Xiaomi vacuum cleaners are no longer a luxury — they are now indispensable cleaning assistants that save time and effort. But without a Wi-Fi connection, you lose half of the functionality: remote control via Mi Home, voice assistant, automatic schedules and even some cleaning modes. Network connectivity problems are one of the most common complaints users have, especially after resetting or buying a used device.
In this article, we will discuss all possible ways to connect Xiaomi Mi Robot vacuum cleaners (including S5, S6, S7, Pro, Ultra and others) to Wi-Fi, explain why the device may not see the network or refuse to connect, and give unique tips for eliminating errors that are not in the official documentation. If you have already tried to connect and received an error like “failed to connect to the network” or “check password” – here you will find a solution.
1.Preparation for connection: what to check before starting
Before you start setting up, make sure that all the conditions are met, which will eliminate 80% of the typical problems:
- 📶 Wi-Fi router is stable, vacuum cleaner will not connect to the network with frequent breaks or weak signal, check that other devices (smartphone, laptop) are connected and do not lose connection.
- 🔋 The vacuum cleaner is at least 30 percent charged. When the charge is low, some models block the network setting. Connect the device to the dock for 10 to 15 minutes.
- 📱 The latest Mi Home app is installed, download it from Google Play or the App Store. Older versions may not support newer models of vacuum cleaners.
Also check that your router supports the Wi-Fi standard. 2.4 Xiaomi vacuum cleaners (except for some flagship models) 2023–2026 year) not working with networks 5 If you have a dual-band router, make sure the networks are separated (they have different names, for example, MyWiFi_2.4 and MyWiFi_5).
⚠️ Warning: If you use a mesh system (such as TP-Link Deco or Keenetic), temporarily disconnect it and connect the vacuum cleaner to the main router.
2. Step-by-step instruction: connection via the Mi Home app
This is the basic and most reliable way. Follow the instructions carefully, because even one step can lead to an error.
- Start Mi Home and log in (or sign up if you don’t have an account).
If in step 6, the app requests a confirmation code (the numbers on the vacuum cleaner case), enter it, usually located on a sticker under the lid or on the bottom of the device.

3. Alternative ways to connect (if Mi Home does not work)
Sometimes the standard method fails due to application errors or vacuum cleaner firmware features, and in such cases, try one of the alternatives:
Method 1: Connecting with Mi Home Lite
If the main application is making errors, install the lightweight version of Mi Home Lite (available for Android). The connection algorithm is similar, but the interface is simpler and some bugs of the main application are absent.
Method 2: Manual addition through IP-address
This is a method that's suitable for advanced users, and you'll need to:
- In Mi Home, select "Add Manually» → introduce IP-address MAC-vacuum cleaner address (indicated on the sticker).
Method 3: Resetting vacuum cleaner settings
If the vacuum cleaner was previously connected to another network and does not want to reconnect:
- Press and hold the Reset button (usually located under the lid or next to the power button) for 10 seconds until the indicator lights up.
- The vacuum cleaner will sound and restart, and then repeat the standard connection procedure.
⚠️ Warning: Resetting will remove all stored room maps and individual cleaning settings. If the vacuum cleaner previously worked with another Mi Home account, it will have to be re-tied.
4. Common mistakes and their solutions
Even if you follow the instructions correctly, you can get errors, and we've collected the most common problems and ways to fix them:
| Mistake. | Reason. | Decision |
|---|---|---|
| “I couldn’t get on the network.” | Incorrect Wi-Fi password or router blocks the device | Check the password. Turn off the filter. MAC-Addresses in router settings. |
| The vacuum cleaner does not emit an audible signal when added | Device discharged or not on | Charge the vacuum cleaner for 30+ minutes. Press the power button until the beep. |
| The device is not supported in your area. | The region in Mi Home does not coincide with the vacuum cleaner region | Change the region in your Mi Home account settings (you may need to create a new account). |
| The vacuum cleaner plugs in, but shuts down immediately. | Weak Wi-Fi signal or conflict IP-address | Move the vacuum cleaner closer to the router. In the router settings, turn on DHCP or pin the IP behind the vacuum cleaner. |
| "The confirmation code is wrong." | Misprint when entering code from the body | Check the code on the sticker (sometimes the letters "O" and "0" or "I" and "1" are confused). |
If the error persists, try connecting the vacuum cleaner to another network (such as a smartphone’s mobile hotspot). If that doesn’t work, the problem may be the device’s firmware (more on this in the next section).

5. firmware problems: when to update the software
Outdated or “curved” firmware is a common cause of Wi-Fi connection problems, especially for vacuum cleaners purchased on AliExpress or used: the previous owner could install unofficial software.
Check the firmware version:
- Open Mi Home → Select a vacuum cleaner → Settings → About the device.
- Compare the version with the latest official version on Xiaomi’s website (for example, for the first time). S6 current version 2026 year-end — 3.5.9_0046).
If the version is outdated:
- 🔄 Update via Mi Home: Go to Settings → Firmware update.
- 💻 Update manually: download the firmware from the official website and download it through Mi Home (Update section» → «Select a file»).
⚠️ Note: Do not install firmware from third-party developers (for example, from forums) 4PDA). This can lead to loss of warranty and unstable operation of the device. Use only official files from Xiaomi.

6. Optimizing Wi-Fi for stable vacuum cleaner operation
Even if the connection is successful, the vacuum cleaner may lose communication during cleaning. To avoid this, set up the router according to these recommendations:
- 📡 Turn off Band Steering in the router settings. It automatically switches devices between 2.4 GHz and 5 GHz, which can knock down the vacuum cleaner.
- 🔒 Use encryption. WPA2-PSK. Xiaomi vacuum cleaners do not support new standards like WPA3 or WPA2/WPA3 Mixed.
- 📶 Set the static. IP-vacuum address DHCP This will prevent address conflicts.
- 🔄 Turn off the power savings for Wi-Fi (if you have one). Some routers shut down the network at low load, which breaks the connection.
If you have a large home and your Wi-Fi signal is weak in some rooms, consider:
- 📶 Install the repeater (signal repeater) in the area of weak coverage.
- 🔌 Use Powerline adapters (internet transmission via wiring).
- 🌐 Set up a guest network on the router specifically for the vacuum cleaner (with a separate one) SSID password).
💡
If the vacuum cleaner is constantly losing communication during cleaning, try to reduce the Wi-Fi transmission power in the router settings. Sometimes too strong a signal leads to interference.
7. Connecting a vacuum cleaner to a smart home (Google Home, Alice, HomeKit)
Once connected to Wi-Fi, the vacuum cleaner can be integrated into the smart home ecosystem, and here's how to do it for popular platforms:
Google Assistant / Google Home
- Open Mi Home → Select a vacuum cleaner → Settings → Add to Google Assistant.
- Follow the instructions on the screen for bundling accounts.
- Say in your voice, “OK Google, turn on the vacuum cleaner.”
Yandex Alice
- In the Yandex app, go to Devices → Add Device → Xiaomi.
- Sign in through your Mi Home account.
- Select a vacuum cleaner from the list of available devices.
Apple HomeKit
Officially, Xiaomi vacuum cleaners do not support HomeKit, but you can use workarounds:
- 🔌 Home Assistant (requires customization skills).
- 📱 Through the app HOOBS (paid, but easier to set up).
⚠️ Note: When integrated with Yandex Alice, some vacuum cleaner features (such as zoning or suction power tuning) may not be available.Use Mi Home for fine-tuning.
💡
To work with voice assistants, make sure that the vacuum cleaner and smartphone are connected to the same Wi-Fi network. Otherwise, commands may not be executed.
