Abstract

A handheld vacuum cleaner including a suction inlet, a main body, a handle defined by a portion of the main body, a motor disposed within the main body operating a suction source, and a filter coupled to the main body. The filter is configured to separate debris from a flow of fluid drawn through the suction inlet. The filter includes a housing forming a first volume and a filter media forming a second inner volume. The filter media is coupled to the housing such that the first and second inner volumes together at least partially define a collection container configured to store debris separated by the filter media from the flow of fluid. The filter further includes an inlet opening that extends through the housing to provide fluid communication into the collection container such that the flow of fluid with the debris can flow into the collection container such that the flow of fluid with the debris can flow into the collection container and a relatively clean flow of fluid exits through the filter media.
