The Roborock Qrevo Curv S5X is a variant of the popular Qrevo Curv robot vacuum and mop combo. The Curv line performed extremely well in last year’s evaluations, and the S5X shares much of the same core hardware as the original model. However, Roborock scaled back certain features to reduce price, positioning this version as a lower-tier option within the Curv lineup. We bought one and put it through a series of independent evaluations over several weeks. In this Roborock Qrevo Curv S5X review, we’ll go over the pros and cons, highlight the results, and reveal whether the S5X earned a spot on the Vacuum Wars Top 20 Robot Vacuums list.
The Roborock Qrevo Curv S5X is a mid-range robot vacuum and mop combo in the Curv lineup that keeps many of the core strengths of the original model while trimming a few features to lower the price. In testing, it stood out for excellent vacuum performance, including strong pickup on hard floors and carpets and an impressive 93% score in deep-clean carpet tests. Its hardware includes a flexi-arm side brush for corners and Roborock’s Duo Divide anti-tangle main brush, which prevented hair wrapping even in long-hair tests. The dual spinning mop pads include an extending edge mop and can lift 10 mm over carpets, allowing simultaneous vacuuming and mopping. Mopping performance overall was moderate—below average in one stain test but above average in another—and it used less water than typical Curv models, reducing streaks. The third-generation dock is another highlight, offering hot-water mop washing, warm-air drying, auto dustbin emptying, dirty-water detection with re-mopping, and a self-cleaning tray. Navigation, battery efficiency, and the Roborock app are also strong. Downsides include weak obstacle avoidance due to the lack of a camera, a smaller-than-average onboard dustbin, and reports of debris being expelled if the bin overfills. See additional info

Overview of the Roborock Qrevo Curv S5X
The Qrevo Curv S5X is part of Roborock’s mid-range family of robot vacuum and mop combos. The series is known for its distinctive white dock with rounded styling, along with a strong balance of automation and cleaning performance.
Pricing fluctuates depending on sales and promotions, but the S5X typically sells for noticeably less than higher-tier Curv models. The lower cost is made possible by reducing certain features rather than building a completely different hardware platform.
Vacuuming Performance and Cleaning Power
One of the biggest strengths of the Roborock Qrevo Curv S5X is its vacuuming performance. The robot vacuum uses Roborock’s FlexiArm side brush, which extends to sweep debris out of corners and along edges, paired with the company’s DuoDivide main brush. The DuoDivide design channels hair toward a center gap to prevent tangles around the axle.
In our evaluations, the Qrevo Curv S5X did an exceptional job picking up debris of various sizes on hard floors and carpets, with no noticeable scattering. But the most impressive result came from our deep cleaning evaluation, which measures how well a robot removes deeply embedded sand from medium-pile carpet.
The S5X achieved a score of 93 percent. That result ranks among the top three out of over 175 robot vacuums we’ve evaluated.
Hair Pickup and Anti-Tangle Performance
Hair pickup was another strong category for the S5X. The robot removed 89 percent of the embedded hair in our 2.5-inch pet hair evaluation, where hair is pressed into medium-pile carpet to simulate real-world conditions. The average score across our database is 81 percent, which puts the S5X comfortably above average.
It also did very well with hair tangles. In our 7-inch hair tangle evaluation, the Qrevo Curv S5X had zero percent of the hair wrap around the brush. By comparison, 28 percent of the hair becomes tangled in the brush roll of the typical robot vacuum in this evaluation.
That makes the S5X a particularly strong option for homes with pets or long hair.
Mopping System and Stain Removal Performance
The Roborock Qrevo Curv S5X comes with a dual spinning mop pad system, with one pad designed to extend outward to reach edges along walls and furniture. The pads also automatically lift 10 millimeters whenever the robot detects carpet.
That means it can vacuum and mop in a single run without wetting carpets, which is great if you have mixed flooring.
In terms of stain removal, the results were somewhat mixed. In our legacy dried stain evaluation, the Curv S5X achieved a score of 87 points, compared to an average of 112.
However, the robot vacuum performed above average in our newer stain removal assessment, achieving 108 points compared to an average of 99.
One area where the S5X stood out was water usage. It used only about 0.55 grams of water on the medium water setting, while the average robot vacuum in our database uses roughly 1.05 grams.
Curv models have historically used higher water output to improve stain removal, but that can sometimes leave floors looking streaky. So while the S5X’s stain results were decent, it achieved them with more conservative water usage.
Households that want stronger stain removal can increase the water flow in the app. But as configured out of the box, the S5X delivers solid everyday mopping performance.
When we combine those mopping results, the Qrevo Curv S5X lands roughly in the middle of the pack for overall mopping performance. Its combined mop score was 21, compared to an average score of 23 across the robots we’ve evaluated.

Multifunction Dock and Automation Features
Another major strength of the Qrevo Curv S5X is its docking station. The robot vacuum uses the third generation of Roborock’s multifunction dock, which includes several automation features designed to reduce maintenance.
The dock automatically washes the mop pads with hot water and dries them with warm air to help minimize bacteria growth and odors. It also monitors how dirty the wash water becomes and can trigger automatic re-mopping of especially dirty areas.
In addition, the dock automatically empties the robot’s onboard dustbin into a disposable bag. The base station includes a self-cleaning function, and the detachable tray makes it easy to remove and clean the dock base for more hands-on maintenance.
Navigation and Mapping Performance
A top-mounted LiDAR sensor handles navigation, and the Curv S5X performed very well in this area. The robot vacuum covered 0.84 square meters per minute, compared with an average of 0.75 square meters across robots we’ve evaluated.
Battery efficiency was another highlight. The S5X delivered approximately 1.69 minutes of cleaning time per 1 percent of battery capacity used. The average robot vacuum in this category achieves around 1.31 minutes per percent, meaning the Curv S5X performs roughly 25 percent better than average.
When we combine these efficiency metrics, the S5X covers an estimated 1,528 square feet per charge. That’s significantly higher than the average of about 1,109 square feet.
Roborock App Features and Controls
Roborock’s mobile app remains one of the strongest in the robot vacuum industry. The app provides detailed control over suction levels, water flow, and cleaning behavior. For example, you can enable mopping along the direction of the floorboards to reduce the appearance of streaks. Other standard features include scheduled cleaning, room-specific customization, and no-go zones.
However, the Qrevo Curv S5X doesn’t include a camera. So it lacks some of the extra features that camera-based robot vacuums offer, such as pet detection and photo capture. That missing camera also contributes to one of the robot’s biggest weaknesses.

Cons of the Roborock Qrevo Curv S5X Robot Vacuum
These potential drawbacks we found during our Roborock Qrevo Curv S5X review may mean some households will find it lacking, even though it performed well in several core areas.
Obstacle Avoidance Performance
The most significant downside of the Roborock Qrevo Curv S5X is its obstacle avoidance system. The robot vacuum relies on Roborock’s Reactive Tech obstacle avoidance, which uses LiDAR combined with 3D structured light sensors to detect objects in its path.
This system is more advanced than basic bumper-only robots, but it’s generally less reliable than camera-based obstacle detection systems. That difference showed up in our evaluation results.
The Curv S5X successfully avoided only 7 out of 24 obstacles in the basic and torture evaluations. The average score for robots in this category is 16 out of 24.
While the S5X provides some obstacle awareness, households may need to tidy up small items before runs, such as cables and floor clutter.
Dustbin Size and Real-World User Feedback
Another potential drawback is the robot vacuum’s onboard dustbin size. The Curv S5X dustbin holds just 325 milliliters, which is roughly 25 percent less than the average robot’s dustbin capacity of 400 milliliters.
In our review process, we also examine real-world user feedback from sources such as Amazon and Reddit. While most owners report positive experiences with the S5X, one recurring complaint is that debris is spit back out after the robot runs for a while.
This behavior is often associated with an overflowing dustbin, which can happen with a smaller bin capacity. Increasing the frequency of automatic dustbin emptying or running the robot more frequently can help reduce the issue.
Roborock Qrevo Curv S5X Review: Did It Make the Top 20?
Overall, the Roborock Qrevo Curv S5X delivered strong evaluation results and retained many of the core strengths that made the original Curv series popular. Its vacuuming performance is excellent (especially on carpet), and its efficiency scores in navigation and battery usage were well above average.
The mopping system provides decent everyday cleaning, although it doesn’t stand out as one of the strongest performers in stain removal. The biggest tradeoff is the obstacle avoidance system, which performed well below the current industry average.
Even with those compromises, the Curv S5X still performed well enough overall to narrowly secure a spot on our Top 20 Robot Vacuums list at the time of this review.
For households seeking stronger obstacle avoidance, some higher-tier Curv models may be worth considering. Several of those models currently rank on the Vacuum Wars Top 20 list, which we continuously update to reflect the latest assessment results.
