How to reflash the robot vacuum cleaner Xiaomi: official and informal ways

Introduction: Why update the firmware of Xiaomi robot vacuum cleaner?

Xiaomi’s robot vacuum cleaners are not just household appliances, but full-fledged smart devices with their own software. Like smartphones, they require regular updates: the manufacturer fixes bugs, adds new features (for example, improved navigation or support for voice assistants), optimizes battery consumption. But if the phone installs firmware in two clicks, then it becomes more difficult with a vacuum cleaner: there is a risk of turning the device into a “brick” if you act at random.

In this article, we’ll look at all the current flashing options for Mi Robot Vacuum, Viomi, Dreame and other Xiaomi lineups, from official updates via the Mi Home app to manual stitching through ADB or SSH, with detailed instructions, warnings and tips for crash recovery.

1. Firmware Preparation: What You Need to Know Before You Start

Before you start the update, check out three key points:

• 📌 Model vacuum cleaner firmware for Mi Robot Vacuum 1S dreame D9 The sticker to the model is usually on the bottom of the device or in documents.
• 🔋 Battery charge. The battery must be charged at least 50% - when discharged during firmware, the device can fail.
• 🌐 Wi-Fi network. Official updates require a stable Internet connection (2.4 GHz, as 5 GHz many vacuum cleaners do not support).

Also prepare:

• 📱 Smartphone with Mi Home installed (version at least 6.0) or Dreamehome (for Dreame devices).
• 💻 Computer with Windows/Linux (You will need to manually run through ADB Available tools like Rockchip Batch Tool).
• 🔌 USB-Type-C or Micro-USB cable (depending on the vacuum cleaner model).

⚠️ Note: If your vacuum cleaner was purchased in China (version) CN), Global firmware can block the device. Check the region in Mi Home settings!

2. Official Update via Mi Home: The Safest Way

For most users, this method is optimal. The manufacturer tests firmware, so the risk of failure is minimal. The instructions are suitable for all models supported by the Mi Home (including the Mi Robot Vacuum-Mop P, Viomi V3, etc.).

Steps:

1. Open the Mi Home app and select your vacuum cleaner.
2. Go to Settings → About the device → Update firmware.
3. If a new version is available, click Update and wait until it is completed (usually 5-15 minutes).
4. Do not disconnect the vacuum cleaner from the network and do not close the application until the notification of success appears.

If the update button is inactive:

• 🔄 Check your internet connection (vacuum cleaner must be online).
• 📱 Update the Mi Home app to the latest version.
• 🌍 Make sure the region in the Mi Home profile matches the vacuum cleaner region (e.g. China Mainland for Chinese models).

⚠️ Note: Some models (e.g. Mi Robot Vacuum-Mop 2 Lite) reset their maps after the upgrade. save screenshots in advance or export data via Mi Home!

💡

Official updates via Mi Home are the only method that does not take away the warranty, and all other methods (including manual firmware) can be considered as interference with the software.

Manual update via USB: for power users

If the official update is not available (for example, for Chinese models in the global region) or you want to install custom firmware, you can sew the vacuum cleaner through the scalp. USB-This method works for most Rockchip chips (e.g. Mi Robot Vacuum-Mop 2 Pro) and some Viomi models.

What you need:

2. Format the flash drive in FAT32 and copy the firmware file to the root directory (not the folder!).
3. Turn off the vacuum cleaner, insert the flash drive into USB-port OTG) Hold the power button for 10-15 seconds until the indicator flashes.
4. Release the button and the refresh process will begin (it can take up to 30 minutes) and the vacuum cleaner will restart automatically upon completion.
