I'm still new so bare with me. Ok here is the problem. I mow this account that has a fairly large pool in the backyard. I bag the grass and clear off any clippings left from trimming away from the pool. But for some reason grass still gets into the pool. (When i leave there is no grass in water, just later in the day) I have not seen how much grass has been blown into the pool myself but by the way these people described it..... Now these people are very picky.... In fact they are Lesbians - I've had a hard time pleasing any older lesbian couples.
