How to sew a robot vacuum cleaner Xiaomi Mi Robot: official and alternative ways

The firmware of the Xiaomi Mi Robot vacuum cleaner is a procedure that can significantly improve its performance: from fixing bugs to adding new features like zoning or integration with Apple HomeKit. However, incorrect actions when updating software often lead to "bricking" the device, when the vacuum cleaner ceases to respond to commands or does not turn on at all. In this article, we will analyze all current methods of firmware - from automatic updates through the Mi Home application to manual reflashing through the app. ADB or SSH, We also tell you how to avoid common mistakes.

It is important to understand that Xiaomi Mi Robot models (including series) S50, S51, STYJ02YM Others have different firmware versions and installation methods, for example, Mi Robot Vacuum-Mop 2 Pro is available for an update via Mi Home, whereas older versions like Mi Robot are available for the Mi Robot. 1S You may need to have a handheld through USB-OTG. We will dwell in detail on each method, indicate compatibility with specific models and provide links to official and custom firmware.

If you've never done a smart firmware before, start with the automatic method, which is the safest way. For power users who want to unlock hidden features (like increasing suction power or disabling region-by-region restrictions), alternative methods will be suitable. But remember: informal firmware can take you out of warranty and cause the vacuum cleaner to run unsteady.

1. Firmware Preparation: What to Do Before Updating

Before you start firmware, make sure your Xiaomi Mi Robot is ready for the procedure.Neglecting preparation is the main cause of failure.

• 🔋 Battery Charging: Charge level must be at least 50%. Upon discharge during firmware, the device may fail.
• 📶 Stable Wi-Fi connection: To automatically update via Mi Home, you need Internet speeds from 5 Mbps. Use a router at 2.4 Hz - 5 Hz, many models do not support.
• 📱 Updated Mi Home app: Install the latest version from the App Store or Google Play. Older versions may not see new firmware.
• 🔍 Check the current version of the software: Go to the vacuum cleaner settings → About the device in the Mi Home application and write down the firmware version.

Also back up your settings if your model supports it (e.g. Mi Robot Vacuum-Mop P). → Settings → Backup. If you don't have a backup, it's okay, but after the firmware is done, you'll have to reconfigure the vacuum cleaner, including the maps and the cleaning schedule.

⚠️ Note: If your vacuum cleaner was purchased in China (version) CN), If you're using it in Russia or Europe, the firmware on Mi Home can block the device due to regional restrictions, and you'll need a manual firmware that removes the binding to the region.

Method 2: Automatic update via Mi Home (official method)

The easiest and safest way to do this is to upgrade through the Mi Home app, which is suitable for most models released after 2019.

1. Open the Mi Home app and select your vacuum cleaner from the device list.
2. Go to Settings (⚙️) → About the device → Firmware update.

After a successful update, the vacuum cleaner will restart and a notification will appear in the application. If the Update button is inactive, then you already have the latest version of the software installed.

💡

Automatic updates via Mi Home are suitable for 90% of users and do not require technical skills, but may not be available for older models or vacuum cleaners with a changed region.

If after the update the vacuum cleaner began to work worse (for example, poorly builds a map or does not respond to commands), try resetting it to factory settings. → Warning: This will delete all saved maps and cleaning settings!

Method 2: Manual update through USB-OTG (power-user)

If automatic updates are not available or you want to install custom firmware (for example, to unlock hidden features), you can sew the vacuum cleaner through the USB-OTG. This method works for most models, including the Mi Robot. 1S, Mi Robot S50 Mi Robot S51. You'll need it:

• 🔌 USB-OTG cable (Type-C or Micro-USB depending on the vacuum cleaner model).
• 💾 A flash drive. FAT32 up to 32 GB.
• 📁 Firmware file in.pkg or.bin format (you can download it on forums like this). 4PDA Xiaomi Community).

Firmware instructions:

1. Download the firmware for your model and unpack the archive. mirobot_v11_3.5.8_0000.pkg.
2. Copy the firmware file to the root of the flash drive (not to the folder!). Rename it to update.pkg.
3. Connect the flash drive to the vacuum cleaner through USB-OTG Adapter. Most models have a connector under the lid next to the power button.
4. Hold the power button on the vacuum cleaner for 5-10 seconds until you hear the beep, and then the refresh process will begin (the indicator will flash blue).
