I have purchased about ten of these vacuums over the course of several years. My wife has used several and I have gifted most of them. My wife almost never uses her expensive, heavy corded vacuum as the AirRam does at least as good of a job and is light and easy to carry from room to room without the hassel of a cord. Our experience is that they last about five years of heavy use. When they wear out she always wants another one because of her great experience with them.
