Well why not, if you have an oil well in your back yard:-)
My wet or dry Shop vac, which I bought around 1975, and used for around
40 years until I decided it would never break, so I replaced it with a much quieter vac, still runs like brand new. I'll call it a shop vac because that's it's name and is what it actually is... and I'm not too sure how many $hundreds you have to over pay before it converts to a "dust extractor".And check this out, all the old hoses and attachments fit perfectly in my new, Ridged vac. No need to dig another well if I want more hoses and attachments:-)
