I have had the Shark Vertex Pro Cordless Duoclean vacuum for a few weeks now and because there is a young puppy it is used at least twice a day. I feel that I made the best choice after reviewing all my options and reading a lot of reviews. #1 selling point for me was that it was a cordless vacuum that would stand up right on its own (used to have to lean the previous cordless and it would fall down). #2 charging base is separate and can be kept in a different area by itself (don't have to connect vacuum to charger). #3 is that it has 2 rollers including the soft roller for hardwood floor. #4 digital display that tells me how much battery is left, change between wood and carpet, change suction power #5 everything else ...just the right size and so easy to use.
