We had an old Dyson with a motorhead, which we loved.
When it finally died we bought a new Dyson with a "Turbo" head (not the motorhead) and it was the worst vacuum we've owned. Overpriced and useless. Sold it on eBay after a year of swearing at it.
Now we have a Hoover with a powerhead - as good (if not better) than our old Dyson.
