Hmm, well, trying to find an earth on the cleaner. Modern cleaners seem to
be made of plastic, at least externally.

You probably won't find one - they're all double insulated nowadays.

If you did find one, you want to put something like a 1Mohm resistor
in series, so that whilst it can bleed away static, it can't pass
enough current to act as a path for an electric shock.

What I don't get really is why one
cleaner should be worse than another.

It will depend what materials are used. The friction between fast
moving air and some plastics will generate static, as will running
some plastics on various carpet materials.
