Grid device
The present invention relates to a filtering divider that helps create two regions of liquid cleanliness inside of a container. The liquid on top of the filtering divider will be cleaner than that below the filtering divider. This is achieved using a grate that is comprised of a plurality of grid elements. The filtering divider can optionally be arranged such that it may fold. In such a way, it can be placed in the bottom of a container and provide cavities for the storage of cleaning accessories.
