ABSTRACT:
A rotary-brush device comprising a downwardly open flat housing closed at its bottom by a cover threaded into this housing and defining a chamber in which a disk having edge-fixed vanes is received. The disk is propelled by a water jet trained on the vanes from a nipple formed on the housing and directed to the flat chamber receiving the disk. The disk is connected to a hollow shaft which rides in a recess formed in the top of this housing and in a bore of the cover, a threaded lower end of the hollow shaft carrying a rotary brush. A hollow shaft has an opening communicating with the chamber. The upper wall of the housing is provided with a passage communicating with a compartment above this wall closed by a threaded cap and receiving a liquid detergent which is to be mixed with the water.
