ABSTRACT:
A floating, multi-directional liquid skimming device, comprising a perimeter frame attached to a net, where the frame rotates relative to a central axis. A central axis element may be attached to a pole handle. Floatation elements can be located along the central axis. In operation, the frame floats at rest with the frame roughly parallel to the surface of the liquid, and where the top edge of the frame is above the liquid surface to retain collected debris. When the device is pulled toward the operator, the frame swivels relative to the surface, so the frame opening is facing the direction of travel, enabling capture of floating material. When the skimmer motion is stopped, inherent floatation causes the frame to quickly swivel back to the resting position. If the skimmer is pushed away from the operator, the frame opening swivels to face the new direction of travel.
