I love how easy it was to install on my wall to charging it. I did notice after I charged it for 4 hours the recommended time frame; it does not hold a charge at all. (It shuts off within doing my kitchen.) I do notice it picks up dog hair great off of a hard wood floor; however; on carpet it does not pick it up at all. If you don't have really thick dog hair like I do; this vacuum is for you. If you have more than one animal that sheds bad; this is not a vacuum for you.
