Query: Too heavy,not easy to use

This vacuum looks nice, the only nice thing I can say about it. It weighs 30 lbs. Pretty heavy for taking it up and down stairs and no easy way to carry it. The bags don't hold very much. The bags have to be changed out every couple a weeks. The height adjustment light went out right after I got it,so you have to guess where the brushes are. Too expensive a vacuum for what you get.
