Why change the voice of a robot vacuum cleaner and what does it do?
Xiaomi Vacuum Mop voice alerts are not just a nice bonus, but an important element of interaction with the device. The standard firmware of most models (for example, Mi Robot Vacuum-Mop 2 Pro or Xiaomi Robot Vacuum-Mop 2 Lite) comes with a Chinese or English voice, which is not always convenient for Russian-speaking users. Moreover, some owners want to personalize the robot by replacing the voice with a female / male version, adding humor or even writing down their own phrases.
Voice firmware allows:
- π£οΈ Change the language to Russian, Ukrainian or other (if localization package is available).
- π€ Set up a custom voice β from celebrities to synthesized variants (such as voices from movies or games).
- π Turn off your voice completely if it is annoying, while still keeping sound signals.
- π οΈ Fix playback errors when the robot βbubblesβ or phrases are cropped.
But the process isnβt as simple as updating software through the Mi Home app, requiring tools, firmware structure, and risk understanding, and improper voice firmware can lead to complete loss of sound or even a βbrickingβ of the voice module, in which case the robot will stop making any sounds, including error signals.
What Xiaomi Vacuum Mop models support voice firmware?
Not all Xiaomi robot vacuum cleaners allow you to change voice packets, depending on the hardware platform and firmware version. Below is a table of compatibility of popular models:
