We've had this one for several years and I do really like it.

It recently broke (the head literally snapped off) so I need a new one. We don't have pets, but I do clean up hair a few times a month when I give DH and Son their haircuts and in general, this thing worked well. There are couple things I would want to change about it, but not so much that I wouldn't buy another one.
Before I did, I wanted to see if anyone had a vacuum that they absolutely love. I wouldn't want to spend much more than what this one costs. I have an amazeballs vacuum for the bedrooms and the rugs, so I need something specifically for the hardwood floors (the entire kitchen and living room and bathroom).
Any info is appreciated.
