So perhaps this is a basic question, but what are all of the brands manufactured by / engineered by Tacony, and what order do they fall in from lowest end of the range to highest point in the range?
Here is a list that had many of Tacony's brands. I would say that Riccar and Simplicity are at the top, Tornado and Powr-Flite are commercial vacuums in the same market as Sebo, Fuller Brush is their nicer "cheap" brand, and Carpet Pro is at the bottom. I believe only Riccar and Simplicity are made in the U.S.
In Europe, TruVox is also a Tacony brand. Tacony also owns Koala Studios which makes sewing room furniture for the Simplicity and Baby Lock sewing machines and sergers. CleanMAX is also a Tacony commercial brand, with the 8 pound "Zoom" models from CleanMAX made in St. James, MO. Many of the Tornado brand machines are also made in St. James.
