How to reconnect a Xiaomi vacuum cleaner to Wi-Fi: Complete instructions for a new router

Changing your home router or changing your Wi-Fi network settings often results in smart devices Xiaomi — including robot vacuum cleaners — lose connection. Unlike smartphones or laptops, where entering a new password is enough, vacuum cleaners require full reconnection procedure through the proprietary app. However, many users encounter errors such as Failed to connect, endless network search or sudden device disconnection after successful connection.

The problem is complicated by the fact that the application interface Mi Home (or Xiaomi Home in new versions) is updated regularly, and connection algorithms may differ depending on vacuum cleaner models (Mi Robot Vacuum-Mop 2 Pro, S7 MaxV Ultra etc.) and firmware region. For example, devices with Chinese firmware (CN) sometimes refuse to work with European routers due to frequency restrictions 5 GHzIn this article we will discuss all current methods of reconnection, including bypassing typical errors and optimizing the Wi-Fi network for stable operation of the vacuum cleaner.

If you've already tried connecting but your vacuum still doesn't appear in the app, don't rush to reset it to factory settings. In 80% of cases, the problem can be resolved by adjusting your router settings or choosing an alternative connection method. And for owners of older models (e.g., Mi Robot Vacuum 1S) we have prepared separate recommendations taking into account their specific features.

1. Preparation: what you need to do before connecting

Before you begin setting up, make sure that your new router meets the minimum requirements for operation with a vacuum cleaner XiaomiMost problems arise due to incompatibility of Wi-Fi standards or incorrect security settings.

First, check frequency range:

• 📶 2.4 GHz — mandatory for all vacuum cleaner models Xiaomi. Even if your router supports 5 GHz, the device will not be able to connect to it.
• 🔄 Opening hours: the router must support the standards 802.11 b/g/n. Modern models (for example, Mi Robot S7) work with 802.11ac, but for stability it is better to choose mixed mode b/g/n.
• 🔒 Encryption type: only WPA2-PSK (AES). WPA3 or TKIP are not supported.

Secondly, pay attention to DHCP settings:

⚠️ Attention: If DHCP is disabled on your network or static IP mapping is used, the vacuum cleaner will not be able to obtain an address automatically. Enable DHCP or manually reserve an IP address for the vacuum cleaner's MAC address (you can find it in the app). Mi Home in the section Device → Settings → About device).

It is also worth temporarily disabling the following router functions (if they are active):

• 🛡️ MAC address filtering (may block new device).
• 🔄 Guest network (the vacuum cleaner will not be able to connect to an isolated network).
• 📡 Smart Wi-Fi or Band Steering mode (can force devices to switch to 5 GHz).

2. Method 1: Standard connection via the Mi Home app

This is the basic method that works for most models (Mi Robot Vacuum-Mop 2 Pro, S7, E10 etc.). The instructions are valid for the latest versions of the application (2026–2026).

Step 1. Make sure the vacuum cleaner is turned on and close to the router (no further than 1-2 meters). Press and hold the power button on the device. 3-5 secondsuntil you hear a beep (on some models a white indicator will light up).

Step 2. Open the app Mi Home (or Xiaomi Home for new devices) and follow these steps:

1. Click + → Add device.
2. Select a category Vacuum cleaners (or enter the model manually in the search bar).
3. Follow the on-screen instructions: the app will prompt you to connect to the vacuum cleaner's temporary network (the name will look like this) mirobot-XXXX).
4. Once connected, return to the app and select your primary Wi-Fi network. 2.4 GHz, enter the password.

If the process is stuck at the stage Connecting to the network:

• 🔄 Restart the vacuum cleaner (hold the power button 10 seconds).
• 📱 Reinstall the app Mi Home (sometimes the cache interferes with the connection).
• 🌐 Check that your phone is connected to the same network 2.4 GHz, as well as a vacuum cleaner.

3. Method 2: Connecting via AP mode (for older models)

If the standard method did not work, and you have a model Mi Robot Vacuum 1/1S or another old version, try access point mode (AP Mode)This method bypasses router compatibility issues, but requires additional steps.

Algorithm of actions:

1. Hold the buttons Food + Home on a vacuum cleaner 5 secondsuntil you hear a voice message "AP Mode" (or the orange indicator will light up).
2. On your phone, connect to the vacuum cleaner's network (mirobot-XXXX).
3. Open your browser and enter the address 192.168.8.1.
4. In the web interface, select your Wi-Fi network 2.4 GHz and enter the password.

⚠️ Attention: After successfully connecting in AP mode, the vacuum cleaner may "forget" the old network settings. If you need to restore the previous configuration, you'll have to repeat the procedure for the old router.

If the web interface does not open:

• 🔌 Check that the vacuum cleaner is charged (at least 20%).
• 📱 Try a different browser (for example, Chrome or Firefox).
• 🔄 Restart your vacuum cleaner and try logging in again AP Mode.

4. Solving typical connection errors

Even with the correct router settings, your vacuum cleaner may still display errors. Let's look at the most common ones and how to fix them.

A critical feature for owners of routers with firmware OpenWRT or DD-WRTXiaomi vacuum cleaners may not connect due to a disabled setting WMM (Wi-Fi Multimedia). Enable it in your wireless network settings (Wireless → Advanced Settings → WMM Mode: Enabled).

If the error persists, try alternative connection method via the app Mi Home on another phone (for example, on Android, if originally used iPhone). Sometimes platform bugs prevent the system from working correctly.

5. Optimizing the Wi-Fi network for stable operation of the vacuum cleaner

Even after successful connection, the vacuum cleaner may lose connection during cleaning. This is due to moving around the apartment, interference from other devices, or router settings. To avoid connection drops:

1. Select the optimal Wi-Fi channel:

• 📊 Use apps like Wi-Fi Analyzer (Android) or NetSpot (iOS/macOS) to find the least crowded channel in range 2.4 GHz.
• 🔢 Recommended channels: 1, 6, 11 (do not intersect with neighboring networks).

2. Adjust the signal strength:

• 📶 If the router supports transmission power adjustment (Tx Power), set the value 75–100% for better coverage.
• 🏠 For larger apartments, consider installation Wi-Fi repeater or Mesh systems (For example, Xiaomi Mi Wi-Fi Repeater 2).

3. Disable the router's smart features:

• 🔄 Band Steering (forced switching to 5 GHz).
• 🛡️ Intrusion Detection or Firewall (may block vacuum cleaner bags).
• ⚡ Fast Roaming (802.11r) (not supported by most vacuum cleaners).

⚠️ Attention: If you use dual-band router with a shared SSID (For example, Keenetic or ASUS RT-AX88U), the vacuum cleaner may accidentally connect to 5 GHz, which will lead to loss of connection. Divide the networks into MyWiFi_2G And MyWiFi_5G manually.

6. Resetting the vacuum cleaner to factory settings

If all methods have been tried, but the vacuum cleaner still does not connect to the new router, the only option left is full resetThis procedure will delete all saved networks, room maps, and cleaning settings, so use it only as a last resort.

How to reset:

1. Turn off the vacuum cleaner.
2. Press and hold the button Nutrition and hold 10-15 secondsuntil you hear a beep (on some models the indicator will light up red indicator).
3. Release the button and wait for the vacuum cleaner to reboot (it will make a voice message in Chinese or English).

After resetting, repeat the connection procedure through the application Mi Home (cm. Method 1If the vacuum cleaner was previously linked to a different Xiaomi account, confirmation of the original owner will be required (a notification will be sent to the app).

⚠️ Attention: On models Mi Robot Vacuum-Mop 2 Pro and newer factory reset also removes sensor calibrationAfter connecting, run a test cleaning to allow the vacuum cleaner to reconfigure its navigation system.

7. Alternative connection methods

If standard methods don't work, try these options:

1. Connection via Mi Home on another device:

• 📱 Use a second phone (preferably on Android, if you initially tried on iPhone).
• 🌍 Change your region in your account settings Mi Home (for example, on Singapore or Germany).
