Abstract
Methods and apparatus are disclosed for an improved underwater vacuum cleaning system. Urging elements are provided on a vacuum head to encourage debris, especially large pieces of underwater debris, to matriculate under the head or otherwise toward the vacuum opening, rather than traveling over the head or otherwise NOT toward the vacuum opening. Various embodiments of engagement elements are disclosed between the vacuum head and a vacuum hose to improve the connection therebetween.
