I purchased this vacuum two weeks ago. It is so difficult to use and not well made. I use this vacuum from one end of a 5000 sq ft house to the other changing several times from carpet to hardwood or tile. It is very difficult to use on carpet without raising the height of the vacuum to the point that it is not cleaning the carpet. I do not know why Hoover stopped making the self propelled vacuum! So much of this vacuum is plastic (I assume to reduce weight) and some of the attachments fall off during use. I don't think the plastic knob that is used to change the height will last very long because you have to use it constantly. The longer cord is an improvement but it needs to be attached to the top of the handle to stay out of the way. It cleans well on hard floors. I really miss the self propelled unit that I had purchased for many years! And, this one is more expensive!
