Patent ID: 7314553

Claim:
A pool filter cleaning device for capturing contaminants of a dirty pool filter, the pool filter cleaning device comprising: a containment chamber having a upper end, a lower end, and a circumferential sidewall extending between the upper end and the lower end, the sidewall having a water deflecting portion adjacent the upper end, the containment chamber adapted for receiving the dirty pool filter through the upper end for cleaning, wherein the sidewall is formed from at least one flexible material, the containment chamber further comprising at least one coil spring in communication with the sidewall biasing the containment chamber to an expanded configuration, the coil spring having a top coil adjacent the upper end of the containment chamber and a bottom coil adjacent the lower end of the containment chamber; a contaminant trap in communication with the sidewall for capturing the contaminants of the pool filter when water is delivered into the upper end of the cleaning device, the contaminant trap being sufficiently porous to allow water to pass through while substantially preventing diatomaceous earth from passing through; and wherein substantially all of the water delivered into the upper end of the cleaning device passes through the contaminant trap and out of the containment chamber.
