In this episode we will watch the construction of the historic German Progress 7 vacuum cleaner, most likely from the second half of the 1930s, manufactured at the Mauz & Pfeiffer factory in Stuttgart. This is another device from this company presented on this channel. We have already looked at the older Progress vacuum cleaner model 2 and the Electro Baby stick vacuum cleaner. This Progress 7 was recently presented at an exhibition at the Museum of Modernity in Olsztyn. It is functional and in nice condition. The surprise was the motor in this vacuum cleaner - very similar to the post-war motors used in Soviet Rakieta vacuum cleaners from the turn of the 1950s and 1960s. Most likely, Soviet designers copied this type of pre-war German devices. We will replace the brushes in the motor (size 6 X 6 X 15 mm). We will also see an interesting anti-interference capacitor from the Ernst Gross factory in Sömmerda (Thuringia), replaced in the vacuum cleaner apparently already in the times of the GDR.
At the end of the video, we will also take a look at another interesting vacuum cleaner from the Mauz & Pfeiffer factory, recently presented in Olsztyn - DeVo (Deutscher Volksstaubsauger), a witness to the dark pages of German history.
