A system and method for extracting essential oils from organic material is provided. One embodiment places organic material into an extraction chamber that is a cylindrical wall of rigid material, wherein a diameter and a height of the extraction chamber is sized to define an interior that accommodates a desired amount of an organic material having essential oils; fills the extraction chamber with a solvent after the organic matter has been placed into the extraction chamber; and moves a vortex plunger disposed over the surface of the organic material in a repeated upward and downward motion during an agitation process so that the vortex vanes generate a fluid vortex in the solvent, wherein the fluid vortex causes the solvent to be drawn upward into the organic material and then to be pushed downward through the organic material so that the solvent extracts essential oils from the organic material.

A handheld vacuum cleaner includes a main body with a handle extending along a handle axis. The handheld vacuum cleaner also includes a motor assembly positioned within the main body. The handle axis intersects the motor assembly. The handheld vacuum cleaner also includes a dirty air inlet positioned at a front of the handheld vacuum cleaner and extending along an inlet axis. In addition, the handheld vacuum cleaner includes a cyclonic chamber in fluid communication with the dirty air inlet and the motor assembly. The cyclonic chamber defines a separator axis. The inlet axis and the separator axis intersect to form an acute angle extending between the dirty air inlet and the cyclonic chamber. The inlet axis and the handle axis intersect to form an obtuse angle extending between the dirty air inlet and the handle.
