Bag Whistle Explanation

[paul]

The full bag whistle was a feature used by Eureka Williams on its TOL canned hams and by AB Electrolux on its TOL cylinders from the mid-'60s to the mid-'70s.

I'm wondering what other makes, if any, also used it how it operated.

Also, why was it discontinued?

It sounds like a a great concept to me (pun intended); although I have never heard one.

Old Panasonic Jet Flow canisters from the early to mid 1980s had a bag whistle too.

I-vac commercial machines have that too. Good pun.

Curiously, Eureka used different sound ports.

It seems that the Empress 1100-A was the first to be equipped with a bag whistle, yet there is no visible sound port on its control panel, and I was unable to see one in photos showing other views of the cleaner.

The later Vibra-Beat 1035-A—and possibly other model-types—had acoustic louvers on its control panel, and the Empress II model-types (1880-A, 1285-A, and 1286-A) appear to have a vinyl muffler over theirs. The Sweet Sixteens with control panels—that were unequipped with the bag whistle—also had the same vinyl rectangle sans the 'Audio Visual ' text leaving that to speculation.

Some nice features! It seems like a really good idea. Eureka had very nice machines.

Agreed!

They look so deluxe compared to what NZ had. Electrolux was always on the cutting edge of vacuum technology. That looks late 70s to me with the 6 suction control settings, at that point in time we had a bag full light, wheels and a cord winder as the new or last generation features.

Those suction control settings were just controlled air leaks. It didn't change motor speed. Eureka would not offer a means to change motor speed until the 1980s with the Vactronic series.

Oh, cool none the less, we didn't get suction control until the 90s.

That's actually a late '60s concept that was unveiled at the launch of the Empress II in 1970. And the company at that time was Eureka Williams—prior to 1974 when AB Electrolux purchased National Union Electric and Eureka Williams along with it.

Eureka's Brandywine canned hams (teardrop shape) TOL canisters were the last to have them as far as I know; and they were discontinued c.1981.

Interesting. Electronics that advanced that early.

My Panasonic Jet-Flo MC-6220 upright has one as well.

From what I have read here and elsewhere, AB Electrolux's Luxomatic ZC90, introduced in Sweden in 1964, was the first in the industry to use the technology with its "Whistle Stop Signal".

In the UK, the Z310 was the last to employ the feature; being produced from 1970 to 1973.
