ABSTRACT:
This invention is directed to a free-floating-brush assembly for use in combination with scrubbing and polishing machines employed for cleaning and buffing hard-surface floors in large areas such as found in supermarkets, schools, hospitals, etc. The assembly includes a housing having a pair of floor brushes mounted therein and driven individually by battery-powered magnetic motors. The assembly is freely suspended in front of the machine by means of a joystick mechanism which allows for raising or lowering the housing assembly. A swivel device having a connecting pin is mounted and is pivotally connected to a crank arm member which forms part of the joystick mechanism. The assembly is angularly disposed and held in place by a pair of spaced spring members that further allow the housing assembly to not only rotate about the swivel device, but to freely adjust to any uneven floor surface.
