I had the triangle head. I guess I am off to the store for a new one of those. I really hate the moon shaped ones. I am not thrilled with triangle ones but atleast I can see through the plastic and know if the leaf was sucked in or not. The concesus appears to be move slow, very slow or all the debris floats away. I too "twist" the handle to get the larger debris under the head so it doesn't just push around. I will check out a few places and see if I can come up with anything else. If I do I will post back, if not then I am getting the triangle unit.

Thanks for the help and suggestions,
Brian
