Bought this because the Shark that I wanted is no longer available.  Love that it’s cordless, hate that the battery life isn’t that great.  I feel like my older Shark had more power.  This one has a couple of different settings and that helps I just don’t feel like it’s as powerful as my corded vacuum.  The canister is also smaller but not so much that it’s a problem.  Overall I like it, just wish battery was better.
