Here is my Lux Royal D790. Lux appliances were sold direcly from door to door. This modell was built mid 90's by Electrolux in Sweden. It has a 1100 Watt motor with a button for 3 settings: min/max/automatic speed control. As standart it came with a large, high density microfilter, but could be upgraded with a premotor Hepa filter.
I like very much the design ant the automatic features.
