iRobot Roomba 530 Robotic Vacuum Review

I am on my 4th roomba.  I originally received the roomba red for christmas many years ago.  I loved it, and was devastated when it died after 10 months.  iRobot replaced it, and the replacement worked for 10 months also.  I went for 5 months without one, and hated the way the dust hair built up between vacuumings.  My husband gave me a 530 for Christmas, and he bought it at Bed, Bath and Beyond.  After 17 months, the 530 stopped working correctly.  With my receipt in hand, I returned the product to Bed, Bath and Beyond, and told them it had stopped working.  They gave me a brand new roomba, no questions asked.  I am thrilled.  She said to bring that one back when it stopped working.  What a deal!  This is a way around the shorter than average life this product has.  The roomba keeps the hair from 2 dogs and the dust bunnies under control.  I do a traditional vacuum once every 2 weeks, and the house always looks nice.  I will not be without a roomba again.  I love it.  Easily moves from carpet, over throw rugs, over hardwood and linoleum.  I highly recommend it.
