The Grit-Gitter Stretch is perfect for hot tub and spa spot cleaning with hard to get sand and dirt. It has the same great features as the Grit-Gitter with the addition of a 2'-3" long PVC extension pipe. If you notice grit after you're already sitting in your tub, don't get out of the water to clean it up. The Grit Gitter Stretch floats in your tub and is always at hand. It is great for vacuuming the filter compartment and can also be used to collect things floating on top of the water. It cleans easily. Just empty the contents outside your tub and rinse the screen.
