Great cleaning helper: The bristles are stiff enough to clean thoroughly, but not so stiff that they scratch the surface. The round design makes it easy to reach tight corners and scrape away dirt with a simple twisting motion. Flexible use: You can use it separately for easily accessible areas, or attach it to the telescopic pole to easily reach hard-to-reach corners and crevices, meeting your requirements in various conditions. Excellent quality: Our pool cleaner is made of a hard plastic handle that provides sufficient strength to control the brush, with thick bristles and each bristle tuft is evenly clamped onto the brush to prevent the bristles from falling off. 2 pieces in 1 pack: The package contains 2 pool corner brushes with sufficient quantity, which can be good tools for cleaning pools, spas, hot tubs, and ponds at any time and easily replacing them. Easy to install: Our pool corner brush can be mounted on telescopic poles with a diameter of 1.2 \" to 1.3 \", simply insert the pointed bottom of the brush into the pole with adjustable clips to fix the position on both sides for use. Specification: Material: Plastic Brush head diameter: 3.9 inches
