Sorry to be the bearer of bad news..
We've had that Royal vacuum in the UK under the Vax badge, but made simpler. Known as the "Maxima." Wertheim also brought it to the UK a couple of years ago with a PN but sales have been low, apparently.
I know it also sells in the U.S under Hoover and others.
For a straight suction vacuum, the Vax Maxima weighs nearly 8kg and I found it too heavy to lift as well as bulky to store. It also has a tiny 2.5 litre dust bag - HALF the size than Miele's near 5 litres on the S2.
I never understood why TTI made a Miele copy in the form of the Maxima - it looks very similar to a Miele S5, has the same dimensions, same power (2200 watts on the Vax) and yet has a tiny dust bag on board.
The PN on your Royal sounds rather good but if lightweight is a stronger consideration, the S2 is so much easier to handle and perfect for confined spaces.
