iRobot Roomba 550 Bagless Robotic Vacuum Review

I have my Roomba 550 for about 4 months now.  As a working wife with three dogs, two cats, a husband and an aunt all living under on roof I have dirt, dust and animal hair.  I bought my Roomba (I named her Marge) in hopes of not having to vacuumn every day.  At first I thought this was going to work out well.  I am disappointed though.  I have her programed to clean the entry, great room and kitchen.  These floors are tile, laminate and a couple of area rugs.  She can't get under the furniture, where dog hair loves to hide.  Also she leaves behind hair and lint on the edges of the rug. Another issue is that it is noisy. For a quick pick up she does okay.  I also wish that I didn't have to clean her so often, one run through these rooms and she is full!
