The roller brush is a core interchangeable cleaning attachment specially matched for water fed pole systems. Built with dense soft synthetic bristles wrapped around a rotating roller frame, it features a built-in water outlet design. Running purified water evenly flows through the brush surface while rolling back and forth, which scrubs stubborn dirt, pollen, algae, bird droppings and grime thoroughly from glass, sunroom panels and exterior facades. Its round rolling structure fits curved and sloped surfaces perfectly, delivers more uniform cleaning than regular flat brushes, and prevents scratches on delicate glass and polycarbonate materials. Easy to mount, replace and connect with all standard telescopic water fed poles.
