I wonder how long it will keep going for.
Me, too. As a young boy it bothered me a lot, probably because I am autistic and also because as a boy my ears weren't accustomed to hearing loud sounds yet. As I grew older, my fears for loud noises gradually subsided.I have become acustomed to loud vacuums. I no longer think a Kirby is loud.
So our big Rigid shop vac doesn't have a bypass motor per-se. When I finally took it apart to clean it I got a surprise. There is a fan built into one layer of a three layer plastic upper housing. Dirt and water that get past the filter or float can impinge the fan and indeed it was very crudy inside, but the motor is in another layer of the upper cover driving the fan through a shaft. It is not a single one piece vacuum motor. The fan housing is molded into a layer of the upper housing.Shop vac by Alliance/Genie, and Rigid/Home Depot with bypass motor. Emits an awful whine under load.
My previous home had a big Mastercool evaporative cooler. I would suck the water out of it with the shop vac. Before that I used a hand pump and a big bucket. The fall ritual in the high desert was draining, cleaning and winterizing the swamp cooler.Our Rigid is a smaller model, and has never been used for water. Only sawdust on the table saw.
