Frequently Asked Questions

What is included in the active brush holder kit?

The kit includes a bearing holder, polygon spindle, 6001 bearing, fastening screw, and spur gear — all components required for a complete replacement. Parts are not sold separately.

Which Dolphin models does Part #9991594 fit?

Why would I need to replace the brush holder assembly?

A worn or damaged brush holder causes the brush to wobble, drag, or stop rotating, reducing wall-climbing ability and cleaning coverage. Replacing the full assembly restores proper brush operation.

Is this a genuine Maytronics part?

Yes, this is a genuine Maytronics spare part (Part #9991594), not an aftermarket replacement.
