I know it sounds crazy...but we had a huge hail storm recently! We are getting a new roof soon though, so yay! Anyway, when the hail came down it hit so hard that a lot of the little pebbles blew off the shingles and landed on the ground all around my house. A lot of it got in the pool because of how close the pool is to the house. My issue is that I can't get it out! I have a Polaris 9400 that is awesome. This thing picks up anything and everything. Even sand... and DE. But not roofing material. It just moves it around a little bit. I guess it's too heavy? I'm a little leery of brushing towards the main drains because if it's that heavy I don't want it to just settle in the bottom of the drain pipe. Short of strapping on the SCUBA gear and going down there with handheld broom and dust pan to sweep it up, any ideas? Has anyone dealt with this before?
