Roborock Qrevo S Pro vs Qrevo CurvX: Is the Upgrade Worth It?
Short answer: The Qrevo S Pro, for most homes. It does the same daily jobs with far fewer reliability complaints. Buy the CurvX only if your sofas and beds sit under 3.8 inches or long hair keeps jamming your brushes.
Roborock Qrevo S Pro
4.1★ · 6,855 ratings
- You want the full dock without paying flagship money
- Reliability matters more than the newest sensor tricks
- Your furniture clears about 4 inches
Roborock Qrevo CurvX
4.1★ · 4,889 ratings
- Your sofa or bed is too low for a 3.8-inch robot
- You have thick door thresholds or rug edges up to about 1.6 inches
- Long human hair or pet fur constantly wraps your current brush
Both robots live in the same kind of home: one with hard floors to mop, a few rugs, and an owner who’d rather never touch a dust bin. Both docks empty the robot into a bag, wash the spinning mops in hot water and dry them with 113°F air. So what’s the CurvX’s extra money buying? Mostly height, sensors and climbing. Whether that’s worth it comes down to your furniture.
Side by side
| Qrevo S Pro | Qrevo CurvX | |
|---|---|---|
| Navigation | Fixed LiDAR | Retractable LiDAR |
| Obstacle sensing | Structured light | Structured light + RGB camera |
| Robot height | 3.8 in | 3.14 in |
| Mop wash | 167°F | 176°F |
| Claimed suction | 18,500 Pa | 22,000 Pa |
| Claimed runtime | 180 min | 150 min |
| Reliability mentions | Not a top topic | 75% negative |
The deciding difference: reliability
This is what tips it. The CurvX listing has 287 reliability mentions, and 215 of them are negative, many describing units that quit within a few months. Its getting-stuck topic is 71% complaints. The S Pro has 6,855 ratings and reliability isn’t among its main topics at all. Its mapping comes out 87% positive across 243 mentions.
That’s not a lab result. It’s a pattern in owner feedback, and the CurvX is the more complicated machine, with a lifting chassis and a retracting turret.
Where the CurvX earns it
It fits. At 3.14 inches with the LiDAR dropped, Vacuum Wars calls it tied for the lowest robot it has measured. The S Pro’s fixed tower puts it at 3.8 inches.
It sees more. TechGearLab found it avoided 88% of the obstacles in its course, cords and shoes included. Basic Tutorials found the S Pro handled shoes and toys but missed flat cables.
It cleans carpet hard. Vacuum Wars measured 92% of embedded sand removed from medium carpet, tied for third of more than 205 robots. It also recorded zero hair tangling, and the extending edge mop reaches baseboards that the S Pro’s fixed mops leave alone.
Where the S Pro is the smarter buy
It does the daily work for far less, and more owners think it’s worth what they paid: 67% of value mentions are positive against 56% for the CurvX. The longer claimed runtime helps bigger single-floor homes too.
Its limits are real but manageable. Mark cable areas as no-go zones, add detergent by hand, and don’t expect it to keep up alone with a heavy shedder. Only 177 of 339 pet-hair mentions are happy ones.
Our pick
The Qrevo S Pro. Measure under your couch first, though. If a ruler says 3.5 inches, the CurvX is the only one of the two that will clean there.

Most owners say floors, hard floors especially, come out cleaner than before, and the map it builds earns 87% positive mentions.

What owners say about the Roborock Qrevo CurvX
Topics mentioned most in Amazon reviews, split into positive and negative mentions. Snapshot taken October 28, 2026.
When it works, owners praise its mopping, its pet-hair pickup and an accurate map. The problem is staying power: three in four reliability mentions are negative, often units quitting within months, and 71% of comments on getting stuck are complaints. Value splits nearly evenly.
FAQ
Does the Qrevo S Pro have a camera?
No. It avoids obstacles with structured light, and Basic Tutorials found it sometimes ran over thin cables. The CurvX adds an RGB camera to structured light and lists 108 object types it recognizes.
Do either of these add detergent automatically?
The Qrevo S Pro doesn't. Its dock has no detergent tank, so you add cleaner to the fresh-water tank yourself. Check the CurvX listing for your bundle before assuming it does.
Can the CurvX climb higher thresholds than the S Pro?
Roborock says its AdaptiLift chassis raises up to 4 cm, about 1.6 inches. Basic Tutorials found the S Pro managed thresholds up to 2 cm without trouble but struggled with taller steps.
Which is better for pet hair?
Neither is a sure thing. Only 52% of S Pro pet-hair mentions are positive. Vacuum Wars saw zero tangling on the CurvX, yet TechGearLab measured 52% pet-hair pickup and had to cut fur from its brushroll.
