Here is my Lux 1 Royal D820 which I bought in 1998 with the optional power brush ZE3. It has a 1250 watt motor, power setting for min/ max/ automatic control. This Lux models where sold from door to door. It has a premotor filter with charcoal layer to eliminate odors and an exhaust Hepa filter. It is one of the most quiet vacuum cleaner I ever used.
