Translations:Entstäubungspumpen – die ersten mobilen Staubsauger/2/en

Vacuum cleaners have a tradition stretching back over 111 years at BSH. In 1906, Siemens launched its first vacuum cleaner on the market with the so-called dedusting pump. This appliance was developed on the basis of the Siemens Elmo vacuum pump. It weighed 150 kg, had an upstream filter and was mounted on a movable sled.
