Carmine,
Here is James Dyson’s dual cyclone w/clear bin U.S. patent - filed in 1984.
.
Here and below is my Fantom Capture upright/dry shampooer, James’ 1st licensed American dual cyclonic w/clear bin and
U.S. patent - filed in 1987. It is my understanding that no other manufacturer pre-dates James’ clear bin. A clear sight glass yes, a clear bin no.
If any collectors know of any clear binned vacuum that pre-dates James’ clear bin I’d like to see it (post here). DIB
.
Note: Amway using Bissell as a manufacturer stole James' dual cyclonic and had on the U.S. market in 1990
(per James Dyson autobiography – “Against the Odds”) Read of it here
Hello DIB:
Eureka's first bagless upright, called the Whirlwind "cyclonic"
that was mass marketed in the USA was a single cyclone, not dual cyclone
like dyson.
WRT to the first clear dust bin, I mentioned recently that Regina used a
clear plastic dust cup on its later Electrik Brooms [probably late 1960's early 1970's].
So users could see the dirt in the cup for dumping.
Also Lewyt canisters, which were bagless and then went bagged in the
mid 1950's, used a paper bag called the Speed Sak that had a clear see thru panel
that extended the entire length of the bag. So users didn't have to quess if
the bag needed to be replaced.
Most if not all of the floor washers and scrubbers of the 1960's and 1970's used clear/cloudy
see thru plastic water tanks so users could see the levels of clean/dirty water
solutions.
Name brand canisters in the 1970's, like Sears, used clear see thru plastic covers for the tops
of the on-board tool storage so users could see that all the tools were present and properly
stored.
The application of clear/see-thru floorcare bins, bags, tanks and covers is not unique
to any particular vacuum brand, make, and/or model like dyson/dyson bagless vacuums. Their
usage has a long and storied history in the vacuum/floorcare industry in the USA dating
back several decades before Mr. Dyson.
