I purchased this Vacuum nearly 2 years ago and honestly... I wish I had found out about it MUCH sooner! It is simply the BEST! The reviews speak for themselves:

Keep in mind, I have severe allergies so having HEPA filtration is a must. Plus it comes with a separate carry unit for stairs, blinds, sofas etc.
