Having moved house recently I accquired an old Henry vacuum cleaner that had been used for workshop and garage duties so was rather filthy but cleaned up well with soap & water.
However it was in a questionable electrical condition with a broken plug, missing cable strain relief and worst of all, an exploaded mains filter/RFI capacitor of the Rifa brand.

Remove a couple of covers and the electrical connections are revealed. The socket on the left is a passthrough for other domestic tools I think. In the middle is the failed Rifa capacitor and mains cable missing strain relief.

You can see the capacitor casing cracked wide open and there was burn marks/staining on the surrounding plastic. I bet this made quite an unpleasant smell when it went.

Old and new capacitors. The replacement is a modern Rifa capacitor. You can also see a 1 Meg Ohm bleed resistor attached to the old capacitor, I didn’t bother salvaging this and fitted a new one instead.

New capacitor soldered to the original terminals.

Fitted in position and you can also see the outer insulation of the mains cable correctly clamped.

Here it is cleaned up and fitted with a modern ‘turbo’ brush head, this uses the suction to also drive a brush head for a more thorough cleaning on thick carpet.

During my research I discovered this model was significantly older than I thought, being made during the mid 1980’s https://numatic.fandom.com/wiki/Henry#Henry_HVC200_(1983-1987)
