Roborock Qrevo CurvX

The Slimmest Roborock Yet Can Clean Where Others Can’t Reach

At just 3.14 inches tall with its LiDAR retracted, the Roborock Qrevo CurvX slips under furniture that would stop most robot vacuums cold. That’s the headline feature here, but there’s plenty more going on with this 2025 refresh of the popular Qrevo Curv.

The CurvX landed in North America on May 26, 2025, with an MSRP of $1,500. Street prices have already dropped to $849-$1,100 depending on promotions. It’s available in white only through Amazon, Best Buy, Target, Walmart, Home Depot, and Roborock’s own site.

What changed from the Curv? Suction jumped from 18,500 to 22,000 Pa. The dock now washes mops at 80 degrees Celsius instead of 75. And that retractable LiDAR system lets the robot duck under low-hanging sofas and bed frames.

Hardware That Actually Delivers

Cleaning Power

The 22,000 Pa suction claim checks out, though actual measured performance tells a more nuanced story. Vacuum Wars tested airflow at 13 CFM and absolute suction at 0.54 kPa, which falls slightly below the category average of 0.96 kPa. In practice, though, this still means 92% debris removal on medium-pile carpet during standardized testing.

The DuoDivide brush system deserves special mention. This dual-section anti-tangle roller is an industry first, and it works remarkably well. SGS certified the design for zero hair tangling and 100% hair removal, claims that real-world users have largely confirmed. Pet owners with long-haired dogs report going months without cleaning the brush.

One genuine design flaw: the 258 ml dustbin loses about 30-40% of its capacity to unusable space around the air filter. Multiple owners on Reddit have confirmed debris overflows before the bin is truly full.

Navigation and Obstacle Detection

The RetractSense LiDAR does something clever. When approaching low furniture, it retracts to give the robot that ultra-slim 7.98 cm profile. In raised position, you get standard LiDAR navigation. The rear-facing field of view in retracted mode covers 100 degrees, which is narrower but sufficient.

For obstacle avoidance, the CurvX combines structured light with an RGB camera to recognize 108 different objects. Testing shows it handles obstacles down to 5 cm wide and 3 cm tall. The system works in both bright and dark rooms, with Vacuum Wars scoring it 20 out of 24 on their obstacle avoidance tests, well above the 17-point average.

Battery and Coverage

A 5,200 mAh battery provides 220 minutes of runtime in Quiet mode, dropping to around 100 minutes at maximum power. Tested coverage hits about 1,445 square feet per charge at typical settings, exceeding the market average of 1,100 square feet.

Energy efficiency runs at 1.7 minutes per battery percentage point, beating the average of 1.3. Charging happens 30% faster than the previous Curv model, and the app supports off-peak charging if you want to minimize electricity costs.

Physical Capabilities

The AdaptiLift chassis handles thresholds up to 40 mm by lifting individual sections of the robot as needed. Unlike simpler systems that raise the whole body, this can adjust front, rear, left, or right sections independently based on terrain.

That 3.14-inch profile in retracted mode means the CurvX can clean under furniture that would block robots standing at the more typical 4+ inches.

Mopping That Mostly Works

Dual rotating microfiber pads spin at 200 RPM and press down with up to 12N of pressure when you enable the Deep Cleaning mode for heavy dirt. The pads lift 17 mm to avoid carpet, and the FlexiArm design extends to reach edges and corners.

The dock handles mop washing at 80 degrees Celsius, which Roborock claims eliminates 99.99% of bacteria (TUV Rheinland certified). Warm air at 45 degrees dries the pads over 2-4 hours.

Here’s where opinions diverge. Some users report excellent mopping results. Others see brown stains on tile and complain about the robot spreading dirt rather than cleaning it. Hard water seems to make this worse. If you live somewhere with mineral-heavy water, plan accordingly.

The dock’s 4-liter clean water tank handles about 3,550 square feet of coverage before needing a refill. Dirty water capacity sits at 3.25 liters.

App and Smart Features

The Roborock app rates 4.8 stars on iOS (586,000+ reviews) and 4.6 stars on Android. That’s not accidental. The interface is genuinely well-designed.

Mapping happens automatically on the first run, with support for up to four floor plans and automatic floor detection. Full 3D mapping is available for visualization, and you can edit room boundaries, name rooms, and place virtual furniture.

Cleaning modes include Auto, Quiet, Balanced, Turbo, Max, and Max+ for vacuuming, with separate water flow controls for mopping. The SmartPlan 2.0 AI customizes cleaning based on room type, floor material, and your usage patterns over time.

Voice control works through Alexa, Google Home, and Siri Shortcuts. There’s also a built-in “Hello Rocky” wake word that works offline for basic commands. Matter protocol support is promised but wasn’t live as of December 2025.

Pet owners get special features: automatic recognition that stops brushes when approaching pets, location tracking, photo captures during cleaning, and an active pet search function.

The Dock Experience

The Multifunctional Dock 3.0 Thermo+ handles self-emptying, mop washing, and drying in an 18-inch cube. It’s a substantial piece of equipment that needs dedicated floor space.

Dust collection uses sealed 2.7-liter bags that last roughly seven weeks each. A six-pack runs about $32, which works out to around $5-6 per bag. You can configure emptying frequency, with some users stretching to 65 days between bag changes.

The dock’s self-cleaning feature sprays 80-degree water to clean its own nozzles and brush areas. The detachable base makes periodic deep cleaning straightforward.

What’s in the Box

You get the robot, the dock, two mop pads, a main brush cover, one side brush, one dust bag, a HEPA filter, a cleaning tool, a USB charging cable, and documentation.

You’ll want to buy extra dust bags right away since you only get one. Additional mop pads are also worth grabbing. A four-pack of CurvX-specific mop cloths runs $29.99.

Annual maintenance costs typically fall between $150-$220, covering bags, filters, mop pads, and occasional brush replacements. Third-party parts on AliExpress can cut that by 40-60%, though quality varies. Stick with official parts for filters and dust bags.

Real-World Performance

By Floor Type

Hardwood and tile perform excellently with no scratching issues. Low-pile carpet sees strong results, and medium-pile benefits from the AdaptiLift chassis adjusting for optimal contact. High-pile carpet works but with caveats: pile exceeding 3 inches may see missed spots despite the chassis lifting 10 mm to prevent clogging.

Transitions between floor types handle smoothly, including the 40 mm thresholds the AdaptiLift is designed for.

By Debris Type

Fine dust, sand, cereal, rice, pet litter, and all types of pet hair: the CurvX handles them well. The anti-tangle brush system genuinely delivers for pet owners. Users with short-haired dogs report virtually no brush maintenance, and the robot manages hair up to 40 cm long without wrapping.

Edge and Corner Performance

The extending side brush and mop reach right to edges, with certification for 0 mm clearance. Corners perform slightly worse for mopping, with occasional streaks reported, though vacuuming coverage is excellent.

Navigation Quirks and Getting Stuck

The SmartPlan 2.0 AI produces methodical grid-based cleaning with room recognition. Coverage efficiency exceeds average, with most users reporting 1-3% of floor space missed, typically in edges and tight corners.

Common trouble spots: low-hanging shelves where the LiDAR can’t detect overhead obstacles, corners with long curtains, and high-pile rug fringe. The robot reverses and finds alternate routes when stuck, sending app notifications when it truly can’t escape.

In cluttered homes, expect 1-2 stuck incidents monthly. Tidy homes often see zero. The slim profile dramatically reduces under-furniture entrapments compared to standard robots.

Mirrors and reflective surfaces can confuse the navigation, occasionally registering as open space. Virtual barriers solve this if your home has large mirrors near floor level.

Pet Compatibility

This is where the CurvX shines. The anti-tangle brush system genuinely eliminates the hair-wrapped-around-everything problem that plagues other robot vacuums. The camera recognizes pet waste and stops to notify you, though liquid messes may spread before detection.

Most pets tolerate or ignore the robot. The 78 dB self-emptying process is the loudest part and may startle sensitive animals.

Known Issues Worth Considering

Beyond the dustbin capacity problem, some units have leaky dirty water tanks. Forum activity suggests 5-10% of units are affected. Some owners report the self-emptying mechanism jamming when hair accumulates around the flap.

App connectivity can drop in congested Wi-Fi networks, though this usually resolves with an app restart. Cliff sensors occasionally over-react to black rugs despite calibration, but virtual barriers work around this easily.

How It Compares

Versus the Qrevo Curv: The CurvX gains 3,500 Pa of suction, 0.5 cm less height, and 5 degrees hotter mop washing. It loses battery capacity (5,200 mAh versus 6,400 mAh). The retractable LiDAR is the real differentiator. Worth upgrading? Only if you have extreme low-furniture needs or your Curv is having problems.

Versus competitors at $1,300-$1,600: Vacuum Wars ranked the CurvX first in this bracket for obstacle avoidance, app quality, and customer support. The Ecovacs DEEBOT X9 Pro Omni and Dreame X40 Ultra offer alternatives with their own strengths, but Roborock wins for pet owners specifically.

Who Should Buy This

The CurvX makes sense for pet owners (those anti-tangle brushes are genuinely transformative), homes with high thresholds (the AdaptiLift handles 40 mm), and anyone who wants set-and-forget operation.

Skip it if you primarily need mopping performance (results are inconsistent), have extremely tight spaces, or want to spend under $500.

Support and Warranty

Standard warranty runs one year from purchase with extensions available. Roborock’s customer support ranks highest among robot vacuum brands per Vacuum Wars, with 24/7 availability via phone (888-960-4321), email, and in-app chat.

The r/Roborock subreddit has 100,000+ members for community support, and official documentation is comprehensive.

The Bottom Line

The Roborock Qrevo CurvX represents iterative improvement over an already-strong product. The retractable LiDAR and slim profile genuinely expand where the robot can clean. Pet owners will love the anti-tangle system. The app remains industry-leading.

Just know that mopping results vary by home and water quality, the dustbin design wastes capacity, and some units have water tank issues. At current street prices around $850-$1,100, it’s competitive value for what you get.
