The Maytronics 6101611-R4 is a set of four replacement Wonder Brush climbing rings (also known as “climbing snails”) designed for robotic pool cleaners equipped with PVC or foam brushes. These high-traction rings provide the necessary grip for the robot to navigate 90-degree transitions and vertical walls, especially in fiberglass, tile, or vinyl liner pools. These rings are manufactured from a specialized PVA-style foam that expands when wet to ensure maximum surface contact and drive-system efficiency.
