This is the product you've been needing, the one thing that will fill the gaping void* in your pitiful, dirty life:
The USB vacuum-cleaner.
Yes, it's true: This remarkable device plugs into that incredible power-plant under your desk, also known as a PC, and vacuums up anything in reach of its magnificent 1200mm-long cable. The LEGO bricks on my desk thought they were safe from their natural predator, the rug-cleaning vacuum. Now they live in fear of their new, miniaturized, USB-powered predator.
* Technically this won't fill any existing voids... in fact it works by creating a new, tiny void, in a sense. But then it puts dirt into that void... leaving you with no net change in voids.
