Who spends a lot of time at the computer often eats at the desk. And no matter how much you take care, every now and then a few crumbs end up on the keyboard or the work surface. But it's not really worth getting the big vacuum cleaner and making a hell of a racket because of this tiny mess. This mini handheld vacuum cleaner should not be missing in any office or household. The Worlds Smallest Vacuum really works, has a reusable filter and removes dust, crumbs and other dirt effectively. It is recharged via USB, no battery is needed.
