My Dolphin 4 has foam rings in the brushes and they have become brittle and cracked. Our local pool store cannot find them on any parts list and the new models do not have them. Can you point me towards a source, or should I just leave them off?
ADMIN REPLY: I believe you are referring to the climbing rings. Here is a link to where they may be purchased, cut and paste into browser window. http://www.aquaqualitypools.com/parts_list_maytronics_dolphin_dx4.htm
