Greatest invention ever. Bought a samsung a few months ago and couldnt be happier with it. Have a dog and cat and it gets the hair, changes speeds depending on the flooring type, and weaves in and out of furniture like its nothing. It is wifi controlled so you can tell it on your phone to get after it and it does or just turn it on when you leave and it cleans up and takes itself back to the dock. My wife loves it.
