Changing internet providers, buying a new router, or simply updating your wireless network password are common situations faced by every owner of smart devices. For robot vacuum cleaners Xiaomi This event means the connection needs to be reconfigured, as the device can't automatically adjust to new network settings without your intervention. Simply changing the router settings will cause your smart assistant to lose connection to the server, stop generating maps, and stop being controlled from your smartphone.
The reconnection process may vary depending on the device model and the version of the installed software. Some modern models automatically They offer to change the network when a familiar SSID is detected, but in most cases a manual reset of the Wi-Fi module is required. It's important to understand that most robots Xiaomi And Roborock operate exclusively in the range 2.4 GHz, and attempts to connect them to 5 GHz are doomed to failure.
In this article, we'll cover all the steps involved in changing your Wi-Fi network: from preparing your equipment to the finer points of setting it up through the app. Mi HomeYou'll learn how to avoid common pairing errors, why indicator lights are a certain color, and how to properly reset the communication module so the robot can resume cleaning on schedule.

Preparing to reconnect the device
Before you begin setup, you need to ensure your infrastructure is ready to accept a new device or reauthorize an existing one. The first step is to test your router. Make sure the network 2.4 GHz is active and broadcasting. Even if your router is dual-band and combines networks under a single name, for the initial setup Xiaomi It is often necessary to temporarily separate network names (SSIDs) or turn off the 5 GHz band during pairing.
It is also critical that the smartphone from which the setup will be performed has geolocation (GPS) and Bluetooth enabled. Operating systems Android And iOS require access to geolocation to scan for available Wi-Fi networks, which is a prerequisite for the device discovery protocol to work in the application Mi Home.
Check the robot vacuum's charge level. The reconnection process and possible firmware update after changing networks may take time. We recommend placing the device on the base and ensuring the charge indicator shows at least 20%, although the optimal level would be higher 50%.
Resetting the Wi-Fi module settings on the robot
The most reliable way to force the robot to forget the old router and start searching for a new network is to perform a hard reset of the Wi-Fi module. On most models Xiaomi Vacuum, Roborock And Viomi This procedure is performed using a combination of buttons on the device's body. Typically, you need to simultaneously press and hold the power button and the return to base button (or the local cleaning button).
Hold the button combination for 3-5 seconds until you hear the voice prompt "Wi-Fi Configuration" or "Reset Wi-Fi." At this point, the wireless network indicator should start flashing orange, indicating that the device is in Wi-Fi mode. AP points (Access Point). The robot has now created its own network, which we will connect to.
☑️ Pre-reset check
In rare cases where the buttons on the case are unresponsive or damaged, you can try a software reset through the device's menu if the model has a screen or complex control system. However, for classic models Xiaomi Mi Robot Vacuum The mechanical combination of buttons remains the only standard method.
⚠️ Please note: Resetting the Wi-Fi connection does not delete saved room maps or cleaning history. This data is stored in the device's internal memory and is not affected by reconnecting to the network.
Setup via the Mi Home app
Once the robot has entered pairing mode, open the app Mi Home On your smartphone. If the device was previously linked to your account, it may appear in the list as "Offline" (gray icon). In this case, don't delete it immediately. Tap the device and try selecting "Settings" (three dots in the corner) → "Wi-Fi Settings" → "Change." The system will prompt you to enter a new password.
If automatic re-pairing doesn't work, remove the old device from the list (long-press the icon → Delete) and add it again. Tap the "+" in the upper right corner, and the app should automatically find the robot vacuum, making a distinctive searching sound. If the search fails, select the model manually from the "Robot Vacuums" catalog.
During setup, the app will request permission to access your local network and location—be sure to confirm these requests. Enter the password for your new Wi-Fi network. Important: the password must be entered correctly, including case-sensitive characters. Once entered, the data transfer will begin, which may take up to 2 minutes.
Problems with the 2.4 GHz and 5 GHz bands
One of the most common reasons for unsuccessful Wi-Fi upgrades is frequency incompatibility. Communication modules installed in robot vacuum cleaners Xiaomi, operate strictly at a frequency 2.4 GHzThey are physically unable to connect to networks. 5 GHzThe problem arises when a modern router combines both bands under one name (the Smart Connect or Band Steering function).
In this situation, the smartphone may automatically switch to the fast 5 GHz band, while the robot persistently searches for 2.4 GHz, which prevents the setup protocol from transmitting network parameters from the phone to the device. The solution is to access the router settings (usually at 192.168.0.1 or 192.168.1.1) and temporary separation of networks.
Give the 2.4 GHz network a unique name, such as Home_WiFi_2GConnect your smartphone to this network and repeat the robot setup process. After a successful connection, you can restore the band aggregation feature, although in some cases, robots perform more reliably when the 2.4 GHz band is permanently assigned to a separate SSID.

Regional settings and servers
Ecosystem Xiaomi is strictly tied to the region selected during account registration. If your robot vacuum cleaner is released for the Chinese market (the global version often also has Chinese servers by default), and your account in the app Mi Home If the device is registered to "Russia" or "Europe", it may not be possible to add it or change its Wi-Fi settings.
To check the device's region, look at the sticker on the bottom of the robot or on the box. If there are any hieroglyphs or text, Made for ChinaIn the app settings, the region must be set to "China." For European models (usually with an EU plug and multilingual instructions), the regions "Russia," "Germany," or "Singapore" are suitable.
How to change the region in Mi Home?
Go to your profile (the "Profile" tab in the bottom right) → Tap your current region (at the top) → Select the desired country from the list. The app will restart, and the list of devices will be updated.
When changing regions, old devices may disappear from the list because they are locked to the previous region's servers. In this case, you'll have to delete them and add them again in the correct regional profile. This is especially true when purchasing devices on marketplaces, where sellers often mix versions.
Diagnosing and troubleshooting connection errors
If, after all these steps, the Wi-Fi indicator continues to blink or stay red, and the app displays the "Unable to connect" error, you should run a thorough diagnostic. Often, the problem lies in the router's security settings. Some antivirus protections and features like AP Isolation (client isolation) blocks communication between the phone and the robot on the local network.
It's also worth checking MAC filtering. If the router has a "Whitelist" enabled, a new (or reset) robot won't be able to access the network, even with the correct password. Find the robot's MAC address (it's printed on a sticker on the bottom or announced when it's turned on) and add it to the router's exceptions.
As a last resort, you can perform a full reset of the device to factory settings. This usually requires pressing three buttons simultaneously or holding the power button for more than 10 seconds (depending on the model). This will delete maps and schedules, but often resolves software glitches in the network module.
⚠️ Caution: Do not update the robot's firmware when the Wi-Fi signal is unstable. Interrupting the download may brick the device, which will require repair by a service center.
Frequently Asked Questions (FAQ)
Is it possible to control the robot without the Internet, only via a local network?
Basic functions, such as starting a cleaning session or returning to base, can be operated over a local network if local control is configured. However, mapping, voice control, and remote activation from another network (via 4G) require a constant connection to the servers. Xiaomi Cloud.
The robot doesn't see my Wi-Fi network, even though other devices connect.
Most likely, your network name (SSID) contains characters that the robot module doesn't support (Cyrillic, special characters), or the SSID broadcast option is hidden. Try creating a guest network with a simple name in Latin characters to check.
What should I do if the app says "Device already added"?
This means that the robot is linked to another account. Mi HomeYou need to find the device in the account it's registered to, remove it from there, and only then add it to the new one. Without access to the old account, unlocking the device is difficult.
Do I need to reconfigure my room map after changing Wi-Fi?
No, the room map is stored in the robot vacuum's internal memory. After successfully connecting to a new network, all saved maps, virtual walls, and schedules should automatically sync with the cloud and appear in the app.
