No way its just as Draper said about the Zipper its no fad.
A shift, its a paradigm shift. Its foolish to think the wand with its minor changes over the last 50-years is tool of choice. Look at how everything else we use has changed in time.
RE's are here to stay,
they clean better those without them can come up with millions of reasons why they don't need one but the honest truth is a person, any person cannot sling a wand and expect results anywhere near that of an RE. Sure you can do things to improve your results over "just a wand", use a Cimex,
CRB, 175 & floor pad but its more time & more labor just to try to equal that of an RE.
The modern RE is lighter so its easier to carry in & out of the van, yet doesn't compromise any on its effectiveness. They kick ass and are a "must have" in the residential setting.
