I got this a week ago and it’s wonderful. I don’t know why I waited so long to try a LG vacuum. It’s quiet and light. The best part is that it self empties. No more emptying the collection container over a dirty trash can. My hands can stay clean while this empties on its own in a minute.  The tower came pre assembled. The only thing you can to put together is the vaccum and it was super easy to figure out. It also comes with extra nozzle in the box. I am so happy with this vaccum. Will be recommending it to everyone!
