My family is still using the Henry we got 14 years ago!
Since moving out, I've used a variety of cheapos and finally suck it up and went back with a Henry, granted it was post 1600watt era of Vacuum, so it's energy saving ones, it's still does the job!
Dragging the brush over the carpet and pulling out the hairs to be sucked back in beats having to use a pair of scissors to cut through the rotating brushes - I have 1 women in the house and I already get hairballs the size of several hamsters every fortnight. Last thing I want is to have them stuck in a rotating brush!
