An apparatus for skimming floating debris from an enclosed pool of water wherein a circular current of water occurs, said apparatus comprising a frame defining an inlet portion positioned upstream and an outlet portion covered with netting positioned downstream. A collection basket, also covered with netting and located at one end of the inlet portion, extends upstream from and with its open end perpendicular to the inlet portion so that the leading edge of the collection basket sufficiently impedes the current along its permeable leading edge. This impediment induces a lateral current internal to the apparatus which causes a substantial portion of the floating debris entering the apparatus to be accumulated in the collection basket out of the main flow of the current, rather than accumulating at the netting-covered outlet portion of the apparatus. This lateral collection area with its accompanying lateral current flow improves the ability of the apparatus to prevent debris from leaving the apparatus once captured.

[ The invention claimed is:] [20.]20. A method for removing floating debris from a pool of water having an edge and a current therein, said method comprising:a. positioning adjacent to the edge of the pool a frame having an inlet portion generally perpendicular to said current and an outlet portion covered with a permeable material, said frame with a first end and a second end, so that floating debris is brought through said inlet portion by the current;b. positioning at said first end a collection basket covered with a permeable material providing a relatively low resistance to current flow therethrough and having an open end with a leading edge, said open end perpendicular to said inlet portion and facing said second end;c. inducing by the choice of said permeable material a secondary circular lateral current, whereby said permeable material impedes water flow through said collection basket sufficiently to cause a differential in current force between the current flowing across said open end and current flowing through said collection basket;d. collecting floating debris in said collection basket, the floating debris being urged into said collection basket by said secondary lateral current; ande. maintaining free flow of water through said outlet portion by means of said secondary circular lateral current which tends to bring floating debris accumulating at said outlet portion into said collection basket.
