I had one of these ..
That I traded in when I sold Kirby machines. It was complete with a portable handle small shake out bag, and red power cord with a switch built into the machine end of the cord, and full set of canister attachments. I have always liked Royal and had never heard of Electro Hygiene before this one. I assumed it was a Royal rebranded for a store like Sears and Monkey Wards used to rebrand their machines from other makers. I was also shocked that they had made the belt lifter and removable nozzle like Kirby. This is the only one I have ever seen, and have never seen the Royal counterpart. I assume Kirby came along and sued them over this obvious patent infringement, otherwise I'm sure they would be more plentiful.
