We live in Houston TX so our 2 big dogs shed constantly.  The home mapping was interesting to watch.  At the end of the first week, nothing was in the bin when I went to dump it out.  The vacuum was completely packed with dog hair.  This week, I've been cleaning the bin and pulling out the dog hair at the end of each day - that seems to help, but the long, bountiful dog hair seems to be too much for the vacuum to handle efficiently.  Saddens me, but it does a good job of keeping up with the floating hair, which is a plus.
