I have this one too and so far have not killed it. It is about 4 or 5 years old now. It needs emptying alot but it is easy to do and frankly with as much hair as all my animals produce any vacumn would need alot of emptying.
I am now wanting to replace my bissell, this time I am thinking with a bagged version. The dust that comes from it when emptying the filter is just grossing me out. I don't remember this being an issue in the past. I really do like not having to deal with bags, but don't want to to be dealing with the major dust, I wonder if I am having those issues because it is just ready to be replaced, mine has to be about 4 or 5 years old too.
