ABSTRACT:
A floor sanding or polishing device includes a housing that can be guided across a floor. The housing carries a motor which rotates a plate in a first direction about a vertical axis. The plate carries a plurality of sanding or polishing discs that are rotatable in the same second directions which are opposite to the first direction of rotation of the plate. The discs are displaceable radially relative to the plate by centrifugal force to bring a gear of the disc into engagement with a ring gear affixed to the housing, whereby the discs are rotated about their respective axes in response to rotation of the plate.
