Roborock Qrevo Curv Robot Vacuum Review

The Roborock Qrevo Curv feels very well-built. Though its chassis is mostly plastic, it feels sturdy and solid. The top cover attaches with strong magnets that have no trouble keeping it in place, while the wheels, buttons, side brush arms, brushroll, and auto-empty dust flap are all rubber. Unfortunately, its dustbin is a hard plastic that could crack if you drop it. As for the finish, the top plate uses a glossy plastic with matte edges. Accessories like the mop pads and brushroll are easy to assemble and snap onto the vacuum's chassis; the side brush is the exception, as you need to use a screwdriver to attach it.

The Roborock Qrevo Curv has several components that require periodic cleaning, but they're mostly easy to access and service. Components like the brushroll, dustbin, vacuum filter, and mop pads are easy to remove, and cleaning them is simple, too. Thanks to its rubber material and two-part design, you can easily remove hair from the brushroll without scissors. While the dirt compartment self-empties into the base station, you may need to use a microfiber cloth to remove some remaining fine particles. Similarly, you can get away with tapping the filter inside a garbage can to release most of its dirt, but if you want to clean it thoroughly, you'll need to rinse it under water. The one pain point from a maintenance perspective is the omnidirectional wheel; you need to use a flathead screwdriver to remove it, and it's fairly difficult to lift out of its housing owing to the design of its axle.

Thankfully, the dock handles much of the day-to-day maintenance since it refills the vacuum's internal water tank, washes its mopping pads with heated water, and dries them. It also features a self-cleaning mop tray (though it's also easy to remove and manually clean if necessary). That said, this dock also has maintenance requirements. You'll need to dispose of its dirtbag, wash out the dirty water tank periodically, and refill its clean water tank.

For more information, see the User Manual and Maintenance Task Diagrams from Roborock's website.

The Roborock Qrevo Curv has high recurring costs as you'll need to replace parts frequently. As of December 2024, many replacement parts are not yet available through Roborock's website, though we assume they will be in line with previous Qrevo models.

• Brushroll: You'll need to replace the brushroll after 300 hours of use or every six to 12 months.
• Side brush: The side brush has a service life of 200 hours or approximately three to six months of use.
• Filter: The filter needs replacing after 150 hours of use, according to the maintenance tab of the companion app, or every six to 12 months per the user manual.
• Mop pads: You should replace the mop pads every one to three months.
• Multi-function dock dust bag: The dust bag has an advertised capacity of 2.7L. You can purchase replacements through Roborock's website.

The dimensions of the multifunction dock differ depending on the variant. For the exact dimensions and differences between models, refer to the Differences Between Variants section.

If you elect to purchase either the Roborock Qrevo Edge or Curv with Refill and Drainage, Roborock has additional space requirements to accommodate the water and drainage lines; see these diagrams from Roborock's website of the Curv and Edge's space requirements for more information.

The Roborock Qrevo Curv's internal dustbin can hold more than its other Qrevo siblings, like the Roborock Qrevo Pro, but it'll still need to return to the multifunction dock to self-empty at the end of almost every cleaning session. There's no fill sensor; instead, you'll get regular reminders on the Roborock companion app to check the dustbin.

The Roborock Qrevo Curv's multifunction dock can self-empty into disposable 2.5L dirtbags and has a pair of water tanks: one 4L clean water tank that refills the unit's internal water tank and also washes the mopping pads, and a second 3.25L dirty water tank for wastewater from the mop washing process. The Edge variant has larger tanks that will hold more.

If you opt for the Refill and Drainage variants, there are no internal tanks, as they use water and drainage lines for clean and dirty water. They also have a small detergent tank to create a cleaning solution for mopping. The Curv model features a 550 mL detergent tank, while the Edge has a 600 mL tank.

Like the Roborock Qrevo Pro's docking station, this model's base station heats the water to clean and sanitize the mop pads and also uses warm air to dry them; this base station has a higher advertised water temperature of 167 °F (75 °C) for a better clean.

This vacuum returns to its base station for charging once it has less than 14% remaining battery life. It also features an 'Off-Peak Charging' function, which only allows the vacuum to recharge during off-peak hours for power demand to minimize electricity costs. You can keep track of the vacuum's battery status by checking the indicator light on the top, which changes color and pattern depending on the current charge status.

The Roborock Qrevo Curv is a feature-rich robot vacuum. Like the older Roborock Qrevo, it has an Auto-Mop Lift feature to raise the mop pads on carpeted surfaces to run vacuuming and mopping jobs within the same cleaning cycle. The system lifts the mopping pads by 10 mm on the Curv instead of the older Qrevo's 7 mm. That said, there are also some unique features for the Curv and Edge models. First is implementing the FlexiArm system on the side brush instead of just on the mop, like on the Roborock Qrevo Pro. This allows the side brush to have better access for clearing debris or mopping along walls and traditionally tough-to-reach areas for robot vacuums with a circular design, like in corners. Another new addition is the AdaptiLift chassis itself. It independently adjusts the height of the vacuum's three wheels to find the optimal angle relative to obstacles, allowing it to traverse common obstructions like room thresholds up to 4 cm in height.

There are a variety of carpet-specific cleaning functions. Carpet First mode sends the vacuum to clean carpets before anything else in its cleaning cycle to prevent them from getting wet, and the Deep Carpet Cleaning mode cleans carpets twice while using a higher suction power level setting. You can also run the Avoid mode to bypass carpets entirely while cleaning or employ the Ignore mode so the vacuum disregards its carpet protocols, instead engaging its mopping function. You can manually select five different power level settings and two different vacuuming route modes.

The mopping options are just as granular, as you can choose between three water flow level presets (Low, Medium, and High) or select the Custom mode to choose from 30 different water flow increments. The route mapping settings allow you to choose between four modes, depending on whether you need a Fast, Medium, Deep, or Deep+ clean.

The SmartPlan AI system allows the vacuum to automatically select the optimal vacuuming and mopping modes for different rooms, as well as plan the optimal cleaning route.

This vacuum features an updated AI Reactive Tech system with an RGB-color camera-based system that functions in light and dark settings. It will also use this system for its other camera-based features, like Remote Viewing, which allows you to see what the robot vacuum sees in real time or to find your pet and initiate a video call with them.

Finally, the Curv and Edge feature a voice assistant named Hello Rocky. You can use the voice assistant to change various settings on the fly; see the app's settings for more information.

The Roborock Qrevo Curv delivers outstanding pick-up performance on hard surfaces. Regardless of size, it can clear the vast majority of debris in a single pass. Corner and wall performance is also fantastic, as its FlexiArm system extends the side brush to offer more coverage and improve pick-up performance in corners than traditional robot vacuum with a circular design. Turning off the Less Collision Mode, which avoids contact with walls or furniture, further improves the pick-up performance. While turning off this setting helps deliver industry-leading performance, it comes at the cost of making contact with and rubbing against your walls and furniture, so it may not be for everyone.

The Roborock Qrevo Curv does a decent job clearing debris from high-pile carpets. It has no trouble dealing with medium- and large-sized debris, like rice or cereal, though you might need to run another cleaning session to clear away finer debris like sand caught deep in the carpet fibers. The FlexiArm system doesn't work as well on carpet as on hard surfaces, so corners remain a pain point like on other robot vacuums with a circular design.

The Roborock Qrevo Curv is adequate for cleaning low-pile carpets. It can clear most medium to large debris, like rice or cereal, in a single pass, although the side brush tends to toss some debris around. Fine debris, like sand, is a challenge, as the vacuum lacks the suction power to effectively lift it from the carpet fibers even when using the Carpet Boost function that automatically increases suction strength on carpets. Like on high-pile carpets, the FlexiArm system doesn't improve pick-up performance in corners.

The Roborock Qrevo Curv delivers acceptable pet hair pickup performance on low-pile carpeting. It can clear hair lying on top of carpeting but can't agitate the carpet enough to release strands deep in the fibers; you'll likely need to run several cleaning cycles if you have pets that shed heavily.

The Roborock Qrevo Curv's suction force isn't very strong, as its suction inlet sits too high above the contact surface to generate a tight seal on bare surfaces, resulting in low suction power measurements.

The Roborock Qrevo Curv's airflow performance is good overall for a robot vacuum. It's sufficiently powerful to lift heavier debris, though it may be a bit inconsistent.

The Roborock Qrevo Curv is remarkably quiet. You'll hear what people nearby say even when the vacuum runs in its most powerful suction mode.

The multifunction dock is louder than the vacuum when using the self-empty function with a peak volume of 64.8 dBA. The default Voice Assistant volume is also quite loud, reaching 64.3 dBA. You can adjust the volume through the Roborock app.

While the Roborock Qrevo Curv does a decent job maneuvering, many navigation and obstacle avoidance features produce intermittent results. Cleaning under furniture that sits high off the ground, like couches, is no problem, and the vacuum effectively navigates around furniture legs with space permitting. However, owing to the added height of the built-in microphone for Voice Assistant functionality on the LIDAR sensor, it struggles to clean under lower furniture like an entertainment console.

This vacuum features an "AdaptiLift" system that dynamically adjusts its floor clearance and positioning to navigate obstacles by individually lifting its wheels. Unfortunately, this system works inconsistently; the vacuum still gets stuck on surfaces like shag carpets or rugs with tassels. Using different obstacle avoidance modes, like Pet, doesn't help the chassis lift when encountering high-pile carpets, nor does following Roborock's recommendation of adding the mop pads.

Similarly, the vacuum's obstacle detection isn't particularly effective at assessing hazards—it can recognize thicker, shag-pile rugs as objects to react to (although the AdaptiLift system doesn't help) while not recognizing things like electrical cords, which it can get stuck on.

The Roborock Qrevo Curv performs notably better than previous models like the Roborock Qrevo Pro and does a decent job of sealing in fine particles. However, some fine particles escape from around the vacuum's body, and it lags behind comparable models like the iRobot Roomba S9, which uses an onboard HEPA filter to seal in fine allergens.

Like most robot vacuums, the Roborock Qrevo Curv struggles with debris in cracks and crevices. Its side brush tends to drag debris outwards instead of directing it toward the suction inlet, which itself is too high above the ground to form a seal and generate sufficient suction. Running the vacuum in the 'Max+' suction mode produces similar results.

The Roborock Qrevo Curv's stain-clearing performance is among the best on the market, even slightly outperforming its other siblings from the Qrevo line-up. When using the High water flow mode with the pathing set to Deep+, its rotating mop pads scrub away dried-on stains, and the FlexiArm extending mop design allows for more effective cleaning along walls and corners than most conventional hybrid vacuum/mops. Another improvement comes from the vacuum's Re-Mop feature, which uses the built-in camera to detect stains and dedicate additional cleaning passes to them. However, as you can see in this video of a second clean cycle, this feature is inconsistent.

The new multifunction dock's mop-washing process is impressive. After mopping, the vacuum returns to the dock to clean the dirty pads with 167 °F (75 °C) water before drying the clean pads with warm air. If the mops aren't sufficiently clean, the dock will initiate its Re-Wash feature.

The Roborock Qrevo Curv isn't designed to pick up water; its mopping pads can soak up a bit of water, but getting the vacuum to suck up water will likely damage it.

The Roborock Qrevo Curv has many physical automation features. Its multifunction dock eliminates much of the day-to-day maintenance requirements that come with a robot vacuum, as it empties the vacuum's dustbin, refills its water tank, washes its mop pads with heated water, and dries its mopping pads.

There are two physical control buttons that you can use to perform basic functions without having to use the app. Pressing and holding the Power button turns the robot vacuum on and off, while a single press starts a full cleaning cycle. Pressing the Dock button while the vacuum is cleaning sends it back to its base station; pressing the Dock button while docked will manually empty the dustbin. Finally, pressing and holding the Dock button while in the base station initiates a spot clean session, where the vacuum cleans a small area around itself; pressing and holding the Dock button while in the base station washes the mops.

The Roborock app is feature-rich and has a fairly intuitive interface.

The app allows you to see the robot vacuum's path in real-time, as it creates a map of your home. You can also create multi-floor maps of your home for up to four floors, set up no-go zones, establish cleaning zones for spot cleaning, reconfigure and name areas, manually set the surface type for each area, set the suction and mopping modes, and customize the order the vacuum moves through each room. You can also set Entrapping Areas, which slow down the vacuum to minimize damage on delicate surfaces like door thresholds and steps.

There are many Obstacle features as well. The Less Collision modes avoid contact with walls or furniture (scanning is less precise as a result), the Pet mode enables better animal waste detection, and the Reactive Obstacle Avoidance allows the vacuum to respond in real-time to obstacles. There are also a few new features for the Roborock Qrevo Curv: Obstacle Photos takes photos of identified objects so you can view them from the app, while Pet Snaps takes pictures of your furry friends that appear as a paw icon on your house map.

Another new feature set is the Remote Viewing sub-menu. The remote viewing function allows you to control the robot vacuum and see a live view of what it sees. You can set up a password so only someone with the password can use the feature. You can also use this function to send the robot vacuum to find your pet and start a phone call with them via the vacuum.

The Maintenance sub-menu gives you a projected service interval for the filter, brushroll, side brush, sensors, and mopping pad, while the Voice Assistant sub-menu allows you to customize related settings.

There are also quite a few configuration options for the multifunction dock. You can adjust the frequency of mop-washing cycles, the intensity of mop-washing, and the length of the mop-drying cycle. Depending on the size of your home, you can also adjust how often the vacuum will return to its dock to self-empty or simply leave it up to the vacuum itself.
