This was a Christmas present three Christmases ago.  I used it almost daily the first year and it worked well.  I found that I still had to got through with an upright and do some more intensive cleaning every week or two.  I have a large dog, so this vacuum has had a lofty challenge.  After about a year it stopped working great and I think if I sent it in to the company it would work well again, but I am too cheap to do that.  I took it apart once and cleaned it out.  It worked better for a while after that, but I would not recommend doing this unless you are familiar with electronics. ...
