I bought this about 2 months ago after buying 2 other vacuums that were hard to push and couldn't handle our pets hair. The stratos is a very good vacuum,  compared to my Rainbow which I had for over 20 years the stratos is better on my body an I enjoy not having to refill the water. Don't get me wrong the rainbow is a great vacuum, I rate the stratos a 10. Would definitely purchase it again.
