i remember the guy had only highschool education, but with alot of imagination he invented the thing. it was meant for chicken waste disposal, as in you put in dead chicken to the windhexe and whirrr you get chicken powder. supposedly only works with soft stuff. if you put diamonds into the thing the windhexe machine will turn into powder

what it does is there's a huge blower on top and you put your stuff in, turn it on. the blower creates a tornado-like environment inside the windhexe body, which causes its contents to slam into the walls with ridiculous speed, gradually eroding them into powder.
