This is a replacement foam filter for wet use application for the Panther and the Predator gutter vacuums.
Please note: This filter does not fit the float valve of the GVS 3000 or GVS 3600 vacuum.
Care must be taken when removing and attaching the foam filter to the lip of the float valve housing to avoid tear.
You can watch how to fit the filter in this video.
The filter prevents larger clumps of moss and other solids from blocking the float valve during wet use.
