The WeedRoller prevents unwanted weeds and debris for a clean, safe, and sandy lake bottom. It helps eliminate unsightly weeds from reoccurring. The WeedRoller is environmentally friendly and does not require any chemicals to be used; therefore, it is safe around children and pets. It can be placed on the pier itself, or at the shore line. The rollers come in a set of three 7’ tubes that make the installation process a breeze. The WeedRoller moves in a slow rotation (5mph) that can pivot more than 270 degrees (with deep water extension tubes). If the WeedRoller is obstructed it will go in reverse subsequently, after six reversals it will automatically shut off.
