The new Xiaomi Roborock S50 came on the market earlier this year. Proposed from around € 445, the robot vacuum cleaner second generation of the Chinese manufacturer has made a lot of people talking about it: it benefits from a very interesting tariff positioning combined with a formidable technical sheet. What will tickle the main actors of the sector? Probably. This aspi-robot connected in Wi-Fi embeds a laser range finder, offers 4 "modes" of aspiration (corresponding to 4 levels of power) and integrates in addition a water tank coupled with a mini-mop. More than just a garbage collector, the Xiaomi Roborock S50 can not only suck, but also clean (slightly) soils. for the loan of this product.
CONVENIENCE OF EMPLOYMENT:
In its perfectly rounded design, the Xiaomi robot vacuum cleaner looks somewhat like the iRobot models, the Roomba 696, for example. Topped with a laser rangefinder, like the Neato models, the Roborock S50 has a total height of 9.65 cm. Entirely lined with white plastic, this robot has three physical keys on its hood. The one on the left launches the "Spot" mode (targeted cleaning), the one in the middle triggers the aspiration or pauses it, and the one on the right orders the robot to return to its base.
One of the particularities of this robot lies in its cleaning function. By installing a mini mop (two are supplied with the robot) and filling the small water tank, the Xiaomi Roborock S50 can moisten the floor. Let it be said, there is no question here of replacing the weekly passage of the mop, but rather to remove the small, stubborn dust encrusted in the ground. This "bonus" function is rather well thought out and effective.
Mi Home connectivity and application
To use the features of the Roborock S50, it is essential to connect to the Wi-Fi network of the home. For that, you have to download the Mi Home app (iOS and Android). The application accompanies the user step-by-step in his configuration process. Be careful, however, it is not translated into French: users will have to be content with English. After connecting the robot in Wi-Fi to the smartphone, you must go back through the application to connect to the Wi-Fi network.
The Mi Home app is full of options. Some are basic but fortunately present, such as weekly programming of cleaning cycles, remote launch of the device, targeted cleaning or a specific area. After each pass, the application provides a fairly accurate map of the environment in which the robot has circulated. Virtual mapping is done in real time as the cleaning cycle progresses. At the end of a cycle, the user can access the cleaning summary, which lists cycle time, area cleaned, and remaining battery life. The history makes it possible to see the privileged or abandoned places by the robot.
It is also possible to create cleaning zones. To do this, simply draw rectangles within a map for the robot to go directly to the target area. In use, this function has proven to be extremely effective and practical, because it allows to create parts, but indirectly. The little extra that does not spoil anything: you can multiply the areas to be cleaned during the same cleaning cycle. The robot will be able to go and suck the floor of the room and the kitchen before returning to its base.
Another function should please the more geeks: the application can be used for remote control of the robot through a virtual controller. A gadget option that, let's face it, allows you to combine the useful with the fun.
Four " Cleanup Mode " are available from the application, corresponding to 4 suction power levels: "Quiet", "Balanced", "Power" average), "Turbo" and "Max" (maximum power). Except for an impact on the noise level, these different modes had no impact on the performance of aspirations that we will come back to later. The same goes for the "Carpet" mode, which automatically adapts the suction power when the robot passes over a carpet. On this function, again, we have not witnessed any major upheaval (positive or negative).
Another feature that we particularly appreciate: the one that reflects the state of the various elements of the robot vacuum cleaner. From the "Care" tab, the user can consult the level of wear of the filter, the main and lateral brushes, but also the sensors (11 sensors are housed on this device).
Finally, as mentioned above, the water tank and the mini-mop are mainly used to remove dust stuck to the ground after suction. They do not replace a real washing of the soil.
The small dust collector, with a capacity of 0.4 l, is easily accessible by simply lifting the hood. A little like the Neato vacuum cleaner (like the Botvac D5 Connected), it takes the form of a small cassette to extract, closed by an anti-allergenic filter that must be unclipped to empty the collector. The collector is not hermetically closed and has an opening particularly suitable for the fall of waste on the ground. It will therefore be particularly careful not to spill on the ground handling it.
A single main brush alternating bristles and rubber blades officiated on this vacuum cleaner, unlike some high-end robots that incorporate two (one rubber, one hair). The side brush, as on the Roomba 776p, is clipped and does not screw which is a good thing, as cleaning is easier.
Equipped with a rangefinder, the Roborock S50 is able to map its environment, to conduct a methodical navigation and manage obstacles. Like Neato vacuum cleaners, the Xiaomi robot systematically navigates in a zigzag pattern, during which it tends to lightly brush against obstacles. The vacuum cleaner cuts the pieces into zones, having first circumnavigated each piece before cleaning it. This methodical aspiration ensures a perfect surface coverage without the Roborock S50 going back to the same place several times. The system is precise, the surface coverage is impeccable.
The vacuum cleaner is also able to work in the dark, in dark areas or under furniture. He is a bit less comfortable in the corners where he struggles a bit to pick up all the trash. The robot always knows exactly where he is: he manages to get out of a labyrinth made of 16 feet of chairs and finds his base with a facility that always seems disconcerting. When his battery is low, he rejoins his base automatically to recharge, then resumes cleaning until he has finished.
The navigation system of the Xiaomi Roborock S50
When the Roborock S50 sees cables, he prefers to avoid them rather than face them and we can not blame him. However, we advise you to put a little order before each cleaning cycle. It does not go under our test coffee table or under a low sofa. On the other hand, he climbs on the carpets without hesitation, passes the thresholds of door and, thanks to his elevated wheels, he knows how to free himself from many situations. The only obstacles that may be problematic are those whose height reaches the level of the laser range finder; not knowing how to correctly estimate its own height, it tends to hang underneath.
This Xiaomi 2nd generation vacuum cleaner has been able to provide great suction performance, especially in normal mode ("Balanced") on hard floor and fine carpet. Indeed, on these two surfaces, the robot was able to recover respectively 95% and 93% of the test materials in 3 min, which is quite excellent. After 5 minutes and 20 seconds of cleaning, the Roborock S50 estimates that it has completed its task and returns to its base with 97% of the recovered waste.
On thick carpet with long hairs, it's a bit more disappointing. He managed to harvest 32% in 3 minutes and 40% after 5 minutes and 16 seconds, after which he returned gently to his base, believing that he had done the cleaning, as most of the rice grains found buried in the hairs of the carpet. The "Carpet" mode, supposed to modulate the suction power of the robot when it climbs on a carpet, was rather disappointing and absolutely did not improve the suction performance. So we manually turned on Turbo mode on thick carpet. The Roborock S50 then emits a higher sound level, but the results obtained with this mode are essentially the same as in normal mode: 35% of the waste sucked in 3 min.
Regarding noise, the Xiaomi Roborock S50 2nd Generation gets off with honors by reaching a noise level of 62 dB (A) in normal mode and 66 dB (A) in Turbo mode. These measurements are in the average average of robot vacuum cleaners of our comparative. The Samsung Navibot Corner Clean emits between 56 and 58 dB (A). Remember that this data has little impact, because the robot vacuum cleaner can work when no one is at home.
One wonders what substance this Xiaomi carbide! Here is an indestructible robot, which managed to hold not less than 2 hours 40 in normal mode ("Balanced") and 1 hour 36 in Turbo mode. The Roborock S50 2nd generation has enough to easily suck larger areas without having to recharge punctually. Allow 2 hours for a full charge. The Xiaomi Roborock S50 2nd generation is of course delivered with its base of recharge as well as two mini-mops to be able to humidify the soil at the request of the user. No remote control here, it's useless since the linked smartphone acts as a remote control. Physical Tag Point is not needed with the zone creation feature provided in the application. An additional filter is delivered with the device.
It is appreciated that the device has a li-ion battery, more durable than a NiMH battery. The battery is also removable and can be replaced if necessary.
