My coffee grinder makes a terrible mess when grinding coffee. And the inside where the burr is located will get clogged with regular use, requiring a very messy cleaning process. I've thought about getting a small computer vacuum, but those things don't really have any suction power. I have a small Dyson vacuum and approached Revain about the possibility of micro-nozzles. Once you figure out how they fit together (check out the listing photos as nothing is included regarding instructions) I still don't know where any of the pieces fit into anything. It worked great removing most of the residue from the coffee grinder and what was stuck could be brushed off.
