This blower makes a lot of noise and vibration. It's fine if used outside, but using it inside the house is a real pain. It bought it to reduce the dust during a bedroom remodeling. Not a working solution. The vibration shakes the whole house, and the noise makes it impossible to stay long in the construction area without ear protection. That being said, it can be used comfortably outdoors only.
