Abstract: The computer keyboard dust vacuum is a vacuum cleaner attachment that sucks dust and debris out from under the keys of a computer keyboard. The computer keyboard dust vacuum includes a main tube, outer sleeve, end cap, and protective screen. The hose of a vacuum cleaner is configured to be inserted in the second end of the main tube to provide suction. The end cap, which is mounted on the first end of the main tube, has holes formed in it that allow the suction from the vacuum cleaner to draw dirt and debris away from the keyboard, through the holes in the end cap towards the vacuum cleaner. The main tube and outer sleeve combine to allow the user to vary the amount of suction provided by the vacuum cleaner to the end cap.
