Please follow these steps:
To remove brushes, disconnect cleaner from electrical outlet.
To prevent possible leaking, remove clean water tank and recovery tank. Set tanks aside.
Grab brush assembly and pull firmly.
To replace brushes align posts on both ends of brush assembly with slots (B) in cleaner housing.
Make sure that the square post also aligns with the square hole (D). Turn brushes slightly until post fits easily into hole.
Press brush assembly firmly to snap into place.
