1205 detail
All models, including the 1205, and models before down to the AF, used the standard round two prong electric system for the extension of power out to the power nozzle. Only some CB used a three wire system that is not compatible. The earliest of 1205’s just used an outlet below the hose opening on the bag door with a pigtail hose end or an external wire wrap around the hose. At the handle end, most 1205s used a metal handle and the outlet was dual sided at the transitional collar between the handle and hose material. This was paired with a blue sheath on the power nozzle wand that had the a longer sheath cord that ran through it and exited several inches below the top and hung there and one had to plug the sheath cord into the outlet on the hose collar. An early version of the automatic connection was made on those early 1205s similar to the handle and sheath system that was reintroduced on the Golden Jubilee and is still standard today on the Aerus Lux Classic, but it didn’t fare well, the power nozzle wand was plastic and the lower section steel and the plastic section tended to crack. It was telescopic with two settings, fully retracted or fully extended. It was quickly scrapped for the steel reinforced version.
