Triangular shape for easy cleaning of hardtoreach corner areas and pool bottom. The weighted head allows direct sinking to the bottom so cleaning can be completed efficiently. Flexible design with a small brush and swivel joint to access difficult corners and remove stubborn dirt with bristles. Made of special plastic material with increased weight to ensure the cleaning head fully sinks to the bottom, enabling thorough underwater cleaning and easy maneuverability. Universal installation: suction ports compatible with standard 1.2 inch and 1.5 inch suction hoses. The handle features a springloaded locking clip for easy connection to standard extension rods. Applications: suitable for swimming pools, sauna pools, aquariums, water parks, and landscaped pools, providing effective bottom and corner cleaning in various water environments. Use scenarios: Regular maintenance in inground or aboveground pools with steps and corners: reach around edges and clean the pool bottom where debris tends to collect. Cleaning smaller water features or spa pools and aquariums with tight spaces: the triangular head and swivel joint help access confined areas and corners. Cleaning larger or complex layouts such as water parks or landscaped pools: the weight and compatibility with common hoses and extension rods support efficient bottom cleaning across multiple zones. Key attributes: function (bottom and corner cleaning), compatibility (standard 1.2 inch and 1.5 inch hoses; extension rods with locking clip), size (triangular, weighted head), material (special plastic with increased weight), and performance (sinks fully for thorough underwater cleaning).
