Outdated models like the Xiaomi Mi Robot 1st generation (2016) may not support modern versions of applications, but they will require a rollback to old firmware or the use of alternative applications like Valetudo (for open source firmware).
Preparation for connection: what to check before pairing
Before you connect the robot vacuum cleaner to your phone, make sure all the prerequisites are met:
Download the latest version of the Mi Home app (or Roborock/Dreamehome for the respective models)
Connect your phone and vacuum cleaner to a single Wi-Fi network (2.4 GHz!)
Make sure that the vacuum cleaner has enough charge (minimum 20%)
Check that geolocation and Bluetooth are enabled on your phone
Turn it off. VPN Antivirus (they can block the connection)-->
Critical requirements for Wi-Fi:
- 📶 The network should be running at 2.4 GHz. Xiaomi vacuum cleaners do not support 5 GHz (even if your router is dual-band).
- 🔒 The network password should not contain Cyrillic symbols or special signs such as @#$%. Use only Latin and numbers.
- 🌍 If you are in Russia, install the region in the Mi Home app to China (Mainland China) – this will solve server problems.
Important: Roborock S7 and newer require a firmware update before the first connection. If the vacuum cleaner flashes red, download the latest version of the software through the official website.
💡
If your router can’t separate 2.4 GHz and 5 GHz networks, create a guest network only at 2.4 GHz specifically for smart devices.
