My last roommate had another well-known name-brand cordless stick vacuum, and after living with one it's something I can't live without.  It makes cleaning so quick and painless that just getting up from my work-at-home desk I'm inspired to do a quick vacuum.  The attachments on this blow the competitor away though---the spare battery is fantastic, since these things don't last long at high power, and I particularly like the rotating mop attachment.  My only complaint is that there isn't a separate stand or shelf for holding all of the attachments, so I currently don't have a great solution to keep it all organized.
