I like the Juniors, it's probably the only Hoover I actually like, they're light, they're manoeuvrable, the two I now have only use 250 Watts, and because they were a very common vac here, spares are everywhere (most made by Qualtex these days), so they're easily maintained to keep them going, and I've had 4 to date, a U1104 (Sold, pictured above and got a couple of youtube vids of that), a 1346 (Scrapped, the above & below pictured one), a 1334 and a 1334-lookalike rebuilt in the 90's by a Hoover dealer...
That said I'm thinking of selling off the 1334, mostly because it's still packed up in a box from moving across the country, I do like it, but, I just don't feel like keeping it...
As for hose use, I haven't a clue as I haven't got a toolset, but from what Jack (vintagehoover/DysonAnimal(?)) says on his website, it outperforms the Seniors with their tool converters fitted, as the Juniors work like Kirbys do in that you have a belt lifter adaptor that slots into the front, turn the dial and it removed the belt, and then slot your hose in and off you go doing your dusting...
Anyway, that Junior above didn't always look like that, when I got it it was a different colour, and was in very sad shape, it was a 1346, probably in it's Coffee & Cream colour, but someone with a tin of beige paint and a brush just slopped it all over the base of the vac, I did remove the paint, but the plastic looked awful so I sprayed it a Vauxhall metallic red (was going to be blue, but nobody stocked a blue I liked), which looked awful, and the motor gave out so, I left it behind when we moved, but the handle assembly, brushroll and some of the wiring lives on in my 1334-lookalike...
The picture is only half the story, the smell was terrible:
