I found a Vorwerk Kobold 120-1 in a thrift store. It's a German vacuum that is sold through a "family manageress" as they call it. This is a model from the eighties and it only has a flexible floor tool for light carpets and bare floors. The motor is only 250 Watts, but the suction is quite impressive. Most of the time these vacuums were sold with a powerbrush.
