The 16" Curved Wall Brush removes algae and grime from the sides and floor of the pool. This curved brush is optimal for pool cleaning. It's compatible with a 1-3/16" inner diameter telescoping aluminum pole. The Intex 110" Telescope Aluminum Shaft Pole (not included) fits perfectly with the 16" Curved Wall Brush. This same pole can also be found in the Intex Deluxe Swimming Pool Maintenance Kit. You can upgrade to this maintenance kit for a superior cleaning experience if your pool is 1' or larger.
