I've made a lot of mistakes in my time, but not enough to justify a power eraser!

An older model appears on pgs 201 - 202 in the 1930 Charles Bruning catalog. Three different colour erasers available! Each 7 inches long. You could erase alot. https://archive.org/details/generalcatalog00char/page/200/mode/2up
Very useful if a major revision was made to an engineering drawing during the pencil and vellum era. Helped prevent eraser wrist strain injury syndrome.
the TOP SECRET prototype plans of the dustbin fairing Land Speed Record 24 cylinder 50cc 4-stroke motorcycle was completely ruined when the motor eraser grabbed traction ripping the entire plan the shreds. so the went back to the drawingboard, to start aaaaaaaaaaall over again, from the git-go. but this time they have had already UP and learned their lessons and instead of that stupid motor eraser they will use at lot of this - youtube.com/watch?v=IaYdD7QdXIA

I used one of these for several years at my first engineering job, before I started using CAD. Very useful as noted above.

It was doing a burnout.
