I don't know of a tiny vacuum for this purpose. What I use is a tiny hose set:

This attaches to the nozzle end of most vacuum cleaners, including both regular vacuums and handhelds.
You can also use a regular vacuum cleaner hose by attaching a straw to a crevice tool with painter's tape. This doesn't work as well as the mini kit, but not too bad.
