Roborock Qrevo Curv test: The charming, but also effective, robot vacuum cleaner

Roborock continues to grow the difference between Qrevo robots and with the Curv introduces a station that is the complete opposite of the one that accompanies the S8 MaxV Ultra. Overall, it also introduces a new container organization useful for maintenance tasks: automatic emptying, automatic washing/drying and water filling.

The dust bag is integrated not under or next to the water tanks, but behind them, while the cover hides everything and extends the curves of the station. It ultimately looks like a little igloo, a bit futuristic with its line of LED lights.

Obviously, we leave it up to everyone to appreciate this design. From a more practical point of view, we note that this station is slightly deeper than average (45 cm wide and high) and that it does not have a power cable winding system. It is unfortunate that so much attention was paid to designing the station to allow the cable to pass freely alongside it, even if that was just a detail.

Robot-wise, the Qrevo Curv is a bit more traditional, or at least close to previous models with its circular shape, 35cm diameter and 10.3cm height, taking into account the distance scale built into the top for mapping. However, it is worth noting some new features, especially regarding the brushes.

The side brush ditches the usual straight strands in favor of two rounded back strands, while the center brush consists of two small rubber rollers held side by side to allow the hair wrapped around them to emerge directly into the mouth suction when it rotates. The side brush head design is also designed to prevent hair from rolling up and also prevents it from getting under carpets and prevents the robot from climbing on them.

As in the Qrevo Master and the latest S8, this brush head is also mounted on a robotic arm that allows the Roborock Qrevo Curv to extend to sweep along walls and into corners. In the same way, he can extend one of the two small mops designated for washing the floor, and he can also lift them to clean carpets without getting them wet.

As is now the case with most robots delivered with an automatic filling advance station, the water tank is not accessible. Only the dust container can be removed. If the station is responsible for emptying it, waste can get stuck there and the filter must be serviced.

The Qrevo Curv, an advanced robot, is equipped with sensors that allow it to move around the house (LiDAR, camera, shock, vacuum, etc.) and finally there are two buttons at the top. It allows you to start cleaning with the last used settings without going through the application, redoing it permanently or starting to empty the pool if the robot is at its station.

Contact and application

The Qrevo Curv works with the Roborock app and communicates via WiFi. We didn't find any major new features in this model, but it must be said that functionality was already complete with the latest models tested. Here again, they go beyond just home maintenance by using the Curv Camera to make calls or photograph animals at home.

We also find everything necessary for cleaning tasks: multi-floor mapping with room division and addition of restricted areas, adjustable suction power and water flow for each room, automatic carpet detection, obstacle detection with photo socket and automatic addition to cards, programming for the week… command It's all more responsive. In short, there are no complaints about this aspect of the Roborock.

If it doesn't give anything away, the Qrevo Curv Station hides as many bins and features as those found on previous models in the range, if not more. The bag allows you to empty the robot's dust container and two water tanks are provided to water and wash its mops if using its wash function. This washing is done using hot water (75°C, as announced by Roborock) and finished with a hot blast to speed up the drying process. In short, major maintenance tasks are done automatically and you can program the Qrevo Curv for a week without worrying too much.

However, be careful not to forget it completely. If the dust container is emptied, its HEPA filter retains approximately 2 grams of cocoa after our custom testing. Therefore, it risks clogging quickly and can reduce suction performance. The condition of brushes and mops should also be monitored, and it should be taken into account that the plant actually postpones maintenance tasks only with larger containers: 2.7 liters for dust and 3.5 liters for water tanks. They must also be emptied, refilled and replaced in the case of disposable dust bags.

It may also be useful to give the slope a little clean, which can accumulate dust and waste in the long run, even more than a mop washing area equipped with a mop system and ultimately not very visible in the lower part of the floor deep station. The tray can be removed if necessary.

As with all robots, many items can also wear out until they need to be replaced: brushes, mops, and filter. They are all easily accessible without tools, except for the screw-on side brush. We would have preferred not to need a screwdriver, as is the case with most models from other brands.

The Roborock Qrevo Curv uses heavy artillery to move around the house unobstructed: 360-degree LiDAR, lasers, camera… It also introduces a technology called AdaptiLift, which should allow it to lift itself up to overcome obstacles more easily, such as thick carpets Or threshold bars.

Overall, the robot performed well in our lab. It's even one of the best-performing models in our navigation test. It's right behind the Qrevo MaxV, but matches the performance of the SwitchBot S10 by picking up up to 75% more trash on the floor.

Once the mapping is completed, the rooms are cleaned systematically, without forgetting any free entry area. However, don't expect to see the robot pushing the curtains. And if things go well in the corners, waste may remain there despite the extendable brush head. Sometimes he “forgets” to draw the latter, but the result in the end is just a little better when he does.

The Qrevo Curv is a bit disappointing when it comes to detecting or avoiding obstacles. Even when the collision reduction option was set to the highest of the two available options, the robot ended up swallowing cables left on the ground. We've also seen it push other small hurdles that have been well explored. He is more careful about chairs, to the point that he avoids cleaning under them. Therefore, it is preferable to choose the lowest level to reduce collisions and arrange the house as little as possible. The Qrevo MaxV seemed more flexible to us. The Eufy X10 Pro Omni also does a little better with obstacles.
