How to reconnect the robot vacuum cleaner Xiaomi to Wi-Fi: instruction 2026

Xiaomi's robot vacuum cleaner stopped connecting to Wi-Fi after resetting, updating firmware or changing the router?The problem is familiar to many owners of Mi Robot Vacuum-Mop 2 Pro, S7, X10+ and others. Even if the device previously worked stable, reconnecting to the network often causes errors: the gadget "does not see" the network, requests a password endlessly or gives a message Connection failed.

This article provides step-by-step instructions for all scenarios, from standard Mi Home connectivity to manual network data entry to solving common bugs, and how to fix it without having to call the service, all of which have been tested on current firmware in 2026.

Why Xiaomi’s robot vacuum cleaner doesn’t connect to Wi-Fi again

Reconnection problems arise for several reasons, and it is important to differentiate them so as not to waste time on useless actions.

• 🔄 Resetting – after factory reset, the vacuum cleaner “forgets” all saved networks.
• 📶 Changing the router parameters – changing the network name (SSID), wifi.
• 🔄 Firmware Update – Some versions of the software reset network settings (relevant for Mi Robot Vacuum-Mop P and MOP) S6).
• 🛡️ Lockdown MAC-Addresses – the router can prevent the device from connecting via the filter MAC.
• 📡 Wi-Fi standards incompatibility – Xiaomi vacuum cleaners only work with 2.4 GHz, not 5 GHz.

The most common user error is trying to connect to the 5 GHz network. All Xiaomi robot vacuum cleaners (including the new models from 2023-2026) support only the 2.4 GHz range. If your router broadcasts both networks under the same name (SSID), the vacuum cleaner simply will not see it.

⚠️ Note: If you recently updated the router firmware, check if the mode is turned on 802.11r (Fast Roaming. It can block smart devices from connecting.

Preparation for reconnection: checklist

Before you start setting up, follow the mandatory steps:

Make sure that the robot vacuum cleaner is at least 20% charged.

Check that the router is broadcasting 2.4 GHz (disable 5 GHz if the names are the same)

Disable VPN and proxy on your smartphone

Update the Mi Home app to the latest version

Restart the router (turn off for 30 seconds)

-->

If you plug in a vacuum cleaner after resetting, wait until it completes initialization (Wi-Fi lights up or a voice message in Chinese/English). Xiaomi Mi Robot Vacuum-Mop 2 Lite and S5 models take up to 2 minutes to complete.

Also make sure your smartphone is connected to the same 2.4 GHz network you want to connect the vacuum cleaner to.Mi Home requires both devices to be on the same local network during the setup phase.

Method 1: Standard connection via Mi Home

This is a basic method that works 80% of the time, and the instructions are relevant for all models, including the Xiaomi Mi Robot Vacuum-Mop P and S6:

1. Open the Mi Home app and go to Devices → Add Device (+).
2. Select a Vacuum cleaner category and find your model. If it's not on the list, choose Another.
3. Press and hold the Wi-Fi button on the vacuum cleaner body (or Reset if the indicator doesn’t flash blue) until the beep.
4. The application will request to connect to the network. Select your SSID (network name) and enter the password.
5. Wait for the process to be completed (the indicator on the vacuum cleaner should burn blue, not blink).

If you fail to connect at the stage of entering a password, try:

• 🔄 Reboot router and vacuum cleaner.
• 📱 Delete the cache of the Mi Home application (in the smartphone settings).
• 🔒 Temporarily disable network protection (set open network without password) for the test.

💡

If the vacuum cleaner does not emit audible signals when holding the Wi-Fi button, check the battery level. At a discharge below 15%, the connection function is blocked.

Method 2: Manual network data entry (alternative method)

If the automatic connection doesn’t work, try manual mode.It’s suitable for Xiaomi Mi Robot Vacuum 1S, S5 and newer models:

1. Activate the connection mode on the vacuum cleaner (hold Wi-Fi until the indicator blinks).
2. In Mi Home, select Add Manual → Robot vacuum cleaner.
3. Enter your SSID and network password manually (registration is important!).
4. Bring your smartphone closer to the vacuum cleaner (at a distance of < 1 meter) and wait for synchronization.

If the Hidden SSID is hidden, the Mi Home may not display the list of available networks.

1. Go to the router settings and temporarily disable SSID hiding.
2. Put the vacuum cleaner on.
3. Return the router settings to the original state.

⚠️ Note: Some models (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Lite) do not support manually entering a password longer than 20 characters.

Method 3: Reset the vacuum cleaner settings before connecting

If previous methods didn't work, do a complete reset of the device, which will delete all the stored networks and return the factory settings:

1. Press and hold the Reset button (usually located under the lid or next to the power button) for 10-15 seconds until the double signal sounds.
2. The indicator should start flashing orange – this is a sign of a successful reset.
3. Connect the vacuum cleaner to the charging station and wait for initialization (blue indicator will light up).
4. Repeat the connection process via Mi Home (see Method 1).

Once reset, the vacuum cleaner may request a firmware update. Don't interrupt the process, which may lead to connection errors in the future. The Xiaomi S7 and X10+ models take up to 20 minutes to update.

Solving common connection errors

Let’s look at common mistakes and ways to eliminate them:

If the error persists, try connecting the vacuum cleaner to another network (such as a smartphone’s mobile hotspot) to help determine if the problem is in the router or in the device itself.

💡

Most connection errors are related to router settings, not a vacuum cleaner malfunction.Always start your diagnosis by checking the 2.4 GHz network and disabling additional features (such as WPA3 or 802.11r).

Features of connection for different models Xiaomi

Some models have unique connectivity nuances, and here are the key differences:

• 🤖 Xiaomi Mi Robot Vacuum-Mop 2 Pro: Requires a firmware update before first connecting. If the indicator flashes red, download the latest version of the software via Mi Home.
• 🤖 Xiaomi S7 / S7 MaxV: Supports connection to hidden networks, but may request re-entering of password after update.
• 🤖 Xiaomi X10+ / X10 Pro: Has a separate Reset button under the lid (not to be confused with the power button).
• 🤖 Xiaomi Mi Robot Vacuum 1S: Resetting requires re-association to your Mi Account.

For models with LEDARE (e.g., the S7 MaxV), the connection process may take longer due to additional sensor calibration.

For vacuum cleaners with a wet cleaning module (Mop series) make sure the water tank is empty before connecting - some firmware blocks Wi-Fi settings when cleaning is active.

What to do if nothing helps

If you’ve tried all of these methods but the vacuum cleaner still doesn’t connect to Wi-Fi, follow these steps:

1. Check router compatibility: Some router models (such as the ASUS RT-AX88U or the TP-Link Archer C5400) have aggressive security settings that block smart devices.
2. Update router firmware: Outdated versions of router software may conflict with the vacuum cleaner connection protocol.
3. Change region in Mi Home: Switch to Mainland China in the app settings, add a vacuum cleaner, then return the region back.
4. Contact Xiaomi for support: Give them the S/N (serial number) of the vacuum cleaner and screenshots of errors. For Xiaomi models, support responds within 24 hours.

If the vacuum cleaner is warranty, do not try to disassemble it yourself - this will void warranty obligations. Xiaomi service centers have special equipment for diagnosing the Wi-Fi module.

⚠️ Note: Do not buy used Xiaomi robot vacuum cleaners without a pre-test connection to Wi-Fi. Some devices imported from China may be tied to Chinese servers and not work in other regions.
