Amazing device, great vacuum cleaner. It comes with all the accessories you'll need. It has many different suction power settings. Easy to use up the stairs and not too heavy. It even has a quiet mode.
They don't supply any extra busy bags or filters, so you'll have to order those separately.
I think the only complaint I have, is that when you use it on carpet with a thick pile, it leaves lines all over the place, the brushes underneath must stick out slightly, that's just a bit annoying for my slightly OCD nature, hense the 4 stars. Other than that I'm very happy with it.
