Sometimes he speaks softly. And sometimes loud. Although I did not regulate the voice. Apparently it depends on his mood. Doesn't bother me. By the way, if the filter is already clogged and you haven’t cleaned it, then it will go to the base to charge. That is, he will not say: clean the filter, but stupidly goes to the base. When I ate it, I just clean the filter, then the vacuum cleaner must be turned off and on again - to reset, as it were, an error. And he will clean up again. I myself could not put the program on the computer - MI HOME. But the support team helped me. He talked to me on the phone for an hour and a half. And here's another: the water supply is not regulated either mechanically or through the application. Well, in general, it is not critical. And so normal.
