Rotary Evaporator Cleaning
There's no further need to comment on the coffee maker, but you might give the following cleaning method for the condenser and the rotation tube a try: 

Note that you might want to first check whether this is in accordance with local safety regulations! 


Take a small or medium-sized (max. 500 mL) 2-neck flask (NS29 socket connects to the rotavap, NS14.5 socket is for your thumb) and fill it with max. 250 mL acetone
Hook it up to the rotavap, support it with your hand
No spinning :D
Start the vacuum pump
Close the NS14.5 socket with your thumb
Watch the acetone starting to boil under reduce pressure 
Rapidly remove your thumb from from the socket and let the acetone "spit" all through the rotavap
