I love, love, love this vacuum.  We recently adopted a 75 pound long haired German Shepard and he sheds like crazy.  My kids were covered in dog hair all the time and I was spending a fortune on tape rollers to remove the hair.  I did not have time to vacuum my entire house on a daily basis (who does).  We thought let's give the roomba a try but heard so many mixed reviews we were afraid to make the investment.  Finally, we couldn't take it anymore and broke down and purchased it.  WOW!!! No more hairy kids.  Now if you are looking for a vacuum that cleans that has outstanding performance...
