If you have a lot of house to vaccum (or even a little) this is the elite unit to own. I've had mine for over 5 years and have never had a problem. Picks up anything, even shampoos if you have the attachment. The auto drive comes in helpful as well. Some might think it as an industrial vacuum and in terms of longetivity and durability it sure can be called that. But it's also a heck of a nice unit around 2400 sq. ft home like mine. Worry free!
