Long Fantom Story Short...
So to start with "fantomvacuums.net" wasn't the Fantom site. It was from a dealer at the time specializing in Fantom parts and refurbished machine sales, from what I remember at the time it was also associated with a now defunct Dyson online site called "Vacmall.com"
Before Fantom ever went bankrupt they decided to stop paying royalties to Dyson for use of his Dual Cyclonic technology. That led to the development of three machines in total, the Wildcat, the Crosswind 200XL, and the Crosswind 600XL. The Wildcat everyone here already seems fairly familiar with, so I'll skip that one for now. The Crosswind models were light blue in color with gray accents, and both were simply adapted versions of the Fury (200XL) and Cyclone XT (600XL). The 200XL was the later style Fury based on the Limited Edition and Special Edition Plus, both with styling updates as well as a changed out wand setup, it also had a specially adapted single cyclonic canister based closely on the design found on the Wildcat that came off as one piece, released by where one would normally find the carry handle on a Fury. The 600XL wasn't really much different from the normal Cyclone XT, just swapping color and getting the single/filtered cyclonic dust bin. Both models also dropped their HEPA filtration in favor of a series of foam based electrostatic filters that were supposed to last the "lifetime" of the machines. It also marked the first instance in which a Fury machine got a premotor filter beyond the simple fluff trap of old.
After the spectacular failure of these machines, along with the failure of the Calypso water filter Fantom/Iona ended up bankrupt. That is where the story of these machines begins. The Fantom naming rights and parts support production for the old machines went to Euro-Pro, who contracted out Sanyo to make bagless machines based on their own "Twister" line of products. The actual designs and production molds of the Wildcat and Crosswinds went to a company called "eSalton" who at the time had the rights to use the Westinghouse name on household products. With a quick name, color, and logo change for the Crosswinds they went into production with basically zero other changes and were called the "Westinghouse Wired" series. The Wildcat, for whatever god awful reason was chosen to be modified as a cordless machine running under the name "Westinghouse Unplugged" with the claim of having all the power and versatility of a normal vacuum, while being cordless and lightweight.
In the end, the Westinghouse machines much like the Crosswinds failed in the market. eSalton seems to not really be around in any form any more, thus parts and support are long gone. Same thing for the Fantom name and any parts or support availability from Euro-Pro.
That's basically the full story behind all these machines, it's pretty impressive how long the Fantom legacy and machine architecture actually managed to survive past the companies demise, and most likely would've lasted longer had it not been for Dysons quick arrival after.
