The Henrys Design is not the same internally as it used to be, to look at, one would think it was identical, however the 1988 HVR200 is VERY different to a 2015 HVR200 the moulding is entirely different, as switches and exhaust grills have moved places. To look at them from the front, they look pretty much the same, however, non of the internal casings are the same at all, the only thing they have in common is that they are both round, both have a smiley face and the name Henry printed on the front. That said the principle is the same and it is nice that the quality hasn't changed since 1988.
I guess I have owned too many Henrys!
I also find the Purepower a joy to use and I have always had a soft spot for them. I personally think the Purepower is the only thing worth buying from Hoover currently.
