most convenient way to be held is by the plastic at the end of the flexible
tube, but on some surfaces, the touching of the metal pipe after a few
seconds not doing so produces an audible crack and a nasty shock.
I also have a Vax which uses the same arrangement, but does not have this

there hasto be a way to make the Bosh, which is lighter, work like the Vax
which is big and cumbersome, and I do not really want it for spills of

I did wonder about an inward facing corona discharge pin, or perhaps a bare

A length of extra-flexible flex as used for test leads, attached to the metal tube, spiral-wrapped round the hose to allow for stretchiness, and taken to earth on the vacuum cleaner body?

Antistatic hoses can be bought, but might not be easily adapted to a domestic cleaner.

A carbon loaded paint stripe would also work.

It can't be static electricity if it's jumping gaps and stimulating
your nerves and muscles. I don't find the concept of static
electricity as a separate entirety particularly helpful.

I blame the primary school teachers, the same ones who insist their
are seven colours in the visible spectrum.

It's called static electricty because it's generated on insulating materials
and hence remains there until either it leaks away slowly or it is provided
with a low resistance path. In this case, Mr Gaff.

Important in capacitors where the energy is stored in the insulating
material between the plates.

Spray with an antistatic spray.

Either one for the purpose, as used in electronics etc. Or similar stuff, sold
in the laundry dept as "anti-cling" (or even "anti-static") spray. Failing that,
diluted fabric softener, wiped on, also may be enough.

None of this will be as good as a wire, but may be enough.

OT: In the northern US, where winters are cold and houses very dry, we
used to have a dog who would come up behind us and touch her
nose to the back of one of our knees, and appeared to delight in the
reaction as the static charge caused the victim to involuntarily dance
as the knee collapsed in reaction. Who says dogs don't have a sense of
humour? She did.

Hmm, well, trying to find an earth on the cleaner. Modern cleaners seem to
be made of plastic, at least externally. What I don't get really is why one
cleaner should be worse than another.
I think its get out the rubber gloves time again. it was suggested that it
was me not the cleaner, but if that were the case it would affect me on the
other cleaner as well. Certainly I have had issues, changing the bed then
walking over to a large filing cabinet is not to be recommended.

Well, if we are being pedantic then, there is an imbalance of potentials
between myself and an insulated piece of metal on the cleaner.

One can easily make this occur in other ways merely with friction and even
with the friction of air itself if its dry enough, so maybe the real answer
is to turn my house into a rain forest humidity wise where there will not be
the ability for large potentials to develop.
Damn those electrons.
With regard to the visible spectrum, which I myself cannot see, that is a
whole other story of course. I used to wind them up asking so how do you
make silver and gold colours then.

The thing is of course that is it me which is storing it, or the vacuum.
Maybe its a naturist vacuum, and it would not happen if you do the cleaning
naked?
I'll suggest that to my female cleaner shall I? She gets the shocks as
well!
I have been reading up on this subject and its actually quite common. Of
course today for some reason its not doing it, so its hard to tell if any
system works.
The idea of conductive paint is interesting but not very practical, it will
wear off or break. The idea of a wire round the tube would not work as its
no a spiral tube its a sereies ofconcerteena constructions.
My feelings are perhaps a resistor on the person, and trying to remember to
touch this on things before more sensitive parts!

What is needed is a person with a high impedance meter.

Yes, insulating materials are where you notice it. If you have a
buildup of charge, then that creates a voltage, and an electric field.
This is true whether the buildup is on your hair or in the clouds. If
you are under a cloud where a large charge has built up, then the field
will induce a charge in you and your hair stands on end. If the voltage
difference gets large enough then the insulator may break down and you
get a spark or lightning.

You won't notice the same with a conductor as the charge can leak away
immediately.

Yes as do horses of course. Fun is felt by other animals.
Near me some years ago there was a field with horses in it. Most of the
time they would be well behaved, but one in particular had a way to wind up
dogs.
It would wait till the dog laid down, then sneak up behind it and poke it
up its bottom with its nose. When the dog got up and looked around for
anyone, it would obviously puzzled as the horse was busy eating grass, so
it would move a few feet and lay down again, and so it went on until
eventually the dog got fed up and wandered off and laid on the other side
of a fence.


Very strange.

The same dog of ours would be tormented by squirrels when we lived at a
place where she had to be kept on a lead outside the property, as it was
open-plan gardens, the ghastly 'Rolling Meadow' communal lawn system.
The squirrels soon learned exactly how long her lead was, and would sit
there just outside the range. We often thought about extending the lead
one day, but never did.

Funny, after that, she would kill any squirrel she could catch.

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.
