HydraMaster

This attachment allows the RX-20 to quickly convert so it drives either carpet cleaning bonnets or standard hard floor pads. The 15-inch drive block accommodates a 17-inch carpet bonnet.

This felt ring is for the hub on the RX-20 star assembly (head). It provides a buffer between the plastic hub and the the shroud that, when oiled, will prevent the head from seizing to the shroud.
