How to turn on Bluetooth on the robot vacuum cleaner Xiaomi: all ways + error solving

Why Bluetooth is important for Xiaomi’s robot vacuum cleaner – and when to turn it on

Xiaomi’s robot vacuum cleaners (including the Mi Robot Vacuum, Viomi, Dreame) use Bluetooth not only to connect to a smartphone, but also to accurately navigate, sync with other smart home devices, and even update firmware. However, many users face the problem that the Bluetooth module can be turned off by default to save battery power or due to a software failure.

You will need to turn it on in three cases:

• 📱 First connection to Mi Home or Xiaomi Home (without Bluetooth synchronization with Wi-Fi is impossible).
• 🔄 Resetting vacuum cleaner settings - after it, the module often turns off automatically.
• 🛠️ Diagnostics of navigation or connection problems (for example, if a vacuum cleaner does not build a room map).

This article provides 4 proven ways to enable Bluetooth on Xiaomi robots (including models without a button on the body), as well as unique solutions for errors such as “Device not found” or “Bluetooth unavailable”, which are not described in the official documentation.

Method 1: Activate Bluetooth via a button on the body (for models with a physical key)

The simplest method is to use a physical button on the vacuum cleaner body, which works for most Mi Robot Vacuum models (e.g. Mi Robot Vacuum-Mop 2 Lite, Mi Robot Vacuum-Mop P) and all Viomi devices.

Instructions:

1. Make sure the vacuum cleaner is on (the indicator is white or blue).
2. Find the Bluetooth or Wi-Fi/Bluetooth button (usually located next to the power button or under the lid).
3. Hold it for 3-5 seconds until you hear a beep or see a flashing blue light.
4. Open the Mi Home app and start the procedure of adding the device – the vacuum cleaner should appear in the list of available ones.

⚠️ Note: Some models (e.g. Dreame) D9) If the vacuum cleaner emits a double beep after holding, it means resetting the settings, not activating the module.

Method 2: Enable via the Mi Home app (for vacuum cleaners with firmware 2022+)

If there is no separate Bluetooth button on the case, try activating the module software, which works for vacuum cleaners with firmware newer than 3.5.8 (check the version in the device settings in the application).

Step-by-step:

1. Open Mi Home and select your vacuum cleaner from the device list.
2. Go to Settings → Device settings → Communication.
3. Find the Bluetooth (or Wireless modules) and move the slider to the On position.
4. Wait for the message "Module activated" (can take up to 30 seconds).

🔹 If the "Bluetooth" item is not on the menu, then your model does not support software enabled. Try updating the firmware (section about this below) or use the button method.

Method 3: Forced activation through resetting (if the vacuum cleaner does not respond)

If the vacuum cleaner does not respond to the button and the application does not have the option to turn on Bluetooth, then a hard reset remains. This method will work on 100% of models, but reset all settings (room maps, cleaning schedules, etc.).

Instructions:

• 🔧 Find the discharge button on the vacuum cleaner body (usually it is recessed in the case and marked as RESET).
• 📍 Use a paper clip or toothpick to press and hold the 10-15 second button until the orange indicator lights up.
• 🔄 Release the button - the vacuum cleaner will emit an audible signal and restart.
• 📱 After the reboot, Bluetooth will turn on automatically. Connect to the vacuum cleaner via Mi Home as a new device.

⚠️ Note: On Dreame vacuum cleaners (e.g. Dreame Bot) Z10 Pro) resetting results in the blocking of zone cleaning before re-associating with the account. If you use this feature, save screenshots of the room maps in the application before resetting.

Method 4: Alternative AP connection (if Bluetooth doesn’t work at all)

If the Bluetooth module is damaged or disabled at the firmware level, you can connect the vacuum cleaner to Wi-Fi via AP mode, which works for all Xiaomi models, but requires manual adjustment.

How to do this:

1. Make sure the vacuum cleaner is on and near the router.
2. Press the Wi-Fi (or Bluetooth/Wi-Fi) button on the case for 5-7 seconds until you hear a voice message “Wi-Fi mode” or see a flashing orange indicator.
3. On your smartphone, open a list of Wi-Fi networks and find a network with a type name Xiaomi_Vacuum_XXXX.
4. Connect to this network (no password required).
5. Open the Mi Home app and add the vacuum cleaner as a new device – it will be determined automatically.

⚠️ Important: In mode AP The vacuum cleaner does not build a map of the room and only works in manual mode. After connecting to Wi-Fi, try updating the firmware - this can restore Bluetooth to work.

💡

If the vacuum cleaner does not go into AP mode, try to turn off mobile Internet on your smartphone and re-press the Wi-Fi button on the vacuum cleaner. Sometimes the conflict of networks interferes with the correct connection.

Solving Common Errors When Turning On Bluetooth

Even after successful activation of Bluetooth, users are faced with errors.-5 problems and ways of eliminating them:

• 🚫 Mi Home: Conflict with other Bluetooth devices (earphones, fitness bracelets) Solution: Disable all other Bluetooth devices on your smartphone and restart the vacuum cleaner (hold the power button for 10 seconds).
• 🔄 Bluetooth turns on but immediately shuts off Reason: Low battery charge (less than 15%).Solution: Charge vacuum cleaner to 100% and try again.
• ⚠️ “Bluetooth unavailable” Error Cause: Outdated firmware or software failure Solution: Update firmware through Mi Home (Settings section) → Update of the PO).

🔹 If nothing works, try reinstalling the Mi Home app and adding a vacuum cleaner again. In 30 percent of cases, the problem lies in the app's cache.

How to update your firmware if Bluetooth is not working

Outdated firmware is one of the main causes of Bluetooth problems. If the vacuum cleaner is not connected via Bluetooth or Wi-Fi, update the software manually:

Instructions:

1. Download the latest firmware for your model from the official Xiaomi website (Support section).
2. Unpack the archive and rename the firmware file to vacuum.bin.
3. Copy the file to an empty microSD card (FAT32).
4. Insert the card into the vacuum cleaner (the slot is usually under the cover next to the reset button).
5. Turn on the vacuum cleaner - the update will begin automatically (the indicator will flash green).

💡

Updating the firmware via microSD is the only way to restore Bluetooth if the vacuum cleaner doesn’t connect to Wi-Fi and doesn’t respond to buttons.

⚠️ Warning: Do not remove the microSD card or turn off the vacuum cleaner during the upgrade (the process takes 5-10 minutes).If the indicator goes out ahead of time, repeat the procedure with the new memory card.
