How to upgrade or reflash the robot vacuum cleaner Xiaomi: official and alternative ways

Xiaomi’s robot vacuum cleaners are not just smart cleaning machines, but full-fledged gadgets with their own software. Like any smartphone or tablet, they require periodic firmware updates to correct errors, add new features or improve navigation algorithms. However, the process of firmware vacuum cleaner is significantly different from a smartphone update: there is no universal solution, and errors can lead to a complete loss of functionality of the device.

In this article, we will look at all the current ways to update firmware for Mi Robot Vacuum, Dreame, Viomi and other Xiaomi lines, from official methods through the Mi Home app to manual stitching through ADB or specialized utilities. We will focus on the risks faced by users when using informal firmware, and give a checklist for a safe upgrade. If you have never flashed smart equipment before, start with official instructions and only then experiment with alternative methods.

Why you need to update the firmware of the robot vacuum cleaner Xiaomi

Manufacturers are releasing software updates for robot vacuum cleaners on a regular basis, and this is not just a marketing ploy. Each new firmware version can:

• 🔄 Fix critical bugs that cause the vacuum cleaner to get stuck, build a map incorrectly, or fail to return to base.
• 🗺️ Improve navigation: more accurate mapping, better obstacle recognition (e.g. for models with LiDAR or cameras).
• 🔋 Optimize energy consumption by increasing battery life.
• 🛠️ Add new features: zoning, room cleaning schedule, integration with voice assistants.

For example, in the firmware for Xiaomi Mi Robot Vacuum-Mop 2 Pro version 3.5.8_004026 The drop sensor bug was fixed, which caused the vacuum cleaner to refuse to clean on dark surfaces. D9 Support for automatic suction power increase on carpets.

However, not all updates are equally useful. Sometimes new firmware versions can impair performance (for example, due to optimization for other regions) or remove useful features (as was the case with the hand-off in some versions for Viomi V3). So before updating, you should check the feedback on forums like 4PDA or Xiaomi Community.

Official ways to update firmware

The safest method is to upgrade through the Mi Home app (or Dreamehome/Viomi Home for the respective brands), which is automated and minimizes risks, but has limitations:

• 📱 Requires stable Wi-Fi connection (some models only update via 2.4GHz).
• ⏳ It can take anywhere from 10 minutes to an hour depending on firmware size and internet speed.
• 🔒 Updates are delayed for different regions (for example, European versions sometimes get firmware later than Chinese ones).

The following steps are taken for Mi Home:

1. Open the Mi Home app and select your robot vacuum cleaner.
2. Go to Settings → About the device → Update firmware.
3. If a new version is available, click Update and confirm the action.
4. Do not disconnect the vacuum cleaner from the power supply and do not interrupt the connection to the Wi-Fi until the process is complete.

For Dreame models (e.g. DreameBot D10 Plus), the path may be different: Device Profile → Cog sign → Software Update.

Make sure the battery is >50%|

Connect the robot to a 2.4 GHz network (not 5 GHz!)|

Close all background apps on your phone |

Check the available space on the phone (need ~500 MB)|

Shut down. VPN (It can block Xiaomi servers)-->

⚠️ Note: If the Xiaomi robot vacuum cleaner has stopped responding to commands after upgrading via Mi Home, try resetting it to factory settings via the Reset button (usually located under the housing cover).In 80% of cases, this solves problems with "hang" after the update.

Manual firmware via USB (for advanced users)

If the official update is not available or you want to install custom firmware (for example, to unlock hidden features), you can flash the robot through the device. USB-This method is suitable for most models based on the Rockchip or MStar platform, but requires caution.

What you need:

• 🖥️ Windows computer 10/11 (Some utilities need drivers).
• 🔌 Cable USB Type-A → Micro-USB (or Type-C, depending on the model).
• 📁 Firmware in.img or.bin format (download only from verified sources!).
• 🛠️ RKBatchTool (for Rockchip) or Mstar Upgrade Tool.

Instructions for firmware through RKBatchTool:

1. Download and install RKBatchTool.
2. Connect the robot vacuum cleaner to the computer turned off (hold the power button for 5 seconds to completely shut down).
3. Press the Reset button on the vacuum cleaner body and, without letting it go, connect the cable to the vacuum cleaner. USB-port.
4. In RKBatchTool, select the downloaded firmware file and click Upgrade.
5. Wait until the process is complete (the robot will restart automatically).

⚠️ Attention: Firmware through USB It resets all the robot settings, including the stored room maps. If you use custom firmware, you risk losing your warranty and access to official updates. For example, after installing Valetudo on Xiaomi, some users have faced blocking cloud features in Mi Home.

Firmware via ADB (for experienced users)

The ADB (Android Debug Bridge) method is suitable for robot vacuum cleaners based on Android Things or modified firmware like Valetudo, which allows you to install firmware without disassembling the case, but requires pre-activation of the developer mode.

Advantages of the method:

• 🔓 No need for a physical connection (works over Wi-Fi).
• 📥 You can install partial updates (for example, only the navigation module).
• 🔄 Possibility of rollback to the previous version of the firmware.

Instructions:

1. Activate Developer Mode on the robot: Press the Home button on the case for 5 seconds. In the Mi Home app, go to Settings → About device → Software version. Press the software version 10 times until the message You become a developer appears.

ADB

adb connect [IP- robot address]:5555

(IP can be found on the router or through the Fing app).

adb push firmware.img /sdcard/

adb shell su -c "flash_image recovery /sdcard/firmware.img"

adb pull /dev/block/mtdblock0 backup.img

This will help to restore the robot if something goes wrong.-->

Castom firmware: Valetudo, OpenMower and others

Xiaomi’s official firmware often limits the functionality of robot vacuum cleaners (e.g., block manual control or limit suction power).

• 🚀 Unlock hidden settings (for example, increase speed or turbo power).
• 🌐 Remove the binding to the cloud Xiaomi (work without the Internet).
• 📊 Get advanced statistics (detailed cleaning logs, sensor status).
• 🔧 Integrate with Home Assistant or other smart home systems.

The most popular custom firmware is Valetudo, which supports most Xiaomi/Dreame/Viomi models and is installed via a Web interface or SSH.

• ⚠️ Loss of warranty (manufacturer may refuse repairs).
• 🔌 Risk of “bricking” (if you interrupt the process or choose the wrong version).
• 🔄 No automatic updates (you need to monitor the releases of new versions manually).

Valetudo firmware on the MStar model (e.g. Dreame) D9) requires a preliminary downgrade of the official firmware prior to the version 3.5.7_003019 Otherwise, the robot may stop turning on.

💡

Custom firmware is only suitable for advanced users, and if you are not sure about your skills, it is better to use official updates or consult specialists.

Frequent Firmware Errors and How to Fix Them

Even if you follow instructions, you can have problems, and here are the most common mistakes and solutions.

If the robot vacuum cleaner has completely stopped responding (it doesn't turn on, charge, make no sounds), the loader may have failed, in which case only the firmware in MaskROM mode, which requires disassembling the body and closing special contacts on the board, will help. For Xiaomi Mi Robot Vacuum, these are contacts CLK and DAT (near USB-port).

How to roll back the firmware to the previous version

If the robot vacuum cleaner gets worse after the upgrade (for example, it builds a map worse or discharges quickly), you can return the old version of the firmware. However, rollback is not always possible - some Xiaomi models block downgrade through official channels.

Ways of rollback:

1. Through Mi Home (if available): Download the old firmware version from forums (e.g, 4PDA). Rename the file to update.zip And put it in the root. SD-Put the card in the robot, press the Reset button and turn on the power.
2. Through ADB: adb shell su -c "dd if=/sdcard/old_firmware.img of=/dev/block/mtdblock0"
3. Through USB (for a full reset): Use the RKBatchTool utility with the Restore option. Choose the old firmware backup (if any).

For example, for Xiaomi Mi Robot Vacuum-Mop P, the rollback from version 4.6.1 to 4.5.5 solves the problem with false positives of the dirt sensor, because of which the vacuum cleaner constantly reported the need to clean the brushes.

⚠️ Note: Firmware rollback on models with an MStar processor (for example, Dreame) Z10 Pro may cause sensor calibration loss. After a downgrade, be sure to recalibrate through the engineering menu (Home button). + Spot held for 3 seconds).
