Abstract
A utility vacuum that may be configured to employ a disposable bag or removable and reusable container for the collection of dirt and debris that are drawn into the utility vacuum. The utility vacuum may employ one or more movable legs that are movable between an extended position, which provides relatively stable operation of the utility vacuum, and a retracted position, which reduces the footprint of the utility vacuum so that it is easier to store.
