The Roomba S9 can be pretty noticeable when it's cleaning. Our research shows that it produces noise levels around 65-70 decibels, kind of like a regular conversation or a standard vacuum cleaner.
So yeah, it's louder than quite a few other robot vacuums out there. Some folks say it can be a bit disruptive if you're trying to watch TV or chat nearby.
But on the bright side, its strong suction and efficient cleaning might make the extra noise worth it. If the noise is a big deal for you, maybe try running it when you're out or during times when it won't bother you as much.
