16. A scrubber apparatus for cleaning floors, the apparatus having a base assembly disposable upon a floor and a handle assembly extending upwardly from the base assembly, comprising a releasably lockable joint assembly for connecting the handle assembly to the base assembly, the releasably lockable joint assembly comprising:
a main handle shaft;
a linking member;
a pivotal connection between the main handle shaft and the linking member;
a pivotal connection between the linking member and the base assembly; and
a locking sleeve slidably disposed around the main handle shaft and slidable axially thereon to surround the linking member and to surround the pivotal connection between the main handle shaft and the linking member, and to surround the pivotal connection between the linking member and the base assembly;
wherein the releasably lockable joint assembly is movable between a fully locked configuration when the locking sleeve surrounds the linking member and the pivotal connections, and a fully released configuration when the locking sleeve is withdrawn from surrounding the linking member and the pivotal connections so that the handle assembly is freely pivotal in relation to the base assembly; and
whereby the handle assembly may be temporarily disposed in a locked upright position in relation to the base assembly, and may be released for freely pivotal movement, in at least two degrees of freedom, in relation to the base assembly.
