This was my near-mint condition Electrolux 330 Automatic from 1973 that I sold a while back. It was a short lived model and ran from 1973-75 and was replaced by the 345. It featured an Automatic floortool that retracted its brushes when cleaning carpets and released them automatically when vacuuming hardfloors. It would also switch itself off if it became blocked or the bag got too full and the orange light would come on. The knob at the front of the machine controlled the sensitivity of this. My 330 also has a very rare optional Turbinette floor tool, it was an early style of suction driven power head. In the video I use it with a later style hose from a 302 model as the original weaved hose tends to lose a lot of suction now because of its age.
