To w1986...
The oem rubber hoses have the wiring built into them. Aerus//Electrolux started changing to this type in the late 90s as the old braided ones still never would last so they made the change to the rubber or vinyl hoses. Most of them you can see the wiring through the clear outer layer woven in on the ribs. The way you can tell an oem from a generic is look closely at the handle. The oem has the genuine handle with the round knob on the underside that you turn for the suction control. None of the generics have this round knob style for the suction control. There will also be little groves on either side by the round knob that are air vents. Some are stamped Electrolux on the handle as well provided they were made before 2003, once the name became Aerus they stopped stamping the Electrolux name on the handle and did not change it to Aerus but rather left it without a name. It can take some time to find a used OEM hose on eBay but Aerus does sell them new as well for all models back to the 1205. I’ve heard that they have discontinued producing the “pigtail” version with the small wire coming out at the machine end to plug into the power outlet on the older metal models such as the F, R, G, and L but also heard conflicting stories that it can be special ordered. All those models are over 40 years old now as the L was the last model that used that hose and went out of production in 1979. If they have discontinued even the option to special order this hose, seems they don’t want to support machines over 40 years of age. The metal bodied machines that use the next hose such as the 1205 through Ultralux series were made from 1968 to about 1995 so since they want to support the machines made in the 90s those use the same hose on several models back to 1968. I believe they may still make a non electric oem hose as well to fit the older models.
For people who have an old braided hose with the external wire strapped on, a replacement non electric hose can be used, eleven a generic...and the strapped on wiring can be transferred from the old hose to the new hose. The external wire should not be discarded if in good condition, they may no longer be in production either. Electrolux made both styles to get power out to the end of the hose. The fully electric hose was more pricey and an upgrade when they were first made for the next several years or the other less pricey option if one wanted a power nozzle was to just buy the external strap on wire for less cost and use it on the included standard non electric hose. I believe they offered this to fit various budgets as the power nozzle became more and more popular as an option before it was included as standard equipment in the 80’s. Models such as the 1205 could not use the non electric hose (the first year 1205’s could but after that none could) because they discontinued the little plug power port on the top of the line models in favor of the hose end with the two contact pins built into it that engage in the slots in the hose receptacle on the front of the machine. This “automatic” power connection style was introduced with the 1205. The plastic bodies canisters used a similar style of automatic connection which was the standard from the Canadian models and continued as the plastic bodied canisters essentially were the Canadian models and then the Renaissance and later top models use a prong style built in to the hose end. Today’s Lux Classic and Lux Legacy still use the plastic body machine end hoses from the Canadian design and the Lux platinum uses a style all its own.
With so many 1205s, Golden Jubilees, Super Js, Olympias, Diamond Jubilees, Marquises, Grand Marquises, Legacys, and Ultralux classics and Ultralux LXs out there still it would be foolish to discontinue the one hose that fits all these those machines even though all of these machines are over 25 years old now and a new oem vinyl hose is available from Aerus. They only sell the rubber/vinyl, no longer the braided style.
