot (front, rear, left, or right) based on the terrain, which is a particularly interesting feature. However, we didn’t assess that aspect of the Roborock Qrevo CurvX.

Multifunctional Dock: Mop Washing, Drying, and Auto Empty System

The robot vacuum’s multifunctional dock was a huge positive. Besides the distinctive curved shape, the dock is where the robot vacuum returns to charge. It will also automatically empty the contents of its internal dust bin into the disposable bag in the base. 

It uses 176° hot water to wash the mop pads, 113° warm air to dry them, and has intelligent dirt detection. Dirt detection is a sensor that can tell if the mop water is dirty and initiate more mop pad cleanings if needed.

The CurvX’s dock also has hot water dock self-cleaning, auto tank refilling, and a detachable dock base for manual deep cleaning if needed. So, it’s got all the right things in terms of mop pad management.

App Control and Smart Features Overview

You can adjust all the above-mentioned features in the app, and it’s one of the best apps out there in terms of app ratings and usability. 

It has the new Smart Plan 2.0, which learns your cleaning habits and adapts to different room types and floor surfaces. It also has virtual barriers, clean along floor direction (which we love), and lots of other control over the robot vacuum systems and scheduling.

Pet Recognition, Video Monitoring, and Smart Camera Features

The Roborock Qrevo CurvX comes with pet-specific features like real-time video calls. It can search for your pets when you’re not at home. It can also recognize them automatically and move aside to prevent scaring them.

Roborock Customer Service and Support Experience

We recently evaluated popular robot vacuum brands’ customer service, and Roborock scored the highest out of all of them. Customer service is essential because robot vacuums are complex devices with multiple moving parts and intelligent systems. When something goes wrong, responsive and knowledgeable support can save you time and frustration.

Roborock Qrevo CurvX Mopping Performance and Water Usage

On paper, the Qrevo CurvX has strong mopping features: dual spinning mop pads that apply downward pressure, automatic mop lifting on carpets, and an extending mop pad to better clean along edges. All of this worked well in our evaluations.

Qrevo CurvX Water Usage

A concern we had at first was how much water it used. Like the previous Qrevo Curv, the CurvX dispenses a relatively high amount of water when mopping. Even at the lowest water setting in the app, it put out 2.33 g per 4×4 test area in our measurements—more than double the average. We typically see that very high water output can cause streaking, especially on dark floors.

This finding led us to revisit how we score mopping performance in general. We realized that our system was penalizing robots too heavily for higher water output, which skewed results toward models that used very little water, even when that didn’t reflect better real-world performance. We also adjusted how much weight we give to our mop stain reduction test so that it no longer has an outsized influence on the overall score. We will cover the details about these changes in the near future.

Vacuum Wars Scoring Changes and Updated Ranking

However, after additional testing both in the studio and in a home with dark flooring that normally shows streaks easily, we did not see streaking from the Qrevo CurvX, even after multiple runs. In practice, its mopping performance was quite good, and the higher-than-average water usage did not translate into the problems we initially expected. As a result, we no longer see its water output as a severe drawback at the levels we measured.

Roborock Qrevo CurvX Review: Minor Con

Suction and Dust Bin Capacity

The Roborock Qrevo CurvX‘s drawbacks were relatively minor. In our airflow and suction measurements, it produced 13 cfm of airflow and 0.54 kPa of suction at maximum power—both slightly below the averages of 16.8 cfm and 0.96 kPa. While these numbers fall short of the category average, the CurvX still performed well enough in practical debris pickup and carpet cleaning to offset the difference.

Also, the internal dust bin was very small, well below average. So multiple runs per week will be necessary to stay ahead of pet hair if you have pets.

Roborock Qrevo CurvX Review: Final Results and Recommendation

After these algorithm changes, several models on the Vacuum Wars Top 20 Robot Vacuums list shifted by a position or two, while many stayed the same. The Roborock Qrevo CurvX robot vacuum and mop was the outlier: aside from the water concern, it was already a very strong product, so the updated scoring moved it significantly higher in the rankings – to the #2 spot, actually!

We believe these changes make the Vacuum Wars Top 20 Robot Vacuums list more accurate and useful in the long run, and we’re glad to give the CurvX the credit it deserves.
