Most Hoover vacuums are equipped with a beater bar, which is a bar located within the head of the vacuum that gently taps, or "beats," the carpet as you vacuum. This allows for more dirt and dust to lift out of the fibers, leaving you with a cleaner floor.

HEPA stands for High Efficiency Particulate Air. This refers to the filter of the vacuum and the requirements that it must meet in order to be HEPA certified. This certification requires that the filter is able to capture 99.97% of 0.3 micron particles that are passing through the filter. These particles are so small that they are about 300 times smaller than a human hair.
