1. This product is exquisitely crafted, featuring a round and smooth design. Its sturdy structure ensures your hands remain unharmed during use. 2. Special Design: This specially developed vacuum attachment releases pressure when laying vinyl pool liners. If the vacuum surface becomes blocked or sealed on the pool floor, its dual safety valves can release suction, reducing the pressure from the filter pump and preventing the vacuum from pulling up the pool liner. 3. Wide Range of Applications: This product has versatile uses and can be employed in various locations, such as swimming pools, floors, walls, etc. Simply connect it to a suction device using a hose for efficient pool cleaning. 4. The pool cleaning set is also suitable for removing dirt from the inner walls of the pool and is for cleaning swimming pools, spas, bathtubs, liner pools, water parks, aquariums, fountains, fish tanks, and more. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
