Bagless vacuum cleaner

Abstract

A canister vacuum cleaner is disclosed, which includes an exterior casing that has a top half and a bottom half. An interior area of the bottom half of the casing houses a motor that is configured to generate a suction force, which is ultimately transmitted through a tube and an appended flexible hose. By positioning the motor at the bottom half of the casing, the vacuum cleaner exhibits a more preferred and ergonomic center of gravity. The canister vacuum cleaner is bagless—and does not require the use of a disposable bag to capture and retain dirt and debris that the vacuum cleaner extracts from the environment. In some cases, the vacuum cleaner utilizes a first, second, and third means for cyclonic separation of dirt and debris.

What is claimed is: 
     
         1 . A vacuum cleaner, which comprises a backpack accessory that is configured to be worn by a person, wherein:
 (a) the backpack accessory is affixed to an exterior casing of the vacuum cleaner;   (b) a bottom half of an interior area of the casing houses a motor that is configured to generate a suction force;   (c) the vacuum cleaner is configured to employ cyclonic separation of air and dirt within the interior area of the casing; and   (d) the vacuum cleaner does not employ a disposable bag or cloth bag to capture and retain the dirt particles that the vacuum cleaner extracts from a surface.
