Its large 5.200 mAh lithium battery, together with optimized energy management, provides you an autonomy of the largest on the market, up to 210 minutes, allowing you to clean large rooms with a single charge.
If that is not enough, there is loading and continuation available., so it returns to the base and once charged, resumes cleaning to finish it.
The automatic suction station should be located in a place where the robot has enough space to move and attach to it without problems (as orientation, half a meter free on each side and one meter forward), although thanks to the high precision of its movements, this is not strictly necessary.
The base includes various indicators to inform us aspects such as the state of the collector, whether the bag is full or the battery level.
The Viomi Alpha UV S9 can be operated through the buttons on its top, although It will be through the mobile app that we will get the most out of its advanced functions..
Installing the app
The app to manage this robot is the well-known Mi Home from Xiaomi, available for iOS and Android. Once installed on your mobile and created an account, if you do not have one, you simply have to follow the instructions, in a simple and intuitive way.
The connection must be carried out via the 2,4 GHz frequency, so if your router is dual, you should pay attention and choose this one and not the 5 GHz one, which will say 5G or something similar.
Once connected to the mobile, we can operate the robot comfortably, whenever we want and wherever we are (from work, on the street, in a cafeteria...), which provides us with great comfort and versatility.
To access the various functions it is necessary to have a home map, so The first thing we will do once loaded is start the robot from the base, leaving the doors of the rooms we want open to have a map.

Smart navigation
Its LDS 2.0 laser sensor offers better performance and great precision, which, together with the multiple sensors (anti-shock, anti-fall, etc.), provides you with a fluid, efficient and orderly navigation.
Additionally, the laser has a range of 8 meters, giving you a predictive navigation that allows you to map faster and anticipate obstacles, as well as navigate in dark conditions, unlike robots with camera-based systems.
360º scanning also allows you perform better in complex environments, such as the area between the legs of chairs or under furniture, effectively avoiding obstacles but avoiding getting into trouble.
In this way, the Viomi Alpha UV S9 covers 100% of the home surface quickly and fluidly, with a cleaning speed of around 1 square m2 per minute or even more.
Power
The Nidec brushless motor, of Japanese origin (common in Xiaomi ecosystem robots), together with a studied design of the air flows, allow the Alpha UV to reach the 2.700 Pascals of power, a very high figure that allows you to do great work on all types of surfaces.
This high absorption capacity places it above other prominent and successful members of the Xiaomi universe.and Roborock S6 Max V or Xiaomi Vacuum 1C, which reach a remarkable 2.500 Pa.
As usual in high-end robots, Automatically increases power when it detects you are on carpet, for a deeper clean; In addition, it is capable of overcoming obstacles of up to 2 centimeters, so carpets of a certain thickness are not a problem.
Brushes
Like other high-end models with smart navigation, the Viomi Alpha UV S9 has a single side brush; This is because thanks to this technology, the robot always knows where it is, where it has passed and where it has not, so it does not need two brushes.
The rotating central brush offers good performance on both hard floors and rugs and carpets, combining rubber and bristles to effectively trap all types of dirt, dust, hair, crumbs and other particles.
As we have seen in other models from the Xiaomi universe (such as, for example, the wonderful Roborock S7), The Viomi Alpha UV brush is floating, which allows it to stick more to the ground, adapting to the type of surface to always achieve the best result.

One of the star features of this robot is the dirt storage section. Its mixed tank does not offer an excessively large capacity for powder - 300 milliliters - but it is sufficient, since The Alpha UV S9 has a self-emptying base that allows you to empty the dust into a bag.
This system is extremely comfortable and hygienic for the user, who no longer has to no need to worry about dirt for weeks. The 2.0 design of the self-emptying base, with a straight air duct design, allows the emptying process to be faster, avoiding blockages.
The bags have a capacity of 3 liters, so they can last approximately a month, They have a self-closing system that makes their collection very hygienic, without clouds of dust, making it a perfect technology for allergy sufferers.. In addition, both the app and the base itself notify us when the bag is full and it is time to change it.
For its part, Its triple filtering system effectively traps microparticles of dust and mites inside the device., avoiding secondary pollution and achieving a cleaner environment.

The ones we have seen so far are shared with a very similar model, the Viomi S9, but the Alpha UV includes, as its last name indicates, sterilization using ultraviolet light to achieve maximum cleanliness and hygiene.
Ultraviolet light can effectively kill viruses, bacteria and other germs, a system that until now we knew in upholstery cleaners (like the famous Hoover Ultra Vortex UV) and that we had only seen in another robot vacuum cleaner, the Amibot Pure Laser.
The ultraviolet technology of the Viomi Alpha UV allows you to effectively kill 5 types of bacteria (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus pyogenes and Salmonella aertrycke); The UV lamp turns off when the robot is stopped, so as not to use it unnecessarily.
Its effective technology, tested by prestigious laboratories, achieves a 99,99% effective in eliminating these germs, achieving greater hygiene and health protection.
Added to this ultraviolet sterilization system is the scrubbing incorporated by the robot, which in addition to the usual microfiber mop, includes disposable mops with antibacterial components.
