Oh Bob,  u r my best friend.  Being a stay at home Mom for 15 years I just went back to work and school.  He is now my favorite child, JK.  He is a little louder than my friends rumba but u get used to it.  He does get stuck under on portion of my couch but no big deal.  The dust and pet hair that I pull out of Bob everyday is quite disgusting he does an amazing job and I couldn't be happier knowing that while I work at my computer he is cleaning up for me.
