Moving cleaning equipment to a new home or simply changing internet service providers often requires users to reconfigure their smart device. Xiaomi and their sub-brands such as Roborock or Viomi, store data about the network they were initially connected to. This means that if you change your router, your device won't be able to automatically switch to the new access point without your intervention.
Change Wi-Fi network to robot vacuum cleaner The process isn't complicated, but it does require following a specific sequence of steps. Errors during the pairing process often result in the device blinking its indicators for a long time but never appearing in the app's list of available devices. Understanding the communication module's logic will help avoid wasted time and frustration.
In this guide, we'll cover all the current reconnection methods, from the standard reset procedure to solving specific signal frequency issues. You'll learn why Mi Home app The vacuum cleaner may not be visible, and how to properly prepare your smartphone for successful synchronization with the new router.
Preparing to reconfigure your network connection
Before tweaking the settings, make sure the basic components of your smart home system are working properly. Make sure the new router is turned on and sending a signal, and your smartphone is within range. The robot should be placed on its base and fully charged, as the module will be damaged during the reconnection process. Wi-Fi consumes a significant amount of energy.
The frequency of the wireless network is critical. Most vacuum cleaner models Xiaomi They only support the 2.4 GHz band and don't see 5 GHz networks. If your router broadcasts both networks under the same name, try temporarily separating them in the router settings or force your phone to switch to 2.4 GHz before starting setup.
⚠️ Attention: Make sure AP Isolation is disabled on your router. If it's enabled, devices on the same network won't be able to communicate, and the app won't be able to pass new connection settings to the vacuum.
It is also worth checking the version of the smartphone's operating system and the availability of updates for the application itself. Mi Home or RoborockOlder versions of the software may contain bugs that prevent new devices from being detected or passwords from being transmitted correctly. A stable internet connection on your phone is also required for authorization in the cloud service.
How to completely reset the Wi-Fi module on a vacuum cleaner
The most reliable way to force the device to forget the old network and start searching for a new one is to perform a full reset of the wireless module. This is available on most models. Xiaomi A special button combination is provided. Most often, you need to simultaneously press and hold the power button and the return to base button (or the spot cleaning button) for 5-10 seconds.
A successful reset will be indicated by a voice prompt in English or Chinese, along with a change in the Wi-Fi indicator blinking pattern. Typically, the light will begin rapidly blinking blue, signaling the switch to the reset mode. conjugationsIn this state, the vacuum cleaner creates its own access point or becomes visible for searching via Bluetooth.
☑️ Checklist before reset
If voice guidance is disabled, rely solely on visual cues. Some models may require holding the buttons for longer—up to 15 seconds. After resetting, the device may reboot, which is normal for updating network configuration settings.
What to do if the buttons don't work?
If a physical reset doesn't help, try disconnecting the robot from the base, turning it over, and finding the emergency reset button near the battery cover. Press it with a paperclip and hold for 5 seconds.
Step-by-step instructions for connecting via Mi Home
Once the vacuum cleaner is in pairing mode, open the app Mi Home On your smartphone. Tap the plus sign in the upper right corner to add a new device. The system may automatically suggest a detected device at the top of the screen. If this doesn't happen, select the "Vacuum Cleaners" category and find your model in the list or search by name.
Next, the app will ask you to select a region. Make sure you select the country that matches your account, as device linking is often region-specific. You'll then need to select a Wi-Fi network from the list of available ones. The password is entered manually, so be careful with the case and other characters.
The data transfer process can take from 30 seconds to 2 minutes. During this time, the phone generates a configuration package and transmits it to the vacuum cleaner. A progress bar will be displayed on the screen. Do not switch to other apps or lock the smartphone screen during this time to avoid interrupting the data transfer.
| Indicator status | Meaning of the state | User action |
|---|---|---|
| Orange (constant) | Waiting for connection | Run a search in the app |
| Blue (flashing) | Pairing mode | Confirm adding in the app |
| Blue (constant) | Successful connection | No problem, the device is ready. |
| Red (flashing) | Network error | Repeat password reset and verification |
Troubleshooting device visibility issues
A common situation is when the vacuum cleaner is reset, but the app doesn't detect it. First, check the app's permissions. Mi HomeTo function properly, it requires access to geolocation (even if you're not moving; this is necessary for scanning Wi-Fi networks), local network access, and Bluetooth. Without these permissions, searching for devices will be unsuccessful.
Another common cause is the use of complex Wi-Fi passwords. If the password contains spaces or specific characters, some modules Xiaomi They may not process them correctly. Try temporarily simplifying your router password by adding numbers and Latin letters, and then try the connection procedure again.
⚠️ Attention: Make sure your router isn't using a hidden SSID (network name). Xiaomi vacuum cleaners can't connect to networks whose names are hidden from broadcast. Make the network visible during setup.
It's also worth considering the number of connected devices. If the network already has the maximum number of clients (usually 10-15 for budget routers), the new device may not receive an IP address. In this case, temporarily disconnect other devices or expand the address pool in the settings. DHCP servers.
Setup via Bluetooth Low Energy
Modern models of robotic vacuum cleaners, such as Xiaomi Vacuum-Mop 2 or Roborock S7, support fast connection technology via BluetoothThis method significantly simplifies the process, as it eliminates the need to manually enter a password—Wi-Fi network information is automatically copied from the phone's settings.
To use this method, make sure Bluetooth is enabled on your smartphone. When adding a device, the app will automatically detect the vacuum via Bluetooth and offer "Quick Connect." You'll only need to confirm the action. This is especially convenient if you've changed your router and don't remember the exact password for the new network.
However, if automatic transfer fails, you can always switch to manual mode. In the device addition interface, select "Connect manually" or "Enter password." This will switch the data transfer protocol from Bluetooth to standard Wi-Fi Direct, which is more reliable, albeit a bit slower.
Common mistakes and how to fix them
Even if you follow all the instructions, specific errors may still occur. The "Vacuum is busy" error code usually means the device is already linked to another account. In this case, you need to go to the device settings on the old account and select "Unlink device" or "Delete," then perform a hard reset using the buttons.
The "Unable to connect to the network" error is often rooted in the router's security settings. Vacuum cleaners Xiaomi may not support the latest encryption standards WPA3If your router is configured for "WPA3 Only" mode, switch it to "WPA2/WPA3 Mixed" mode or temporarily set it to "WPA2 Only".
Sometimes, assigning a static IP address helps. Go to your router settings, find the DHCP Client List, select the vacuum cleaner by MAC address, and assign it a static IP address. Then try adding the device to the app again. This eliminates address conflicts that could interrupt the handshake process.
Why does the app say "Device already added"?
This message appears if you're trying to add a vacuum cleaner that's already linked to your account but is displayed in a different region or under a different name. Check the list of devices by room. If the device is found, simply rename it or change the room in the settings without adding it again.
Is it possible to change the region in the app without losing data?
Changing the region in the Mi Home app settings will remove all devices from the current list. Map data and cleaning history are stored on the servers of the selected region. To switch a vacuum cleaner to a different region, remove it from the old account (reset it) and add it again, selecting the desired region at startup.
What should I do if the robot doesn't see the 2.4 GHz network?
Make sure your Wi-Fi channels aren't overloaded. Vacuum cleaners work best on channels 1, 6, or 11. You can force one of these channels in your router settings instead of "Auto." Also, check if "Guest Network" mode is enabled, as it often isolates devices from each other.
