I must admit that I purchased the Dirt Devil Kone for its looks - I like the modern, cone shape that looks so sleek and "clean" - I hated having to "hide" my other hand held vacuum and always have to "dig it out" when needed.
This vacumm is always ready and at my fingertips. It does the job it is supposed to do - that is - to quickly and efficiently pick up little messes/spills - This is not an industrial power vacuum that is going to suck up every little microbe - it is, however, great for its purpose.
I have a big house, a dog, 2 growing kids and a husband - there are always "little messes"...
