Thanks for the information, Doug. Very interesting .....
Maybe it's just me, but I have always placed a high priority on the design of attachments when I evaluate a vac. Most of the time, this part of a machine's functionality is ignored. Even my beloved Consumer Reports never tells you whether you are getting an efficient and useful set of tools with the unit they are testing. I suppose if the hose is a universal one, we can all attach better tools to the hose of a great machine. But it really goes against my grain to ruin a vac's "image" and "optics" with tools that weren't sold with it. Especially if the tool can't fit into the unit's provided tool holder, and if the colour is completely different.
Which brings up this question: Besides making money, why would Eureka allow a competitor to sell it's sleek and sometimes excellent attachments with their machines? I mean, if Eureka marketed their Vibra-Beat nozzles as something unique and "fantastic", (even though I hear they were really "much ado about nothing"), why would they allow a competitor to offer the same feature? More exactly, I love the classic Eureka floor and wall brush with that air-slot on the front row of bristles. For me, it might have made all the difference in deciding what vac to buy. So why would Eureka allow this to be sold with the Singer E12? I guess I am not much of a corporate maven, so I can't figure out why this would have been done so many times Eureka's history. I think even that grey GE handvac of the 1960's had Eureka tools in direct competition with it's famous blue "Whisk" vac.
