The Blue Diamond R/C is the ultimate pool cleaner. It works in any pool. PVA brushes provide unmatched traction and climbing ability. Removes algae, bacteria, pollen, dirt, sand, silt, acorns, twigs, staining metallic particles, small and large leaves, etc...it even scrubs the waterline. The Radio Remote Controlled model allows quick "spot clean-ups" or to guide the Blue Diamond to areas of the pool that may require extra cleaning attention.
