Roborock Qrevo Curv test: the charming, but also efficient, robot vacuum cleaner

Convenience of use

Roborock continues to cultivate the difference of Qrevo robots and offers with the Curv a station that is the polar opposite of that which accompanies the S8 MaxV Ultra. All round, it also introduces a new organization of containers useful for maintenance tasks: automatic emptying, automatic washing/drying and water filling.

The dust bag is integrated not below or next to the water tanks, but behind, while a cover hides the whole thing and extends the curves of the station. It ultimately looks like a small igloo, a bit futuristic with its line of LEDs.

We obviously leave it to everyone to appreciate this design. From a more practical point of view, we note that this station is a little deeper than average (45 cm in width and height) and that it does not include a power cable winding system. It is regrettable to have taken so much care with the design of the station to let the cable run freely next to it, even if it is only a detail.

On the robot side, the Qrevo Curv is a little more conventional, or at least close to previous models with its round shape and its 35 cm in diameter and 10.3 cm in height, taking into account the integrated telemeter on the top for mapping. However, some new features should be noted, mainly in terms of brushes.

The side brush abandons the usual straight strands for two strands rounded towards the back, while the central brush consists of two small rubber rollers installed side by side to let out the hairs that wrap around them directly into the mouth suction when they rotate. The design of the side brush head is also designed to prevent hairs from rolling up and also prevents it from going under carpets and prevents the robot from climbing on them.

As on the Qrevo Master and the latest S8, this brush head is also mounted on a motorized arm which allows the Roborock Qrevo Curv to extend it to sweep along walls and in corners. In the same way, he can extend one of the two small mops designed to wash the floor, and can also raise them both to vacuum the carpets without wetting them.

As is now the case with most robots delivered with a station offering automatic filling, the water tank is not accessible. Only the dust container can be removed. If the station is responsible for emptying it, it may happen that waste gets stuck there and the filter must be maintained.

A high-end robot, the Qrevo Curv is packed with sensors that should allow it to navigate around the house (LiDAR, camera, shock, vacuum, etc.) and there are finally two buttons on the top. They allow you to start cleaning with the last settings used without going through the app, to send it back permanently or to start emptying the collector if the robot is on its station.

Connectivity & application

The Qrevo Curv works with the Roborock app and communicates via WiFi. We did not find any major new features with this model, but it must be said that the functionalities were already very complete with the latest models tested. Here again, they go beyond house maintenance by using the Curv camera to make calls or photograph the animals in the house.

We also find everything necessary for cleaning missions: mapping of several floors with division of rooms and addition of prohibited zones, adjustable suction power and water flow for each room, automatic detection of carpets, detection of obstacles with socket of photos and automatic addition to the cards, programming for the week… The whole thing is more responsive. In short, no complaints about this aspect from Roborock.

Interview

If it doesn’t reveal anything, the Qrevo Curv station hides just as many containers and features as those of the previous models in the range, if not more. A bag allows you to empty the robot’s dust container and two water tanks are provided to supply it with water and wash its mops if its washing function is used. This wash is even done with hot water (75°C, Roborock announces) and ends with a hot blast to speed up drying. In short, the main maintenance tasks are automated and you can program the Qrevo Curv for the week without worrying too much.

However, be careful not to forget it completely. If the dust container is emptied, its HEPA filter retained nearly 2 g of cocoa after our dedicated test. It therefore risks becoming clogged quickly and could reduce suction performance. The condition of brushes and mops should also be monitored, and it should be borne in mind that the station actually only postpones maintenance tasks with larger containers: 2.7 l for dust and 3.5 l for water tanks. These must also be emptied, refilled and replaced in the case of disposable dust bags.

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

As with all robots, several elements can also wear out until they need to be replaced: brushes, mops and the filter. All are easily accessible without tools, with the exception of the side brush held by a screw. We would have preferred not to need a screwdriver, as is the case with most models from other brands.

Navigation system

The Roborock Qrevo Curv brings out the heavy artillery to move around the house without hindrance: 360° 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 comes in just behind the Qrevo MaxV, but matches the performance of the SwitchBot S10 by picking up up to 75% of trash on the ground.

Once the mapping has been completed, the rooms are cleaned methodically, without any free access area being forgotten. Don’t expect to see the robot push the curtains, however. And if it goes well in the corners, waste can remain there despite the extendable brush head. He sometimes “forgets” to draw the latter, but the result is ultimately only slightly better when he does so.

The Qrevo Curv is a little more disappointing when it comes to detecting obstacles, or rather avoiding them. Even when setting the collision reduction option to the highest level of the two offered, the robot ended up swallowing the cables left on the ground. We have also seen it push other small obstacles that were well detected. He is more careful with the chairs, to the point of avoiding cleaning underneath them. It is therefore preferable to choose the lowest level of collision reduction and to tidy up the house as little as possible. The Qrevo MaxV seemed a little more agile to us. The Eufy X10 Pro Omni also does a little better with obstacles.
