So the Hall Grindovac thread in the classified section jarred my mind into thinking about some more obscure vacuum cleaners from long ago. Things not labeled as 'vacuums' but having a main vacuum function built into them.
Below is the first thing I had thought of:

Little Giant electric chalkboard eraser cleaner

I have fond memories of this machine from my elementary school days. I remember watching the custodian running this machine on a nearly daily basis, always waiting for the occasional eraser that gets launched out of his hands.
I even used that machine on occasions when students were allowed to do so.

For those unfamiliar with them, you slide the erasers back and forth along the tray, the spinning black brush would dislodge the chalk dust, and the 2.5A vacuum would blow the dust into the bag.
I realized the bag must have not had fine pores, as the closet the machine was in was full of chalk dust of all colors.

I wouldn't mind getting one some day to put next to my Newcomb classrom record player, something else I have great memories of. I would then need to add a chalkboard and eraser, too so I could actually use it....
I guess I am just a nostalgic and sentimental old fool! :o)

On a side note, why did markers replace chalk? After being in corporate environments for decades, dry erase markers were usually dried out when you needed them (lots of landfill material). If a piece of chalk was on the tray, it ALWAYS worked, and could be used until you could no longer hold it! Also if whiteboards are not erased promptly, they would not even erase all the way..
More progress backwards?

If you know of other obscure vacuums of long ago, feel free to post about them!

chalk => marker transition...

I can't speak to this definitively, but the community college where I teach did away with the last of its chalkboards around 2009 or 2010. Part of that process was to install ceiling-mounted video projectors, using the whiteboards as projection screens. In that way, the whiteboards have an expanded functionality over blackboards. My only complaint is that the college cheaped out on the classrooms they retrofitted by installing whiteboards that are smaller than the chalkboards they replaced, and thus it becomes effectively an either/or choice as to which way to use them. All in all, I do not miss the chalkboards at all.
 
The reason they replaced chalkboards was I believe some unfounded hokey that inhaling chalk dust and exposure to chalk led to respiratory problems and cancer. Was never proven as far as I know.

I remember when I was in elementary school (this was the early millennium) kids were messing around with the teacher and took the erasers and just chucked them out the window when her back was turned (this was a 3 story school). The class thought that was a riot. Oh and the age old task of holding the erasers out the window and smacking all the dust out still went on into that era.

I think by the time I got to high school was the transition period of whiteboards (2008+). Some classrooms had them, others did not. All schools in my area now I believe have switched over to whiteboards. I remember for the past few years seeing lots of old chalkboards with school property stickers on them popping up in the thrift stores around here every now and again for several years.
 
Remember the chalkboard eraser vacuum from school days.Used one many times.Also chakboards were used in school during my school days.even thru college.For films,slides,overhead projector use there was a pull down screen on the maprail above the chalkboard.And of course those pull down maps.Have several I got from thrift shops and yes,yard sales.In my shop class made MANY wood cases for the pull down screens at the new high school-and installed them on the map rails in that new schoold-late 60's.
 
Chalkboard eraser vacuum - I seen one on eBay on Dec 24, 2020. I didn't buy it. Didn't have a use for it or they wanted too much money, I don't recall which.
