A tool for cleaning debris from swimming pools includes a flame, a corresponding net, and retaining means for retaining the net on the frame. The preferred retaining means is an elongated strip of resilient, flexible material, having a generally U-shaped cross-section. The web portion of the cross-section includes an exterior surface smoothly shaped between its two edges to urge debris from the pool into the net. The leg portions of the cross-section include gripping portions to assist in engaging and/or disengaging the retaining means from the frame, to permit the net to be assembled, changed or replaced. The preferred frame of the tool is fabricated from metal and includes an elongated, curved frame portion with its ends welded to a tubular attachment member, to permit attachment of the tool to a handle, pole or similar structure. The preferred net of the tool includes one or more anti-slip devices to prevent the edge of the net or bag from slipping between the frame portion and retaining means. A corresponding preferred method of use is also disclosed.

[ I claim:] [1.]1. In a tool for cleaning debris from swimming pools, the combination of: frame means forming a mouth portion; net means covering said mouth portion; and retaining means for retaining said net means in operative relationship with said frame means, said retaining means having a first portion extending from said frame means when said retaining means is operably assembled with said frame means, said first portion including a front surface having a first edge configured to contact a surface of the pool and a second edge positioned rearwardly with respect to said first edge as said tool is normally moved through the pool water, said second edge being positioned inwardly from said first edge with respect to said mouth of said frame means, said front surface constituting a smooth transition between said first and second edges, and said front surface and said first and second edges being configured to scoop debris from said pool surface and direct it away from said first edge and toward said second edge, and thereafter into said net means; said net means including a body portion which permits pool water to flow through but traps particulate materials, said body portion having an edge folded outwardly over said frame means, said edge including anti-slip means to assist in retaining said net means in operative relationship with said frame means; said frame means includes an elongated, curved frame portion, said frame portion being operatively affixed to tubular attachment means, said tubular attachment means having a central longitudinal axis, said frame portion further having a rear portion including said first and second ends, wherein said rear portion extends generally parallel to a first plane that is coincident with said longitudinal axis, said frame including a forward portion having a generally rectangular cross section wherein said forward portion includes a front edge constituting a major surface of said rectangular cross section of said frame member that faces outwardly away from said opening, a second plane coincident with said longitudinal axis and perpendicular to said first plane, wherein a plane coincident with said front edge forms an acute exterior angle with said first plane as viewed in a direction normal to said second plane when in an un-flexed position.
