I have a few duff vacuum cleaners, two of them I've been trying to make one
decent one out of, but never completed, and another one which is too far
gone to do anything with, anyhoo, I have a lot of vacuum spares knocking
about.
I'm not too sparkling on electronics, but I remember years ago that our
old hoover used to go on 'blow' instead of suck at the flick of a switch,
someone told me that if you wire a motor in the opposite way, IE connect
live to neutral and netral to live, it spins in the opposite direction,
although I've not tried it.
My idea is to make a minature blowing machine of some kind, for various
jobs and just for ****ing about with, so if I reverse the connections
around in the motor, will it do as I want and start blowing or will it
just blow up? - I'm not too bothered if it does the latter as I've got
quite a few, also, do I need to make this connection at the motor end or
can I just reverse the wires in the plug?

Or is it a non starter?

TIA

Wouldnt work. Even if you did contrive to reverse the motor direction, all
vacuums use at least a 1 stage, often 2 or 3 stage centrifugal fan which
just doesnt work rotated the other way!
