When I saw this for the first time, I thought "the little thing won't be of any use". I was wrong. This little guy is awesome. The first thing I did was clean the computer case. By removing the handle I was able to easily put it under my desk. He pulled out any dog hair, pennies, dimes, and cigarette butts that had fallen inside. Once I was done, emptying the unit was a breeze compared to my big vacuum. My back hurts and this baby is light. Just perfect.
