I am curious about the damage that may be caused to vacuum motors by water entering them, although i can understand that introducing water to an electrical part is very bad, if the vauum motor does survive this, what other damage can it cause, does it remove the lubrication of the fan or other parts it comes into contact with causing it to later fail,not being in the slightest bit technical as you have probably worked out already :

i would have thought that moisture must enter the vacs to some degree anyway.
Would spraying something like WD40 into the vacuum be beneficial or am i being a complete
idiot
