Query: I love it - I Hate it

When I began using this cleaner I was very impressed with it's cleaning and ease of use. Unfortunatly within an hour, the belt broke (they shipped a replacement belt with the machine). After replacing the belt, it ran great for about 30 min. then the brush arm literally melted and rendered the machine unusable, requiring service. Now I have to deal with the hassle of replacing the part and can only hope the new part(s) will somehow not fail as well.
