ABSTRACT:
A rotary flooring cleaner-polisher wherein a shroud overlies a plurality of floor contacting rotating wands. The operator is able to selectively supply fluid, a vacuum or both to the area beneath the shroud permitting both application and extraction within the defined area via a hollow central drive shaft. At least one of the rotating wands which are flexibly mounted to the drive shaft includes an elongated slot along its lower surface in communication with the vacuum source such that the extaction is done through the wand and then through the drive shaft. The solution to be applied to the flooring surface may be sprayed in a general pattern beneath the shroud or in a controlled manner through the interior of one or more of the wands.
