Maytronics Grey Dolphin Active Brush Assembly, S300

The Maytronics 9995543-ASSY is the grey active brush assembly for the Dolphin S300. It is the genuine Maytronics part.

Fit

Beyond the S300, the same assembly is used on the Triton PS and Triton PS Plus, the Dolphin Active 20 and Active 30i, the Proteus DX4 and DX5i, the Mercury, the T35, T45 and T55i, and the Pentair Prowler 920 and 930.

When to replace it

Brushes wear down and lose their scrubbing action, and a worn brush also affects how the cleaner grips walls. If the bristles are short, split or missing, or the cleaner has started slipping, a new brush assembly puts the performance back.
