In this recording, I would like to show the Polish vacuum cleaner Zelmer type 102 b, manufactured in 1981. It will require disassembly, cleaning and gluing damaged plastic parts. I will also show the RH5500A motor from the "Silma" factory, where worn brushes will need to be replaced. There will also be a bit of history and a few memories from the 80's.

In the recording, I used fragments of an article in "Zeszyty Naukowe" from 1975 about the RH5500 motor. The full text is available in the Digital Library of the Silesian University of Technology:
