Junior Deluxe
Although they look somewhat like the Dial A Matic, it is completely different as it is a dirty fan rather than clean fan cleaner. Its hard to define quite how this cleaner came about as the model was relatively short lived. made in France it was first introduced in around 1973 as the Starlight Junior with a bright red or dark blue front box. There was a headlight under the dust box (rather like later DAMs) and a light up bag full indicator near the bottom. It was the first example of a Hoover sold in the UK with a pan adaptor under the brush roll for maybe 60 years, and indeed this might never have been seen on a Hoover in the UK before.
It might have been imagined as a replacement for the long running Junior series which, at that stage, had been running some 15 years largely unchanged. But no, the Junior soldiered on beside it, both standard & Dirtsearcher.
Then in around 1977 it was somewhat de-featured losing the bag full indicator and the head light although you can still see where it was on the cleaner above. Now called the Junior Deluxe it was now in the cream/green colour above or all over canary yellow. Around the same time the "standard" junior was slightly modified with a hard bag version of that also appearing.
The Junior Deluxe disappeared sometime around 1981/82 (presumably to make way for the all new Turbopower series) whilst the standard Junior, still looking not too different from its 1958 predecessor, carried on until 1987.
Although it is a bit noisy, I have a Junior Deluxe identical to the one above and, as a carpet cleaner, it is absolutely excellent. It does a great job of cleaning and grooming the carpets but is considerably lighter and easier to move around than the DAM or even the Senior(Convertible) - I used one for several months as my daily driver before I moved house at the end of last year
