What can I say...I've bought four of these...two for us and two as gifts.  The oldest one is about twelve years old, and still working great with a replacement battery.  For many years it was basically our only vacuum.  Use it with or without the brush revolving...it works great either way depending on the surface.  Batteries hold their charge well and recharge fairly quickly (and they can stay on the charger all the time); the vacuum is extremely light weight and comfortable to use (at six feet tall, the handle is plenty long for me), and the company keeps making small refinements to an already excellent product that make it even more pleasant to use!  I love that you can use the charger on a table top to charge the battery pack by itself (it just pops out of the vacuum), or you can hang it on a wall and hang the vacuum on the charger without ever removing the battery (or even charge the vac with the battery still in and an extra battery at the same time!).  You can vacuum for days without having to clean out the holding box, but when you do, cleaning is quick and easy (if not slightly messy, but then you can't have everything...and what vacuum isn't a bit messy at cleaning time?).
