MOST vacuums are dc brush type motors so a "dimmer switch" would
control the speed - but you would need a "heavy duty" one because MOST
are only good for 600 watts, and the vacuum power does not decrease
linearly with speed (or sound output). In other words the vac will
suck a lot less for a smaller decrease in noise output.
