Changing your home wireless network password or installing a new router often causes your smart devices to suddenly stop working. Xiaomi robot vacuum cleanerA device that just yesterday obediently cleaned the apartment according to schedule may today simply stand at the base, blinking its indicator, waiting for a connection. The problem is that the device stores old credentials in its memory and cannot automatically update them when the network infrastructure changes.
Unlike smartphones, which automatically request a new password when attempting to connect to the internet, IoT gadgets require manual intervention. You'll have to forcibly disconnect the old device from the network and re-pair it. This is standard for the ecosystem. Mi Home, and it can be solved fairly quickly if you know the correct sequence of actions.
In this guide, we'll cover all the ins and outs of resetting your Wi-Fi module. We'll cover methods for resetting the Wi-Fi module on various models, from classic Roborock to the latest models Viomi And DreameWe'll also cover common errors related to the 2.4 GHz signal frequency and the app's performance in different regions.
Preparing to reconfigure the network
Before you begin manipulating the buttons on the vacuum cleaner, you need to make sure your network is ready to receive the device. The wireless signal frequency is critical. Most robot vacuum cleaner models, including popular series Xiaomi Vacuum Mop And Roborock S5/S6, operate exclusively in the range 2.4 GHz.
If your new router combines 2.4 GHz and 5 GHz networks under a single name (Smart Connect), the device may attempt to connect to a higher frequency band where it physically cannot operate. In this case, the setup process will freeze while searching for a device or return a connection error. We recommend temporarily separating the networks in the router settings or creating a guest network strictly for 2.4 GHz.
⚠️ Attention: Make sure that GPS (geolocation) is enabled on the smartphone from which you will be setting up the app. Mi Home requires access to geolocation to scan Wi-Fi networks, otherwise it simply won't see your router in the list of available ones.
It's also worth checking the app version. If you haven't updated it in a while, Mi Home, it may contain bugs that prevent older devices from initializing correctly. Go to the app store and make sure you have the latest available version. Also, make sure Bluetooth is enabled on your phone—this will speed up the process of finding the device in pairing mode.
Resetting Wi-Fi settings on different models
The procedure for switching a vacuum cleaner into pairing mode varies depending on the manufacturer and model. The Xiaomi ecosystem includes numerous OEMs, such as Roborock, Viomi, Dreame And 360, so there's no universal button. Below are instructions for the most common series.
For classic models such as Xiaomi Robot Vacuum (first generation) and Mijia 1CTo do this, you need to simultaneously press and hold two buttons on the top panel: the power button and the return to base button. Continue holding them for 5-7 seconds until you hear a voice message about rebooting the Wi-Fi or until the network indicator starts flashing rapidly.
Devices of the series Roborock (S5, S6, S7) often have a separate Wi-Fi reset button or require pressing the "Home" and "Power" buttons together. On some models Dreame And Viomi You need to press and hold the power and charge buttons simultaneously. If the case has a separate hole labeled "Reset," use a paperclip to briefly press it.
☑️ The vacuum cleaner is ready for setup
After successfully entering setup mode, the wireless network indicator should begin blinking rapidly. This indicates that the device's Wi-Fi module has activated the access point or is in standby mode. If there is no blinking, repeat the procedure, holding the buttons slightly longer, but no more than 15 seconds, to avoid a full factory reset, which will delete the room maps.
Step-by-step instructions for connecting via Mi Home
Once the device is in standby mode, open the app Mi HomeIf you previously removed the vacuum cleaner from the device list (which is sometimes required for a clean re-pairing), tap the plus sign in the upper right corner to add a new device. If the device remains in the list but shows as "Offline," try tapping it—the system will often prompt you to reconfigure the Wi-Fi connection.
In device addition mode, the app will begin scanning. Make sure you're near the vacuum. Once the system detects the device, a pop-up window will appear prompting you to add it. Click "Next." Next, select your wireless network from the list and enter a new password. Be careful: the password is case-sensitive, and spaces are not allowed.
Menu path: Mi Home → "+" (Add) → Automatic detection → Select Wi-Fi network → Enter passwordThe data transfer process may take from 30 seconds to 2 minutes. During this time, a progress bar will be displayed on the phone screen. Do not exit the app or lock the smartphone screen. During the configuration transfer, the phone and vacuum cleaner must be in close proximity to ensure stable data exchange.
If setup is successful, the indicator light on the vacuum cleaner will stop flashing and turn solid (or turn off, depending on the model), and the voice assistant will confirm the connection. The device's status in the app will change to "Online." You can now test the vacuum cleaner's operation by starting a cleaning session remotely.
Using AP mode for complex cases
Standard connection mode (EZ Mode) sometimes fails due to router or smartphone driver issues. In this case, AP (Access Point) mode comes to the rescue. In this mode, the vacuum cleaner automatically creates a temporary Wi-Fi network, which you need to connect to with your phone to transfer settings. This is a more reliable, albeit slightly slower, method.
To activate AP mode, you typically need to hold down the Wi-Fi reset buttons for a longer period (about 10-15 seconds) until you hear a specific beep, or select this mode in the app menu when adding a device (the "Wi-Fi not connecting?" icon). Once activated, the vacuum cleaner will create a network with a name like "robottmp_xxxx" or "mi_vacuum_xxxx".
⚠️ Please note: When switching to the vacuum's Wi-Fi network, your phone will temporarily lose internet access. This is normal. Do not attempt to manually restore mobile data until the app has completed setup.
After connecting your phone to the vacuum cleaner's network, return to the application Mi HomeIt will automatically detect that you're on the device's network and continue the setup process. You'll again need to select your primary home network and enter the password. The vacuum cleaner will receive data, attempt to connect to the router, and the phone will automatically reconnect to your primary network.
| Parameter | EZ Mode (Standard) | AP (Access Point) mode |
|---|---|---|
| Speed of setup | Fast (30-60 sec) | Slower (2-3 min) |
| Stability | Average (depending on the router) | High (direct connection) |
| User actions | Minimum | Manual Wi-Fi switching is required |
| When to use | On the first try | If standard mode doesn't work |
Using AP mode is especially important for routers with client isolation enabled or complex WPA3 security settings that may block the standard discovery protocol. If you're using a mesh system, AP mode is also often a more reliable initial association method.
Regional settings and servers
One of the most common causes of connection issues is a mismatch between the app's region and the device's region. Vacuum cleaners purchased globally (Global Version) are usually locked to the "Europe" or "Singapore" server. Devices ordered from China (CN Version) require the "China" region to be selected in the Mi Account profile settings.
If you changed the region in the app, old devices may disappear from the list or stop responding. To reconnect the Chinese version of the vacuum after changing the router, you may have to temporarily switch the app region to China, add the device, and then (this doesn't always work) try changing the region back. However, most often, the device is tightly bound to the initial activation server.
How to find out the region of a device?
Look at the box or instructions. If there are Chinese characters and a plug without a grounding terminal (or with an adapter), it's a CN version. If the box has languages and a European plug, it's a Global version. The region is also indicated on the sticker at the bottom: the model ending in "CN" or "GL."
It is important to understand that switching regions in the application Mi Home Hides devices linked to a different server. If you have appliances in your home from different regions, managing them from a single profile won't be easy. In this case, to reconnect the vacuum cleaner, you'll have to temporarily change the region in your profile to the one the device is linked to.
Diagnosis and solution of typical errors
Even if all instructions are followed, errors may occur. Code 1001 or the message "Unable to connect" often indicate an incorrect password or a weak signal. Check that you're not using special characters in your Wi-Fi password, which may be incorrectly processed by your vacuum's firmware. Temporarily simplify the password to letters and numbers to test.
An error at the 99% stage usually means that the vacuum cleaner has received the settings and successfully connected to the router, but is unable to access Xiaomi's servers for authorization. This could be due to the servers being blocked by your ISP or DNS. Try setting Google's DNS servers in your router settings (8.8.8.8) or Cloudflare (1.1.1.1).
- 📶 Weak signal: The vacuum cleaner may not connect if the signal strength at the base station is below -80 dBm. Use a Wi-Fi analyzer.
- 🔒 Port blocking: Make sure that the "Guest Network" mode with client isolation for the main network is not enabled in the router.
- 📱 Application cache: Clear the Mi Home app cache in Android settings or reinstall the app.
It's also worth checking if MAC address filtering is enabled on your router. If this feature is enabled, a new (or factory-reset) vacuum cleaner will be blocked even if the password is entered correctly. Find the MAC address on the sticker on the bottom of the device and add it to the router's whitelist.
Why doesn't the vacuum cleaner see the 5 GHz network?
The Wi-Fi modules in most budget and mid-range Xiaomi robot vacuums are hardware-limited to the 2.4 GHz band. They are physically unable to receive a 5 GHz signal. Even if your router broadcasts networks with the same name, the vacuum may get stuck trying to handshake with an unsupported protocol. The solution is to separate network names (SSIDs) in the router.
Is it possible to connect a vacuum cleaner without the Internet?
Local control of the vacuum cleaner via Wi-Fi without internet access is not possible, as the command is sent through the Xiaomi cloud server. However, if you had already configured scenes or schedules before the internet outage, they can operate autonomously if the router is distributing IP addresses (DHCP), but remote control and maps will not be updated.
What should I do if the card disappears after reconnecting?
When you reset your Wi-Fi, the map is usually saved in memory. If it's gone, try going to the map settings in the app and selecting "Restore." If that doesn't work, you may have reset your device to factory settings. In this case, you'll need to rebuild the map and run a full cleaning.
Does changing a router affect the warranty?
No, manually reconfiguring the device to a new router or changing the password is a standard operating procedure and does not affect the manufacturer's warranty. The warranty is voided only if the device is physically opened or damaged by moisture.
