I got the Eureka Optima Lightweight vaccuum when I moved into my first apartment.  I like that it is lightweight since I live in a townhome and have stairs.  Also the attachments make it easy to clean tight spaces, like the crevices of the stairs.  The brush roll on/off option makes going from carpet to hard woods floors simple.  It is easy store and takes up very little space as the handle can be slid down into the unit for a more compact fit.  I also like that the handle has a circular shape on top which makes carrying the Optima up and down the stairs a breeze.  Not to mention it only...
