fit my old nilfisk and works like a charm
Your review: I have an older model of the GM 80, from the late 80's, early 90's that I inherited for my conservation work. The vacuum worked fine but the speed control was outdated (not slow enough). This one has very good speed control, the price is right, the only problem is that it is not possible to attach the box to my older model, the top casing is factory sealed. You can use the speed control without attaching it no problem, it's just awkward.
