In one embodiment, the pool cleaning device comprises a primary component having a tubular configuration and terminating in an angled configuration therewith. A secondary component is in fluid communication with a medial portion of the primary component and angled at between 15° and 30° relative to the primary component. The secondary component is coupled to a ball valve for restricting or allowing the flow of water through the device. When a telescopic pole and a hose are simultaneously coupled to the separate openings on the primary component and the secondary component, respectively, the device may be use to create high pressure flow to clean submerged surfaces or water surface debris with little effort exerted by the user. ## Claims ### Claim 1 A pool cleaning device, comprising: a primary component adapted to receive a handle, the primary component comprising: a proximal portion, a medial portion and a distal portion, the primary component allowing a high pressure fluid to flow therethrough, the medial portion integrally connected between the proximal portion and the distal portion;
