I run it in the following mode: During the day, the robot vacuum cleaner cleans me everywhere, and in the evening, when I come home from work, I launch Brava into the bedrooms, then I put it on charge and run it on the rest of the area except for the bedrooms at night. Since it is almost silent, it does not interfere with sleep at all. It makes no sense to buy Brava if you don’t have a robotic vacuum cleaner, but if you already have a robotic vacuum cleaner, then you can buy it so that the cleaning is completely automatic, so to speak.
