Definitely dry or worn bearings or the motor had some dirt deposited in it. My Shop Vac is due for a motor service (ironically only a few years old) and it sounds just like this. The warbling high-low pitch and the intermittent surges in motor loudness makes me think worn bearings, vibrating in the chase.

that sounds like a bent commutator shaft to me. and that would require a new armature. the fact your vacuum shop couldnt tell that vs a bearing problem is really sad. never use that vac shop again....
the before video was carbons out of proper seating and and a failing sealed bearing. it doesnt sound like your vac shop fixed the carbon issue either. | ||

usually a bent commutator shaft is caused by a sloppy vac shop tech in that vacuums past life before you got it. rarely they are that way from factory, but usually its caused by impatient shop tech using hammers to get bearings on or off.
far as the carbon seating you recent video showed proof i was right, however brief. i saw blue carbon sparks. it doesnt need to be a fireworks show to be out ot plane with the commutator. early signs of carbon wear will be a grinding noise like in your first video. re seating clean air motors is easy. a carbon seating stone will take quick fix of it. however it still sounds like the commutator shaft is bent. that slight out of line will ruin bearings with a vibration the motor wasnt meant to handle. the easiest way to tell if a commutator shaft is bent it to touch the motor bearings. if they burn your hand after use, that's the problem. | ||
