ABSTRACT:
A machine for scrubbing floors has a frame with an open bottom from which a lower run of an endless fabric belt projects downwardly, this belt passing around a large traction roller and several idler rollers journaled in the frame. One of the idler rollers is spring-loaded and mounted in a receptacle for water or other liquid into which the upper run of the belt dips from above before passing through a wringer constituted by a further roller and a coacting pressure roller. The traction roller is hollow and driven by a motor supported in its interior by an axle traversing one of the end faces of that roller.
