Abstract
A hydrodynamic attachment for use with a pool brush having scrubbing bristles at a brush head portion connected to an elongated pole. The hydrodynamic attachment has a base fin connected to the pool brush opposite the scrubbing bristles, and an outer fin connected to the base fin to form a scoop pocket. The scoop pocket has a generally C-shaped cross-section such that the scoop pocket can temporally trap water when the pool brush is pushed in a downward motion. In this manner a transverse force is produced against the brush head which is then urged toward the target surface of a pool. Additionally, an improved pool brush which incorporates the hydrodynamic attachment is disclosed.
