ABSTRACT:
A rotary clutch shaft of a floor machine removeably receives and rotates a brush block having downwardly protruding circumferentially arranged brushes protruding from the periphery of the brush block. Hooks which protrude from the bottom of the block, removeably retains a reversible, tufted, resilient, absorbent bonnet confined within the brushes and a frictional drive on the brush block engages the upper surface of the bonnet and rotates the bonnet as the block is rotated. The bonnet is readily removeable and can be laundered and reinstalled.
