Box contents
Start up
As usual, The robot comes partially charged, but it is advisable to charge it completely before using it for the first time. The battery is a old acquaintance of the robots from the Xiaomi universe, a lithium battery with a large capacity, 5.200 mAh, which provides an autonomy of between 150 and 220 minutes and takes between 4 and 5 hours to charge.
In this case, The charging base is incorporated into the dust collector itself, and includes a screen that shows the robot's charge percentage, as well as other informative icons (for example, indicating that the dust bag must be removed).
The robot can be operated in multiple ways, both with the buttons on the top, as well as through voice commands and through the app, although It will be through the application that we will have access to all the advanced functions it includes.
Installing the app
The Viomi S9 can be handled through the well-known Xiaomi Mi Home app. To do this, install the application and create an account, if you do not have one.
Then, you can search for device, or we go to home appliances and select “Viomi S9”. When performing this first configuration process, It is advisable to have the robot and the mobile phone close to the router, to facilitate connectivity.
The frequency must be 2,4 GHz, so if your router is dual, you should take it into account and choose this one and not the 5 GHz one (which will say 5G or something similar).
Thanks to the app we will enjoy greater comfort and versatility when operating the robot, having access to a wide variety of functions and being able to control it whenever we want and wherever we are: on the street, at work, in a cafeteria... This way, we will always have a clean house when we return.
Viomi S9 operation
This high-end robot vacuum cleaner offers a advanced feature set that puts you at the forefront in many aspects, offering excellent overall performance.

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.
The Viomi S9 has 4 power levels (Quiet, Standard, Medium and Strong), so we can choose the most appropriate one based on the degree of dirt to optimize cleaning, battery life and noise level (at the lowest levels, it is quite quiet) .
Navigation
Another highlight of this robot is its smart navigation. Its 2.0º LDS 360 laser sensor has a range of 8 meters and a frequency of 2016 Hz, which together with its multiple sensors (anti-shock, anti-fall, etc.) provide very fluid and efficient navigation.
LDS Sensor Detail
The laser allows you a High precision in mapping and movements, in addition to predictive navigation —since it anticipates obstacles— and the possibility of cleaning in dark conditions (a situation in which robots with camera-based navigation have difficulties).
In addition, 360º laser scanning prevents the robot from getting stuck when it has to get under furniture, previously calculating the height to estimate if you can enter and exit comfortably.
In this way, the Viomi moves quickly and efficiently, reaching 100% of the home surface and cleaning in less time than other robots, with a cleaning speed that is around one square meter per minute or even more.
Brushes
The Viomi S9 has a side brush, as is common in many high-end devices. This is because thanks to its advanced technology, the robot always knows what situation it is in, where it has cleaned and where it has not, so you don't need two brushes, you know exactly what to clean.
Moreover, The central roller combines bristles and rubber in a studied design to achieve excellent cleaning on both hard floors and rugs and carpets. It offers a very similar appearance to other devices in the Xiaomi ecosystem, with good quality and a high density of bristles.
Deposit
The mixed tank of the Viomi S9 of 300 milliliters for solid dirt (250 milliliters for water). This capacity is sufficient, taking into account that given its great suction power, it compacts quite a bit, and the robot is also emptied into the discharge base each time..

The replacement bags cost about 3-4 euros per unit, which It is not an excessive cost, considering the comfort they provide (and it's more affordable than other self-emptying robot vacuum cleaners).
Scrubbing for a more thorough clean
The S9 has a mixed tank for solid dirt and liquids, which makes it possible for the robot to vacuum and mop at the same time. It includes an accessory to put the mop that is inserted under the tank, and offers two options:
Detail of the antibacterial disposable mop
The S9 makes a Y-shaped movement when scrubbing, which in a certain way imitates what people do when scrubbing, passing over the same place more than once, achieving a better result than robots that simply wipe the wet mop as they move.
Viomi's robot It has electrical control of the water flow, so that we can select between three scrubbing levels to adapt it to the type of floor and the degree of dirt: low, for wooden floors or light dirt; medium, for day-to-day cleaning; and high, for situations in which we need a more thorough cleaning.
