I don't quite understand your question. Although the beeps are not supposed to be loud at night, can the Roomba run at night? The Roomba is anything but quiet and is rather annoying for us at night. In any case, as far as I know, you can't turn down the warning tones. Warning tones should be able to give a hint and make a sound accordingly.
