Roborock Qrevo Curv: 18,500 Pa, new brushes, passage of 4 cm thresholds! The best Roborock of 2024!

Hey guys, welcome back to RobotObzor! Today, we’re checking out one of the most hyped robot vacuums of 2024 —the Roborock Qrevo Curv. This new model appeared on the market in Decemberi. It’s got some crazy suction power—18,500 Pascals, plus, it’s designed to avoid getting tangled with hair and can lift itself up to clear obstacles up to 1.6 inches (4 cm) high. The side brush extends to sweep up dirt from corners, and it even scrubs floors right up against baseboards. Like other high-end models, it avoids objects in the dark, empties its own trash, and even washes and dries its mop with hot water and air. It also has a built-in voice assistant and lets you check on your home remotely. The best part? It’s reasonably priced, starting at $1300 and expected to stay under $1600. Now, I’ll test out the robot’s features and functions, and let you know what I think about the robot. Don’t forget to leave a like and subscribe, and let’s get rolling!

Kit

Inside the box, apart from the station and robot, you get a power adapter, two mop holders, a spare trash bag for the station, and the manual. All pretty standard.

Appearance

Now, let’s talk about the design. The Qrevo Curv is a classic round and white robot standing at 4 inches (103 mm) tall.

One cool feature is the wall sensor. Right in the middle, there’s a set of sensors and cameras with LED lighting, helping it avoid obstacles even in low light.

This system, called Reactive AI Obstacle Recognition, is also in the Roborock S8 MaxV Ultra, Qrevo MaxV, and Master models. Plus, you can use its camera to check in on your home from your phone.

The lidar sensor has a spring-loaded cover, to save it from getting stuck under furniture, and next to it are two buttons.

Under the top cover (which is held in place by magnets), is an 11-ounce (325 ml) trash bin with a HEPA filter.

The water tank, holding 2.7 ounces (80 ml), is built inside the vacuum and automatically refills at the station.

The vacuum has five anti-drop sensors and a carpet detection sensor.

The side brush has been redesigned to extend into corners for better cleaning and has two arms instead of three to stop hair from wrapping around it.

The main brush is floating and was redesigned with DuoDivide. It’s made of two bristled half-brushes with a gap in the middle, where tangled hair and fur get directed. Each section can be removed. I’ll be testing if this design actually stops hair from clogging up and if the gap affects suction. Also, the turbo brush lifts up during mopping and when the vacuum returns to its station.

The mop pads are round, just like in other Qrevo models. The right-side mop holder has a mechanism that extends the pad to the edge of the body, helping it clean better along baseboards and furniture.

The mop pads also lift up when the vacuum moves onto carpets, heads back to the station, or switches cleaning zones. The lifting height has been increased to 0.4 inches (10 mm).

The biggest upgrade in the Qrevo Curv is that it can now lift its entire body. It raises itself when it detects large obstacles or medium carpets, helping it climb up to 1.6 inches (4 cm). This feature, called AdaptLift, is a first in the market, and I will for sure be testing how well it works.

As for the station, it’s had a bit of a redesign too. They gave it a rounder, more futuristic look, kind of like Darth Vader’s helmet. It’s also a bit shorter than before.

But, there are some downsides. The ramp leading into the station isn’t removable anymore — only the mop tray comes out. The tray itself has two parts: a textured surface where the pads are cleaned and a tub with scrapers and a coarse filter. The good news is the tray cleans itself when the mop pads are washed.

The mop pads are washed with hot water heated to 167°F (75°C) and dried with warm air at 113°F (45°C).

Under the station’s lid you’ll find the water tanks and dirt bag. The clean water tank holds 1.06 gallons (4 L), while the dirty water tank holds 0.92 gallons (3.5 L). The dust bag holds 0.71 gallons (2.7 L). Unfortunately, this model doesn’t have a built-in detergent dispenser.

Another thing to note—this station can’t be connected to the utilities. There is a separate version that supports this feature.

Compared to the Qrevo MaxV and Master models, this one has some solid upgrades. I’ll break down the pros and cons later on.

Technical Features

Here are the key specs for the Roborock Qrevo Curv:

• 6,400 mAh Li-Ion battery
• Suction power: up to 18,500 Pa
• Battery life: 240 minutes
• Cleaning area: up to 4,300 sq. ft. (400 m²)
• Trash tank capacity: 11 oz. (325 ml)
• Water tank capacity: 2.7 oz. (80 ml)
• Obstacle clearance: up to 1.6 inches (40 mm)
• Robot dimensions: 13.9 x 4 inches (352 x 103 mm)

Station:

• Clean water tank: 1.06 gallons (4 L)
• Dirty water tank: 0.92 gallons (3.5 L)
• Dirt bag capacity: 0.71 gallons (2.7 L)
• Station dimensions: 17.7 x 17.7 x 17.7 inches (450 x 450 x 450 mm)

The suction power and obstacle clearance have been seriously improved, so I’ll be testing both. The battery is also bigger, but the rest hasn’t changed.

Functionality

The Roborock Qrevo Curv is controlled through the Roborock app, which is super easy to connect to.

Here are the robot’s main features:

• Self-cleans at the station.
• Washes the wipes with hot water.
• Dries the wipes with warm air.
• Refills the water tank.
• Moves the wipe holder to the baseboard.
• Moves the side brush to clean corners.
• Recognizes objects on the floor.
• Remotely tracks the house with the camera.
• Saves multiple cleaning maps.
• Automatically divides the area into rooms and let’s you choose specific zones to clean.
• Virtual walls and no-go zones, even in mopping mode.
• Adjustable suction power.
• Adjustable wipe wetness level.
• SmartPlan for intelligent cleaning scheduling.
• Cleaning log and scheduled settings.
• Boosts suction power on carpets.
• Lifts wipes when cleaning carpets.
• Lifts the turbo brush for obstacle clearance.
• Voice alerts in several languages.
• Support Hello Rocky voice assistants.

You can control the robot with voice commands via the Hello Rocky assistant, which is pretty cool since you don’t need extra devices to do so. In general, the robot offers a lot of flexibility to adjust the cleaning parameters to suit your needs, which is a nice plus.

Testing

Quick video review:

Navigation

Now, let’s see how well the robot handles navigation. When cleaning a room, it first goes around the perimeter, then uses a snake-like pattern to clean the rest of the area. The lidar sensor did get a little confused by a mirror and created a fake room, which can happen with lidar robots, but it quickly recovered. It easily navigated around things like dryer legs and chair legs. Once it is finished, it returns to the station to clean its wipes and picks up where it left off. It was a smooth process overall, and the robot didn’t leave any missed spots. The navigation speed is fast and accurate.

As for the rest of the house, the robot tackled each room by outlining the perimeter first, then working in a zig-zag pattern. Every 15 minutes, it even returned to the station to rinse its wipes and picked up exactly where it left off! No spots left behind—navigation on this model is definitely impressive!

Passing Under Low Furniture

The robot’s height is 103 mm, so we checked how it fits under low furniture. It easily passed under 105 mm clearance, which is great for lower spaces.

Object detection

When it comes to recognizing objects, the Qrevo Curv did a good job in well-lit areas. It successfully avoided 4 out of 6 objects, recognizing most with icons on the map. It lightly brushed against a scale, a sneaker, a sock, and a wire, but didn’t knock anything important over. However, in complete darkness, it struggled. A toy and a sneaker went unnoticed, while it ran over the scale, some wires, and a sock. In this test, it recognized only 2 out of 6 objects correctly.

I tested it further with a “minefield” of objects to make it more challenging. In good light, it recognized and avoided 3 out of 6 traps. But in the dark, it ran over all of them.

For wires, in good light, the robot avoided 3 out of 4 different-sized wires and marked them correctly on the map. In the dark, it only correctly recognized one, while the rest were either missed or ran over.

For socks, in good light, it avoided all 3 socks and even recognized 2 of them as fabric. In the dark, it did well too, avoiding the socks, but it incorrectly recognized them as obstacles instead of fabric.

So, in dark conditions, the robot struggles a lot with Object detection, and Roborock engineers will need to improve that. In good light, though, the system works quite well, and I was impressed by its overall performance.

Suction Power

Now, let’s talk about suction power, which was the part I was most excited to test. In Silent mode, the Roborock Qrevo Curv could clean debris from a 2 mm (0.08 inches) crevice. In Equilibrium mode, it still could only clean up to 2 mm (0.08 inches). However, when switched to Turbo mode, it could partially clean a 4 mm (0.16 inches) slot. In Maximum mode, it handled the 4 mm (0.16 inches) slot even better. Finally, in Max+ mode, it was able to clean partially through 6 mm (0.24 inches) and even 8 mm (0.31 inches) deep crevices.

This shows a real improvement in suction power compared to older models, though it’s still debatable if the 18,500 Pascal is fully accurate. For comparison, the previous Roborock Qrevo S could clean a 10 mm (0.39 inches) slot with 7000 Pa. So, while Roborock has made progress, there’s still room to improve, particularly in terms of aerodynamic losses, though the new turbo brush design definitely helped.

Vacuuming

When it comes to cleaning debris on laminate flooring, the Qrevo Curv does a great job. It cleans the entire surface, even the corners, better than other models from the same line that have a retractable side brush.

I think this is thanks to the new side brush design. Overall, the robot does a fantastic job at sweeping, and the center and side brushes stay clean throughout the process. Kudos to Roborock engineers for this!

Protecting the brush from hair

Next up, we tested how well the turbo brush handles hair and wool. After spreading hair on the floor, the robot went to work, and some of the hair was collected into the dust bag. Interestingly, some hair did get wound around the turbo brush, but it seemed like most of it was thrown toward the center.

After a week of use in a home with both long-haired residents and a shedding dog, only a small amount of hair remained on the brush. Even then, it didn’t impact the cleaning performance, and the blades stayed clean. So, I’d say Roborock did a great job in this area too!

Carpet Cleaning

The Roborock Qrevo Curv does a solid job cleaning low-pile carpets. It also handles medium-pile carpets well after a few runs, thanks to the improved brush design and stronger suction power.

Self-Cleaning

After the “dirty tests,” I checked how well the robot self-cleans. After the dust bag was packed full, I returned the robot to its station and started the self-cleaning process. The result was impressive – the dust bag was completely cleaned, so this test passed with flying colors!

Mopping and Carpets

When it comes to mopping on carpets, the robot offers several modes. It can either avoid carpets entirely in mopping mode, gently drive over them, or make contact with the carpet to clean it. The most efficient mode is when it automatically picks up the wipes and even raises the body to avoid the carpet while cleaning.

Mopping

The mopping performance is top-notch. The wipes press firmly against the floor, absorbing dirt, and there’s no narrow strip left along the baseboard thanks to one wipe being able to extend to the edges.

Wiping Tough Dirt

When it comes to tougher stains, like dried coffee or sauce, the robot does a fantastic job scrubbing them out. It didn’t get it perfect the first time, but after seven passes, it managed to get everything clean, which is one of the best performances I’ve seen from a Roborock model. The best part? It didn’t even need detergent, so it passed the test with flying colors!

Washing quality of mopping pads

Let’s start with the station’s performance when it comes to cleaning the mopping pads. After some tough tests, I have to say, the mopping pads come out looking much better after being washed at the station. The water heating function really boosts the washing efficiency.

In normal use, after washing the floor, the wipes rinse out well at the station. Dirt doesn’t get stuck due to the pressure from the warm water, which is a big plus! Also, the drying process works well — the wipes are completely dry after being exposed to warm air at the station.

Station Maintenance

Although there are new scrapers in the tray, you’ll still need to clean the station by hand from time to time. Here’s the thing: Yes, the tray can be removed, but even with scrapers, large debris and hair tend to clog the filter, so you’ll need to rinse it out occasionally. Luckily, that’s easy to do. However, the ramp (the part that leads the robot into the station) isn’t removable, and it gets dirty over time. It’s a bit less convenient to clean, and it’s strange they didn’t make this part removable like in previous models.

Obstacle Clearance

As for crossing thresholds, it breezed past the 2 cm (0.79 inches) threshold. It struggles with a 3 cm (1.18 inches) threshold, and 4 cm (1.57 inches) was just too much for it. No matter how hard it tried, it just couldn’t get past that one. So while it does have great passability compared to other models, crossing a 4 cm threshold is unfortunately not something it can manage.

Passing Through Black Carpets

There’s no issue with the robot crossing black carpets. It moves right over them without any problems!

Volume

In terms of noise, the Roborock Qrevo Curv operates at a sound level of 59-65 dB depending on the cleaning mode. That’s actually pretty quiet for a robot vacuum, especially considering how strong the suction power is. When the station is self-cleaning, it reaches around 69 dB, which is still a reasonable level.

Personal Opinion

After a detailed review and testing, I gave the Roborock Qrevo Curv a score of 226 points, placing it second in the overall robot vacuum cleaner rankings. It almost took the top spot, but a few minor issues held it back.

Let me go over the pros and cons:

11. Can tackle tougher stains faster than other models.
12. Plenty of useful features in the app.
13. The option to remotely track your home via the robot’s camera.
14. Control via Hello Rocky voice assistant.
15. No issues with black carpets.
16. Low volume from both the robot and the station.
17. Quality build and high brand reputation.
18. Warranty and service availability.

Cons:

1. There’s no automatic detergent dispenser from a separate tank.
2. Power losses are still present, though less than before.
3. Object recognition doesn’t work well in the dark and needs improvement.
4. The ramp to move the robot into the station isn’t removable, making it harder to clean.

Despite these drawbacks, Roborock Qrevo Curv is efficient, easy to use, and highly reliable. It’s built by a trusted brand and works great in most situations, especially when navigating obstacles. If these issues don’t bother you, I definitely recommend it! I’ll be keeping it for a bit to see how it handles dirty floors long term, and keep you guys updated.
