The modern robot vacuum cleaner has become an indispensable tool for keeping clean. Xiaomi Mijia is known for its reliability, intelligent navigation and affordable price, making it one of the most popular on the market. However, for the technology to work for years and really make life easier, it is important to understand the principles of its operation and rules of operation.
The first time you've seen a device, you've often wondered how to connect to Wi-Fi, why you need so many sensors, and why it sometimes stops in the middle of a room. In this article, we'll look at all the nuances of use, from unpacking to deep-tuning the scripts in the app, and you'll learn how to make a smart home work for you, not the other way around.
It’s important to note that most models, whether Roborock S5, Viomi V2 or Mijia 1S, have similar control logic. The main control center is the smartphone, but the basic functions are available without it.
Initial preparation and unpacking of the device
After removing the box from the transport package, do not rush to turn on the device immediately. Inside, in addition to the robot itself and the charging station, you will find a dust container, a block with a large number of different components. HEPA-The first thing you need to do is to remove all the transport locks, which are often painted bright orange or blue, and if you forget to remove those, the motor can be overloaded or the sensors will give false readings.
The next step is to install a side brush, which is simply pressed until you click it, and notice the shape of the seat, and the brush has a specific protrusion that should match the groove on the bottom of the robot, and then you try to spin the brush a little bit with your finger, and it should rotate freely, without jamming, and that's a key element for cleaning along the boards.
⚠️ Warning: Before installing the main container, be sure to remove the protective film from the dust collector filling sensor. If you do not, the robot will constantly report an error of the full tank, even if it is empty.
The charging station requires proper placement. To operate properly, the navigation and docking system needs a free space of 0.5 meters on the sides and 1.5 meters in front. Don't place the base in niches or between the legs of heavy furniture. The Lidar laser rangefinder on the upper tower must have 360 degrees of unobstructed view to build an accurate map.
☑️ Check before the first launch
Connecting to the network and setting up Mi Home
Xiaomi’s digital ecosystem is based on the Mi Home app. To get started, you need to create an account and add a device. Click the + button in the upper right corner and select your region. Importantly, if the robot is not, try changing the region in the app settings to China, as many models come with Chinese servers.
The pairing process requires care. Make sure your smartphone is Bluetooth enabled and geolocated. The robot is paired by simultaneously clamping two buttons on the body (usually an on button and a home return button) until the Wi-Fi indicator lights up. The app will suggest you enter a password from your wireless network. It is critical that the router distributes the network in the 2.4 GHz range, since the robot modules do not support the 5 GHz standard.
Once successfully connected, the device will automatically update the firmware, which can take 5 to 20 minutes, while the robot can make sounds, spin lidar or change the color of the indicators, and you can not interrupt the update categorically, which can lead to the "bricking" of the device and the inability to connect to Wi-Fi in the future.
In the device settings in the application, you can name the room where the base is located and configure voice packets. For Russian-speaking users, you often need to manually download Russian in the Voice Package menu, selecting the appropriate option in the device settings.
Basic cleaning and management regimes
The application interface gives you complete control over the cleaning process. The home screen displays the current map, battery status and container filling level. The Start button triggers automatic cleaning of the entire area that the robot has already explored or explored in real time.
There are several basic operating modes that can be selected depending on the type of pollution:
- 🧹 Quiet mode – Minimum noise, suitable for working at night or when you are at home, but suction power is reduced.
- ⚡ Standard mode – optimal balance between noise and efficiency for daily cleaning.
- 🌪️ Turbo mode – maximum power for long-pile carpets or heavy contaminants, but runs very noisy.
- 💧 Wet cleaning – activates the water supply (if a module with a tank is installed) and reduces the suction power.
Spot Clean is also available, and when it is activated, the robot starts spiraling around 1.5 meters from the launch point, ideal for eliminating spilled cereals or sand in one particular area.
💡
Use Do Not Disturb mode in the app so that the robot doesn’t turn on or voice messages at night or during your lunch.
For more complex tasks, you can divide the map into rooms, and once you've built the full map, you can edit it in the app, combine zones, create virtual walls or no-go zones, and no-go zones, which prevents the robot from going to fringe mats or going up to the second floor of the stairs.
Working with maps and virtual restrictions
Navigation based on Lidar or VSLAM allows you to build detailed maps of the room. After the first general cleaning, the map is stored in memory. In the Map menu, you can rename rooms, which is convenient for voice control through Alice or Google Assistant (for example, "Alice, let the robot wash the kitchen").
One of the most useful features is to create no-go zones, so you can draw a rectangle or a line on a map where the robot won't go, and that's for protecting the wires on the floor or the areas where the animal water bowl is, and the lines are drawn directly across the smartphone screen.
| Type of restriction | The shape on the map | Appointment |
|---|---|---|
| The no-go zone | Square/Rightangle | Complete prohibition of entry (carpets, wires) |
| Virtual wall | Line | Barriers that cannot be crossed (thresholds, stairs) |
| No cleaning area | Circle/Zone | Ignoring a specific area during general cleaning |
If you rearrange furniture or change layout, the card can be saved as a backup or removed and rebuilt. To reset the card, you need to go to the map settings in the application and select the option “Reset the card” or “Move the base” if the robot is lost.
⚠️ Note: When moving the robot to another room (for example, to another floor), be sure to bring a charging base with you. The robot must "see" the base in a new location to correctly update the map or create a new one.
Maintenance and cleaning
The durability of the device depends on the regularity of maintenance, and it is recommended to empty the main dust collector after every 2-3 cleanings, even if it is not fully filled, this prevents the formation of dust inside the engine compartment.
Filters require special attention. HEPA-The filter (thin cleaning) can not be washed with water - it can only be gently knocked out or cleaned with a dry soft brush. Washing with water will lead to the adherence of the fibers and a fall in motor traction. Pre-filter metal cleaning nets can be washed under the tap, but must be completely dried before installation (at least 24 hours).
How often do you change your bills?
Sensors are the eyes and ears of the robot. Once a month, wipe with a dry microfiber:
- 👁️ Collision sensor (front bumper).
- 📡 Height difference sensors (below, at wheels).
- 🔋 Charging contacts (on the robot and on the base) – oxidation of contacts can cause the robot to not charge.
- 🌪️ The hole of the air intake and the laser rangefinder itself on the tower.
The main brush also needs cleaning, and often has hair and wool on its ends, which puts additional stress on the engine, and use a kit knife or nail scissors to gently cut and remove the wound fibers.
Frequent Problem Solving and Error Codes
Even the most sophisticated systems sometimes run into difficulties, and the robot has a self-diagnosis system that reports problems with voice or flashing indicators, and the app also duplicates those messages.
Let’s look at the most common error codes and methods for eliminating them:
- ❌ Error 1 (Laser block clamped) – check if the object is stuck to the rotating lidar tower.
- ❌ Error 2 (wheels clogged) – flip the robot, check the side brush and main wheels for debris.
- ❌ Error 4 (Ground wheel jammed) - often occurs if the robot is stuck on a doorstep or carpet.
- ❌ Error 10 (Dust filter is clogged) - remove the container, clean the filter and blow out the compartment.
💡
90% of errors are due to mechanical obstructions or sensor contamination, and before you carry your device to the service, thoroughly clean all moving parts and sensors.
If the robot loses Wi-Fi connection, try rebooting the router. In rare cases, resetting the robot's own Wi-Fi module (clamping the buttons to the beep) helps, and check if the router is too far from the base site - the signal must be stable.
