ABSTRACT:
Leaves and other loose debris on a ground surface can be removed and collected by a portable vacuum that includes a motor-operated fan located at the upper end of an upright passage structure that has a lower intake end proximate to the ground surface. The vacuum is supported by two ground wheels at the lower intake end of the passage structure, and a shoulder strap attached to an upper section of the passage structure. The vacuum includes a rotary debris cutter in a mid area of the passage structure, and a centrifugal particle separation located between the cutter and the motor-operated fan.
