Battery Powered Handheld Computer Vacuum First, get this itsy bitsy vacuum cleaner with a little dust bag, 7/8" brush attachment, tiny wedge for getting in slots and narrow spots, and a bent arm attachment Next, stop eating cookies at your desk. Oh hell, go ahead and eat them--you've got a computer vacuum now! This tiny vacuum is great for lifting crumbs and dust off of hard surfaces but it can't pull jack out of anything plush, like carpet; it just doesn't suck enough. Measures 5" tall x 1-1/2" dia Runs on (4) "AA" batteries, which you supply, but you can use the money you saved on cookies.
