Reconnecting the robot vacuum cleaner Xiaomi to Wi-Fi: 3 working methods + solving errors

Why Xiaomi’s robot vacuum cleaner doesn’t connect to Wi-Fi and what to do about it

Have you moved the Xiaomi Mi Robot to another apartment, changed your router, or simply forgotten your password from the network — and the vacuum cleaner stubbornly refuses to connect to Wi-Fi? The problem is familiar to many owners of smart equipment. Unlike smartphones, where changing the network takes a couple of clicks, robot vacuum cleaners require a complete reset of network settings and re-assign to your Mi Home account.

In this article, we will discuss all the current ways to reconnect for Xiaomi Mi Robot Vacuum models (including 1S/1C/2/Pro), Viomi V2/V3, Dreame D9/F9 and others. And also find out why a vacuum cleaner can not see the network, freeze during the connection stage or give an error “I failed to connect” – and how to fix this without contacting the service.

⚠️ Important: If you sell or transfer a vacuum cleaner to another person, it's not enough to just dump Wi-Fi. You need to untie the device from your Mi Home account, otherwise the new owner will not be able to connect it.

Preparation: What to do before resetting Wi-Fi

Before you rush to reconnect the vacuum cleaner, check out 4 key points that affect the success of the procedure:

• 📶 The router operates in 2.4 GHz mode.Most of Xiaomi's robot vacuum cleaners (except the flagship models 2023)+ 5 GHz is not supported, if your router only broadcasts 5 GHz, turn on compatibility mode or split networks.
• 🔒 Wi-Fi passwords don't contain Cyrillic or special characters. Xiaomi vacuum cleaners don't take passwords with Russian letters, spaces or signs like this @#$%. Use Latin and numbers.
• 📱 The Mi Home app is updated.The outdated version may not see new models of vacuum cleaners or give out errors when connecting.Update the app on the App Store or Google Play.
• 🌍 The region in Mi Home is a vacuum cleaner model (CN-version), but the application selected region "Russia", the vacuum cleaner may not connect. Change region to China Mainland in the profile settings.

If at least one of the points is not met, the vacuum cleaner will not connect to Wi-Fi, even after repeated attempts, especially often users face a problem due to the wrong region, for example, trying to connect the Xiaomi Mi Robot Vacuum-Mop 2 Lite (sold only in China) through a Russian server.

Method 1: Quick reconnect without reset (if the vacuum cleaner is visible in the Mi Home)

If the robot vacuum cleaner is already tied to your Mi Home account and just lost connection to Wi-Fi (for example, after changing the router password), you can do without completely resetting. This method works for most models, except for the Dreame Bot W10 and Viomi V3 Pro — they have a different connection logic.

Instructions:

1. Open the Mi Home app and go to your vacuum cleaner page.
2. Slip on the three dots in the upper right corner → select Device Settings.
3. Scroll down and click Change Wi-Fi (or Change Network in newer versions of the app).
4. Follow the instructions on the screen: the app will suggest manually entering a password from the new network or scanning. QR-router.

⚠️ Warning: If the vacuum cleaner never plugs in, check if the antivirus or firewall on your phone is blocking access to the local network. Try temporarily disabling them or using another smartphone.

Method 2: Complete Wi-Fi reset (if the vacuum cleaner is not visible in the Mi Home)

If the previous method did not work or the vacuum cleaner is not displayed in the application, you will need to hardware reset network settings.

For Xiaomi Mi Robot (all versions), Viomi V2/SE

Press and hold the Wi-Fi (or Reset) button on the vacuum cleaner for 5-10 seconds until you hear an audible beep (voice message in Chinese or English: "Wi-Fi reset").

Press the power button and the home button for 5 seconds at the same time, the vacuum cleaner will emit a long signal and reset, and when turned on, the Wi-Fi indicator will flash blue.

On these models, the reset is performed through the touch panel:

1. Press and hold the menu button (three bars) for 3 seconds.
2. In the menu that opens, select Settings → Reset Wi-Fi.
3. Confirm the action by pressing OK.

After the vacuum cleaner is discharged, it will automatically go into tether mode (the indicator flashes orange/blue) and can now be connected to the new network via Mi Home, as in the first run.

Method 3: Complete factory reset (if the vacuum cleaner is sold or not connected)

If you transfer the vacuum cleaner to another owner or all previous methods have failed, you will need a complete reset (including untidying your Mi Home account) that will delete all settings, room maps and cleaning history.

⚠️ Warning: Once fully reset, the vacuum cleaner will not be found through the old Mi Home account, and all stored maps and cleaning schedules will be deleted without recovery.

Instructions for most models:

1. Turn on the vacuum cleaner and wait for loading.
2. Press and hold the power button and the Spot Cleaning button simultaneously for 10-15 seconds.
3. The vacuum cleaner will emit a long beep and reboot, and after switching on, all the indicators will flash, and the voice assistant will report the reset (in English: "Factory reset complete").

For touchscreen models (Xiaomi Mi Robot Vacuum-Mop 2 Pro, Dreame Bot W10):

1. Go to Settings → Additional → Reset to factory.
2. Enter. PIN-code (by default 1234 or 0000 if you have not changed it).
3. Confirm the reset.

Once completely reset, the vacuum cleaner will be like new, and now it can be linked to another Mi Home account and connected to Wi-Fi from scratch.

A full reset is a last resort. If the vacuum cleaner just doesn't connect to Wi-Fi, try resetting only network settings first.
