We have only had our vacuum for a couple of weeks, so I can't speak to how it performs over time, but currently the suction is amazing that all of the attachments are very helpful.  We have all wood floors with area rugs and a hairy dog. I love the Auto feature moving from carpet to hard floors, and I love having my first cordless vacuum!  My house is much cleaner!  My only criticism is that the main unit is heavy and my arm gets tired when using just the attachments.  (I'm 63 and my arm strength isn't great).  It is very expensive, but I already think it is worth it as it will make my life much easier!
