(HPPOS - Hideous Plastic Piece Of S#!t!)

Isn't that made by the same company that makes the "pig" commercial vacuums?  I seem to recall seeing one in a shop once that sells a lot of commercial type vacs.

The first company to make a twin-motor upright was Air-Way — in 1936 with the Air-Way Scout, and then a second model in 1940, the Chief.*

Both of these Air-Ways have two motors — one for suction power and the other to drive the revolving brush. Unfortunately, neither machine was made for very long — not because they were not good vacuum cleaners, which they were, but because their motor-driven brush infringed on the Hoover’s patented beater-bar system and Hoover sued them.

The Air-Way uprights really are clever vacuum cleaners. They are easily converted for above-the-floor dusting by inserting a flexible cloth hose into the long handle which is hollow; then you simply turn the large dial in front to direct the suction up through the handle-tube and to the hose. They were also the FIRST vacuum cleaner to utilize disposable bags, made of cellulose fibers.

The photos below are of the 1936  Scout. The Chief is nearly identical except that the "power nozzle" housing is a bit more streamlined. These are not my photos; and I don't remember now whose they are. I've had them on my hard drive forever.

*Between the Scout and the Chief came the gorgeous streamlined machine, the DirtMaster, among the rarest of all vacuum cleaners.

It wasn't the revolving brush roll itself that Hoover had patents on; it was the metal agitator bars ON the brush roll. That was, at the time, a unique Hoover feature. Nowadays, of course, many makes have these with the Sanitaire being the most blatant copy of the original Hoover design.
