Upgrade your Dolphin Sigma with the genuine Maytronics Center Active Brush Assembly, designed to provide more aggressive scrubbing and improved cleaning performance on pool floors, walls, and the waterline.
The active center brush rotates at a higher speed than the robot's drive system, helping loosen stubborn dirt, algae, biofilm, and fine debris before it is vacuumed into the filter basket. This results in a deeper clean, especially on slippery surfaces and areas where debris tends to stick.
This is a genuine Maytronics replacement part and is only compatible with select Mid-2026 Dolphin Sigma models that were manufactured with the updated center brush system.
