The electric eraser cleaner

My classroom has old fashioned black blackboards on three walls, and the chalk dust has been getting out of hand. A couple days ago I took two erasers to the bathroom and beat them against the sink for a while, sending up clouds of dust and choking on it, and the morning after I wiped the board with a wet cloth instead. Upon which a student gave out the inside information: C-dog*, there's a machine for cleaning those erasers!

I had never heard of such a thing, and was fully prepared for this to be a little joke on the part of the student (she is funny). But a colleague confirmed that there was indeed an eraser cleaner, and pointed out where it was located, in a tiny, tiny closet containing this machine on a shelf and nothing else. It's this powerful little vacuum cleaner with a rotating brush, and it sucks the chalk dust into a ballooning green bag as it works. And it makes some noise while it's on!

My erasers are very clean now. Here's a picture of the machine. Isn't it the neatest thing?

*No idea where that came from - again, she is a funny student.

I wish my department had one of these. I've never heard of this before either.

Oddly, puffs plus work great as erasers. I'm not sure why, but it almost entirely eliminates chalk dust. For some reason, off brands don't work.

Machine is cool, but where to find one? I think I'll try puffs.

e, I wonder if these are even produced anymore! Next time I use it I'll see if I can find a production date.

Not sure I know what puffs are..? At the college I attended we used sponges. They rinse clean easily. Of course, the classrooms had running water for that purpose, but the rooms here do not.
