If I'm correct the patent date of 1889 is not the vacuum cleaner but rather a music box, player piano or some other musical device, and most likely was in Germany.
That's right the vacuum cleaner was a later sideline. The type you have, a long cylinder on wheels and pushed via a long pole handle may or may not be the first. As I don't have my notes on hand, I can't say for certain which was first though I think it was a the two-person tank-style pumper.
While Regina started out in Germany, they relocated to New Jersey in the first years of the 1900's 02- to 07, or there abouts. Eventually they phased out the music box, player piano, and so on and went into vacuum cleaners as the main line of production. And in the late 1920's through the late 30's made a series of uprights. Then around 1948, they introduced a lightweight vacuum cleaner which was called the 'ElectrikBroom,' which took the country by storm. They also got into floor polishers, and a number of small appliances like can openers.
As I said, I don't have my patent, and other info with me so this is as close as my memory can get, but the backstory is quite interesting. Perhaps a few old-timers have some of my earlier notes and can fill in the details.

By the way, the name 'Caligula' refers to the cat in my avatar, he was the mascot for the V.C.C.C. circa 1986.
