• 🔊 Sound signals and voice prompts

If you used Valetudo or custom firmware, adjust the basic parameters:

1. Open the Valetudo web interface at the address http://[IP_vacuumer].
2. Go to the Settings → Map and set up cleaning areas.
3. In the Manual Control section, check for response to commands (e.g. Start, Pause, Home).
