Product details
Polaris R0518700 is the genuine brush separator for the 9300, 9300xi and 9400 robotic pool cleaners. It is a small part with a specific job: holding the brushes in the right position on the roller.
What goes wrong
Separators live in the same abrasive environment as the brushes, taking grit, chlorine and constant flexing. When one cracks or wears through, the brush it holds can shift along the roller or work loose, and the cleaner leaves streaks and missed patches behind. Owners usually blame the brushes first, when the separator is what let go.
Fitting
Count the separators on your roller before ordering, since this listing is a single part and the number used varies with the brush arrangement. If the brushes are already worn enough to need changing, fit fresh separators at the same time so the new brush set sits correctly from the start.
