Abstract
A rotary scrubber-polisher base has a pair of vacuum liquid pickup attachment supporting mounts mounted from opposite side portions of the base and including laterally outwardly projecting mounting shanks for support of opposite side portions of the attachment therefrom. During periods of non-use of the attachment the latter is removed, but the mounting shanks therefor project outwardly from opposite sides of the scrubber-polisher base and thus prevent those opposite sides from moving into close proximity relative to stationary objects. The mounts are supported from the base in a manner such that they may be readily angularly displaced approximately 90.degree. relative to the base to thereby swing the mounting shanks fully inwardly of the opposite side peripheral portions of the base from which the mounts are supported.
