Also, I was reading one of your archived messages about your 1993 Philips looking like a Panasonic. Whilst I cannot say that the two companies were ever linked, I am 99% sure they weren't and certainly there were no overlaps in the cleaners. I can see though why you asked the question. It is all about fashionable designs, and the Hoover Junior De-luxe (Starlight) in the 1970's seemed to begin a trend for cleaners with the motors fitted to the bag section of the cleaner and not the cleaning head, with the controls mounted on the top of the bag unit. Other ones to do this over the years which followed were Hotpoint (which was a Bosch cleaner) and Electrolux 600 series, plus other which I would have to think about. Also many cleaners with the motors in the cleaning head also had the controls on top, like some Goblin commanders, Moulinex, Electrolux Twin Turbo. It is only the design which links your Philips to a Panasonic.
You will see that I said the Hotpoint was a Bosch cleaner. This is because Hotpoint had a 20-odd year love affair with Bosch and used Bosch cleaners and dishwashers with the Hotpoint name. Some were Bosch built and some products made under license. This was the same with your Philips cleaner, which was never made by Philips. I don't even know who made it, as the cleaner was used by no end of companies. The first I know of was Kenwood and Aqua-vac. Kenwood had two models which from memory was an electronic and none-electronic. The Aqua-vac cleaner dates back to the days before they merged with Goblin. The cleaning head was quite different from the standard head (like yours has) as it has scrubbing brushes for shampooing carpets, but the main section of the cleaner was the same. The only differece was that the Aqua-vac had a huge aeresol full of carpet shampoo stuck to the front. Note it was not a wet cleaner and the carpet cleaning method was shampooing not washing.
These cleaners were not seen for a couple of years, until Philips started buying them in for their own ranges. Next, a set of on-board tools were added and you could buy models with or without fitted tools. De-longhi also started buying these cleaners, as did some names you would never hear of again which related to specific catalouge companies. There were not a good cleaner at all and the build was poor. The handle and the chassis were prone to damage. Also there was nothing to lift the cleaning head off the carpet when using tools. This was all refelected in the lower than you would expect retail price.
