This vaccum is great!!  It cleans much better than my old Panasonic and gets the corners and edges without going back.  Easy to use and easy to dump the dirt collector.  You do need to adjust manually for carpet floor height and it does not have a light.  Otherwise it still cleans quicker than my old one, is lighter and doesn't seem to try to grab things like curtain edges or cords.  It pushes them away instead.  The wand detaches quickly for getting those narrow spots and both the wand and dirt collector are easy to remove and replace.
