Roborock Qrevo Curv: 18,500 Pa, new brushes, 4 cm threshold clearance! The best Roborock 2024!

Meet one of the most anticipated robot vacuums of late 2024—the Roborock Qrevo Curv. The new product went on sale in December. This robot vacuum boasts record-breaking suction power, reaching $185. It features a unique turbo brush that removes tangled hair and pet hair. It can lift its body to clear 4 cm thresholds. It extends a side brush to completely sweep away debris in corners. It also extends a cleaning cloth for scrubbing floors right up to baseboards. And like all other flagships, it can carefully navigate around objects even in complete darkness, self-empty its dust bin, and wash its cleaning cloths with hot water at the station, then dry them with warm air. It also features a proprietary voice assistant and remote home monitoring. Overall, this is a top-of-the-line solution for a reasonable price, which starts at $1,000 for pre-orders and shouldn't go higher than $1,350. So, below, I'll thoroughly test the Roborock Qrevo Curv, show you how it works, and then highlight the pros and cons based on the test results. So, let's get started!

Equipment

The new product comes standard with the robot vacuum cleaner itself, a station, a power adapter, two holders with cleaning cloths, a spare bag for the station, and an operating manual.

Appearance

It's much more interesting to examine the design. Let's start with the robot vacuum cleaner itself. It's round and comes in white. The body is 103 mm high.

The main feature is a wall sensor. A central system of sensors and cameras with LED backlighting detects and accurately navigates around objects on the floor.

The technology is called Reactive AI Obstacle Recognition, like its siblings Roborock S8 MaxV Ultra, Qrevo MaxV and Master.

The robot's camera allows you to remotely monitor your home using your smartphone.

The lidar is equipped with a spring-loaded cover. Next to it, we see two control buttons.

The dust container is located under the magnetically secured top cover. The container holds 325 ml.

The filtration system, as always, is HEPA-based. The robot has a water tank inside, but it's hidden within the body. It holds 80 ml. Water is automatically pumped into the tank at the station.

There are five fall protection sensors. There's also a carpet detection sensor. The side brush has been updated.

Not only does it reach into corners to completely sweep away debris, but it also features two beams instead of three. This helps prevent hair and fur from getting tangled up.

The central wiper blade is floating. The wiper blade itself has also been radically updated and given a new name: DuoDivide.

Now there are two bristled half-brushes with a gap in the center between them. Each half of the brush can be disassembled. The gap itself collects the wound hair and fur. I'll test the effectiveness of this idea and, most importantly, whether the gap causes any loss of power. I'll also add that the turbo brush rises during floor cleaning mode and when the robot returns to the docking station.

The cleaning pads are round, like those of other robots in the Qrevo line. Behind the right holder, you can see a mechanism that extends the pad to the edge of the body. This eliminates the blind spot between the edge of the pad and the baseboard, allowing the robot to better clean along walls and furniture.

I'd like to add that the cleaning pads automatically lift when entering carpets, when the robot returns to the cleaning station, and when the Roborock Qrevo Curv is directed to a designated room or cleaning area. Furthermore, the pads are also said to lift while drying at the cleaning station. The pad lift height has been increased to 10 mm.

The most important upgrade to the Roborock Qrevo Curv is its body lift. The entire body automatically lifts when the robot detects tall obstacles or medium-pile carpets. This means the robot vacuum can clear thresholds up to 4 cm high, a market record that will be further validated in testing. This technology is called AdaptLift.

As for the station, work has been done on it as well. We can see that the design has been changed. The rounded corners, reminiscent of Darth Vader's helmet, look futuristic. I liked the new shape of the station. It's also a little lower.

But there are some nuances. The robot's entry ramp is no longer removable. Only the napkin washing tray is removable. It's the same as the Qrevo Master's, consisting of two parts: the textured module itself, where the napkins are washed, and a tray with scrapers and a coarse filter. This means the station's tray automatically self-cleans when washing napkins.

The napkins are washed with hot water heated to 75 degrees and dried with warm air at a temperature of 45 degrees.

Under the top cover of the station there are water tanks and a garbage bag.

The tanks each hold 4 liters. A disinfection module is installed inside the clean water tank. The waste bag is standard. Unfortunately, there is no automatic detergent dispenser.

And finally, the last important point is connecting to the sewer and water supply. This particular station cannot be connected to utility lines. The official Roborock website shows a separate station for connecting to water and sewer lines, but I was unable to find this version of the robot for sale on the market.

We see a number of major updates compared to previously released ones. Qrevo MaxV And MasterThe pros and cons of the design will be outlined when summing up the results.

Technical specifications

The main characteristics of the Roborock Qrevo Curv, as stated by the manufacturer, are displayed on the screen:

• Li-Ion battery 6400 mAh.
• Suction power up to 18,500 Pa.
• Dust collector capacity is 325 ml.
• The water tank capacity is 80 ml.
• Obstacle clearance up to 40 mm.
• Robot dimensions: 353*103 mm.

Station:

• Clean water tank: 4 l.
• Dirty water tank: 3.5 l.
• Bag in the station: 2.7 l.
• Station dimensions: 450*450*450 mm.

There have been significant improvements in suction power and throughput, which will be verified in tests. The battery capacity has also been increased. All other parameters remain unchanged.

Functional capabilities

Speaking of features, the robot vacuum cleaner is controlled via the proprietary Roborock app. Connection is simple and convenient, the interface is in Russian, and the Russian version of the robot itself even has voice notifications in Russian. The global version doesn't have a Russian voice package, which is important to keep in mind.

Main features of Roborock Qrevo Curv:

• Self-cleaning at the station.
• Washing napkins at the station with hot water.
• Drying napkins with warm air.
• Side brush extension in corners.
• Moving the holder with a napkin to the baseboard.
• Refilling the robot's water tank via the station.
• Recognizing objects on the floor.
• Remote home monitoring via camera.
• Saving multiple cleaning maps in memory.
• Automatic zoning of premises into rooms.
• Selecting areas and rooms for cleaning.
• Virtual walls and no-go zones (and for wet cleaning mode).
• Suction power adjustment.
• Adjusting the degree of wetting of the napkin.
• User mode.
• Cleaning log.
• Setting up cleaning according to a schedule.
• Automatic power increase on carpet.
• Carpet cleaning in wet cleaning mode.
• Lifting napkins when driving onto carpets.
• Raising the turbo brushes in wet cleaning mode.
• Raising the body when overcoming obstacles.
• Hello Rocky support.
• Voice notifications in Russian.
• Yandex.Alice support.

The robot's control via the proprietary "Hello Rocky" voice assistant deserves special attention. You simply give the robot a command by voice, and it carries it out. No third-party devices are required. Very cool! However, in the global version, phrases are perceived in English, which is not very convenient.

And overall, we've implemented a wide range of features to allow you to flexibly customize cleaning parameters to your specific needs. That's a plus!

Testing

A detailed video review with all tests has already been prepared and published on the channel:

Navigation

And finally, let's move on to the tests! First, we'll test the Roborock Qrevo Curv's navigation in a room with obstacles. The robot vacuum first navigates the room's perimeter, then cleans the entire accessible area in a serpentine pattern. The lidar created a false room behind a mirror, a problem common with all lidar robots. The dryer's legs presented no problems. It also swept around a box and chair legs separately, then returned to the station. The test was successful.

Speaking of navigating within the home, the Roborock Qrevo Curv cleans room by room, first along the perimeter, then in a serpentine pattern. After a selected time interval or after each room, the robot vacuum returns to the station and rinses its cleaning pads, then returns to clean where it left off. There are no uncleaned areas, the cleaning speed is high, and this model has excellent navigation!

Passing under low furniture

The minimum clearance height of the Roborock Qrevo Curv was also tested. Since it's 103 mm tall, testing it at the standard 10 cm clearance was pointless. However, it was able to pass at 105 mm clearance, which is good.

Object recognition

Speaking of the floor object recognition system, it performs well in good lighting. The robot vacuum accurately navigated all six objects, correctly displaying four of the six with corresponding icons on the map. It slightly brushed against a scale, a sneaker, a sock, and a cord, but left the most dangerous objects untouched. A good result!

The robot vacuum performed worse when recognizing objects in complete darkness. A toy and a sneaker were left untouched. It bumped a scale and ran over a simulated pet surprise. It chewed a cord and a sock. It correctly recognized two of six objects it hadn't actually touched. Moreover, these tests were conducted using the latest firmware version at the time of writing.

I've made the object recognition test more challenging to make it more accurate. The new test is a minefield. I don't think I need to explain it. In good lighting, the robot recognized and avoided three of the six traps, but decided not to approach the others, even though it had the physical ability to do so. In complete darkness, the robot drove past all six traps without recognizing a single one.

We move on – we tested wires of different colors and sizes in the same way. In good lighting, it avoided three of the four wires and correctly displayed them as icons on the map. It chewed up one wire. In complete darkness, the robot only identified one wire correctly, and it avoided two of the four. It chewed up the remaining wires and returned an error.

Another typical problem with robots is socks on the floor. Again, I used different colors. In good lighting, the robot vacuum cleaned neatly around all three socks, recognizing two of them as fabric and one black one as feces. In complete darkness, to my great surprise, it cleaned neatly around all three socks, but recognized all three as obstacles, not fabric.

Ultimately, I can say that the Roborock Qrevo Curv goes blind in complete darkness, and Roborock engineers need to address this. In good light, the object recognition system isn't perfect either, but overall, it's very effective, and I liked it.

Suction power

The power test that interested me most was the one I was most interested in. In Silent mode, the Roborock Qrevo Curv was only able to clean debris from a 2 mm gap. In Balance mode, the result remained at 2 mm. In Turbo mode, the robot partially cleaned a 4 mm gap. In Maximum mode, it cleaned a 4 mm gap even better. And in Max+ mode, the robot partially cleaned crevices 6 and even 8 mm deep. So, the robot's suction power is actually increased and higher than that of the S8 series, but 18,500 Pascals is still debatable. For example, the previously reviewed younger model Roborock Qrevo S was able to clean a 10mm gap at 7000 Pa.

So, aerodynamic losses remain an unresolved issue for Roborock engineers, but at least the results have improved significantly. Apparently, a change in the turbo brush design helped.

Dry cleaning

The collection performance of various types of debris on laminate floors is good, but there's a caveat. Even in corners, the robot vacuum cleaner cleans better than its peers in the lineup, which also have a retractable side brush. Again, the new side brush design likely contributed to this. The entire stand is completely clean!

The center and side brushes are clean. Bravo, Roborock engineers! Test successful!

I also tested the turbo brush's anti-hair and fur protection technology. I scattered some hair on the floor and ran the robot over the area. We see that some hair is collected in the dust bin. The turbo brush, however, is an interesting case. One half of the brush has caught some hair, but we see that most of it is actually being pushed toward the center. Apparently, the short duration of the test prevented the hair from fully dislodging from the turbo brush.

After this, I deliberately ran the robot vacuum cleaner under normal household conditions for a week without checking the brushes. I have long-haired housewives and a constantly shedding dog. In reality, only a minimal amount of hair remains on the shaft. And this hair doesn't affect cleaning performance at all; the blades are completely clean. I can say that Roborock's engineers did an excellent job here too!

Carpet cleaning

The Roborock Qrevo Curv cleans low-pile carpets well. In fact, it can also clean medium-pile carpets in just a few passes. This is all thanks to its well-designed brush and increased suction power!

Self-cleaning

Immediately after the "dirty tests," I'll check how well the robot vacuum cleaner self-cleans. We see that the dust bin is completely full. We return the robot to the station and start self-cleaning. The result is good. The dust bin is completely empty. The test was successful!

Wet cleaning and carpets

When it comes to wet cleaning on carpeted floors, the robot offers several different modes of interaction. It can carefully navigate around the carpet during wet cleaning, or it can enter and touch the carpet with its cleaning pad if you want to clean it with the robot. It can also clean carpets during wet cleaning, automatically lifting the cleaning pads and even the robot body when entering the carpet. The latter option is the most efficient.

Wiping off dirt

The cleaning performance is excellent. The wipes press firmly against the floor and absorb dirt. There's no narrow area along the baseboard, thanks to the wipes extending up to the baseboard. That's a plus!

Removing difficult stains

When it came to scrubbing tough stains, the robot even managed to remove dried-on coffee and sauce stains. And not on the first try. On the seventh, to be precise. And this is the best result I've seen in the Roborock line, and one of the best overall, compared to similar products. And I didn't even use any detergent, as none was included. The test was a success!

Washing quality of napkins

I'd like to immediately talk about the effectiveness of the station itself. Let's start with the cleaning quality of the wipes. Even after extensive testing, the wipes look significantly better after washing at the station. The water heating feature certainly improves the cleaning efficiency. In a domestic setting, after washing the floor, the wipes are thoroughly rinsed at the station. Dirt isn't washed away by the pressure of warm water. That's a plus.

I'd also like to point out that the wipes are also dried effectively. They dry completely on the station, thanks to the warm air drying!

Station maintenance

Even with the new scrapers in the tray, the station will still need to be washed by hand periodically. And here's the catch. Yes, you can remove the tray, which, even with the scrapers, will need to be washed by hand occasionally because hair and large debris clog the filter. But all of this is easy to clean. The drain, however, is non-removable and also gets dirty. It's less convenient to clean, and it's strange they didn't make it removable, like all previous models in the line.

Obstacle clearance

An interesting point is its ability to navigate thresholds. The Roborock Qrevo Curv can easily navigate 2 cm thresholds, which seems obvious. However, it struggles to navigate 3 cm thresholds. It also failed to navigate a 4 cm threshold, or more accurately, a 38 mm threshold, despite multiple attempts, no matter how much it raised its body or at what angles it tried. So, the new product certainly has excellent maneuverability, and it's currently the best robot vacuum on the market at this level, but I still can't confirm its 4 cm maneuverability.

Driving on black surfaces

Driving over black carpets is no problem. The robot glides over the black carpet as if nothing had happened.

Noise level

Well, as for the noise level, it is within 59-65 dB, depending on the selected operating mode.

The robot's noise level is actually very low, especially considering its increased suction power. The station's noise level during self-cleaning is approximately 69 dB. This is also a good result.

Personal opinion

The Roborock Qrevo Curv robot vacuum cleaner has been thoroughly reviewed and tested. our evaluation system he managed to gain 225 points and take second place in overall ranking of tested robotic vacuum cleaners in 2024. The robot fell just short of topping this rating, and that's due to a number of minor issues, which I'll discuss below. In the video description, I've included links to the evaluation algorithm and the overall rating of the tested robots. First, the pros. I liked the following:

1. The presence of a combined station for self-cleaning the dust collector, washing and drying napkins.
2. The station is highly efficient. It features high-quality self-cleaning, hot water washing, full-fledged warm-air drying, scrapers in the tray that make maintenance a little easier, and spacious tanks. In short, it's a comprehensive system that gets the job done.
3. The side and central brushes do not tangle hair and fur thanks to their updated design.
4. Improved maneuverability thanks to the raised body. The robot vacuum cleaner can overcome thresholds over 3 cm high, a feat not possible with similar products currently available on the global market.
5. The retractable side brush completely sweeps away debris from corners.
6. The napkin is pulled out close to the baseboard.
7. A backlit object recognition system that works effectively in good lighting conditions.
8. Lifting napkins when driving onto carpets.
9. Raising the turbo brush in wet cleaning mode.
10. Increased suction power.
11. High-quality dry and wet cleaning on various surfaces.
12. Capable of removing even stubborn stains faster than its analogues.
13. A large number of functions in the application.
14. Full Russification in the version for the Russian market.
15. Remote home monitoring by connecting to the robot's camera via a smartphone.
16. Control via the proprietary voice assistant Hello Rocky.
17. The robot vacuum cleaner is not afraid of black surfaces.
18. Low noise level of both the robot and the station.
19. High-quality assembly and high brand authority.
20. Availability of warranty and service.

As for the shortcomings, here are the ones that were identified:

1. The version of the station I received for review cannot be connected to the sewer or water supply. I couldn't find a model available with a different station designed for connection to utility lines. Overall, I personally don't find the solution with multiple station types logical. A single station with the option to purchase an additional module for connection to utility lines, as competitors do, would have been better.
2. There's no automatic detergent refill from a separate tank. This is also a rather odd decision, given the robot's price and the fact that it's scheduled to go on sale at the end of 2024.
3. Power losses are still observed, but they are now smaller.
4. The object recognition system becomes blind in the dark and therefore requires improvement.
5. A non-removable ramp for the robot to enter the station.
6. The robot vacuum cleaner couldn't overcome a 4 cm threshold, despite its stated clearance. Even a 3 cm threshold can be a challenge.

As a result, these criticisms alone caused the robot to lose over 10 points, thereby losing its spot as the best robot vacuum of 2024. However, it's truly autonomous, efficient, easy to use, and most importantly, reliable, as it's manufactured by a well-known brand and boasts excellent build quality. It's also a true off-roader in the robot vacuum market, making it far superior to its competitors, if that's important to you. Therefore, it's definitely recommended, definitely worth considering, and, what's more, I've even decided to keep it for at least a few months so I can finally gain some long-term experience with Roborock products.

In conclusion, I can say that unless these comments are critical to you, I see no compelling reason not to recommend this robot vacuum. If you have any questions, please ask them in the comments. Happy shopping. Bye!
