overcomes obstacles, reaches out to sweep edges and hair doesn't get tangled

Los Robot vacuum cleaners have become one of the most popular cleaning methods in Europe. The hustle and bustle of personal obligations and marathon work days make balancing household chores a personal hell in most homes. However, these types of devices manage to alleviate a significant part of this workload, mainly in the daily maintenance of the floor.

Among the brands that have this type of vacuum cleaner is Roborock, which has specialized for years in everything related to home cleaning and also offers portable models. At EL ESPAÑOL-Omicrono we were able to test the Roborock Qrevo Curv (1,499 dollars), one of the most recent additions with the most advanced technology that took care of the housework for the last few weeks.

More than a new version or a minor update, Roborock wanted rethink certain essential technological issues that had been identified as problems or gaps in the history of robot vacuum cleaners. For example, they completely modified the brush systems so that hair tangles much less while an extendable arm removes dirt from corners.

Brushes and vacuum cleaner

When assembling the robot vacuum cleaner, the first thing that stands out is that the central roller, the most oblong which is placed in the belly of the device, It is composed of two pieces in the Qrevo curve. In other devices, this space is occupied by a single rubber cylinder which will be responsible for transporting the dirt to the suction mouth.

The two pieces are placed next to each other and rotate in different directions. With This prevents longer hair from tangling. and damage the part when using the device. Additionally, Roborock inserts plastic bristle brush strips to further improve dirt collection.

One of the traditional problems with robot vacuums is tangling. The resistance of the hair can even cut the blades of the central barrel brush, reducing efficiency and, ultimately, They forced the user to buy a replacement with a certain frequency.

Another novelty integrated into the Qrevo Curv is the FlexiArm brush, one of the technologies that Roborock integrates into some of its most advanced vacuum cleaners. It's a asymmetrical arc-shaped brush that extends from inside the frame when it is necessary to accelerate the suction as much as possible.

For example, in corners or on the edges of walls. Areas that other models cannot reach due to their size and which leave accumulated dirt that requires human intervention. Something that happened with the previous robot we had at home.

Concerning the suction power, Roborock says it has 18,500 Pa of suction in the most advanced settings. From a daily point of view, we notice that it manages to extract a greater amount of dirt in a single pass, although for a slightly less thorough cleaning you can choose less demanding suction settings that lengthen the autonomy and generate less noise.

In practice, the 18,500 Pa announced by the manufacturer can prove useful when it comes to cleaning carpets – the most complex scenario possible – or when you have not vacuumed for several days . It can also be used in addition to deep cleaning dayswhere dust and lint move freely from the most unexpected places.

All-terrain cleaning

The second part of this device's job is cleaning floors. Traditionally, this phase is the weakest for robot vacuum cleaners, although thanks to the latest advances, the improvement is very significant and is evident with the Qrevo Curv. The big change was brought by mops with different types of vibrations which managed to remove embedded dirt and not just soak the surface.

Roborock, in the Qrevo Curv, takes it to the next level with the incorporation of a system of two rotating circular mops which has some lateral movement. As with the FlexiArm brush, the areas closest to the wall were not cleaned in previous models, but now the cleaning is almost complete, although the corners where it is still not possible to reach remain pending.

The two circular mops it equips are rotating and manage to remove the most encrusted dirt. Actually, I think They are made from a more durable material than previous models which I tried at Roborock and they had a single vibrant fabric.

This robot vacuum cleaner also incorporates a three-part suspension system —one in the front and two in the back—which use a lift attached to the wheels to improve movement inside the house. This is a double-edged sword, as it can overcome obstacles such as high-pile carpets or height differences of up to 4 centimeters.

The worst part is that the robot can go directly to the terrace. Before discovering this feature, I found myself with the vacuum cleaner in the middle of the garden vacuuming it. The adventure was short-lived and, in reality, the fault was not correctly configuring the plan of the house by placing virtual barriers.

Should I buy it?

Autonomy is sufficient for an average floor of around 90 meterstaking into account suction – in normal mode, not turbo – and scrubbing in a single pass. For charging, the Qrevo Curv has a parking base that looks more like a garage than a traditional charging base.

The robot vacuum cleaner is almost completely integrated inside. The base is large, although the design is subjectively elegant and At first glance, it doesn't look like a device.. Inside there are two tanks – clean water and dirty water – and an additional compartment with a bag to collect dust.

This distribution indicates that the Roborock It is capable of emptying and cleaning itself independently. It completes the first task quickly and surprisingly quietly compared to other robot vacuums I've tested. For the second, the company integrated a new mop cleaning system that reaches 75 degrees Celsius, which eliminates almost 100% of bacteria.

THE Roborock Qrevo Curv is available for 1,499 dollars on Amazon. Thanks to its technology, it manages to go where others go simply because they do not have a brush or fold-out mop; achieving a very good result in daily cleaning. In addition, automatic emptying and cleaning make us completely forget about maintenance, a task which can sometimes be tedious.
