How To Replace the Maytronics Dolphin Nautilus Combined Brushes

If your Maytronics Dolphin Nautilus Robotic Cleaner is not picking up the dirt and debris as effectively as it used to, it may be time to replace the Cleaner's Brushes. This cleaner has the option of using a Combined Brush with Climbing Rings incorporated into the ends of the brush to help climb the wall. If your Cleaner is not climbing the walls, it may be time to replace these rings with the brushes. This guide shows you how to replace the Nautilus Brushes and Climbing Rings.
