This is my 3rd robot vacuum. It is INSANLEY quite. The only issue I have is that it is a little tall and doesn't fit under some furniture. It will go under beds and desks, but does not fit under the dresser. It does fine all over the house. The compartment that holds the dirt that was vacuumed is very large. It really never Bumps into anything, it gets very very close but doesnt bump your furniture. I would recommend trying the Samsung Powerbot to anyone
