Wet Surface Treating Device and Element Therefor Abstract of the Disclosure A rotabable element and a surface treating device including the same are provided. The rotatable element is capable of being mounted on the end of the output shaft of a conventional surface treating device, such as an orbiting disc sander, an orbital sander, a polisher (e.g., hand-held or floor polisher), floor buffer or scrubber etc., to provide a device modified according to the invention. The element comprises a first surface including a shaft mounting means for rotation of the element about an axis generally transverse to the first surface and an opposite second surface comprising or being capable of including a surface treating means. The first surface also includes a basin-like recess having a bottom surface which is generally transverse to the axis and substantially free of radial undulations and the first surface also includes sidewalls defining a channel opening toward and extending around the axis. The opposite second surface also includes an opening within or adjacent an area generally centered with respect to the axis. The element includes at least one passage therethrough communicating between the channel and the opening in the second surface so that liquid collected in the recess will flow to the channel, through the passage and out of the opening when the element is stationary or rotated about the axis.
