ABSTRACT:
A manually-operated floor polishing machine comprising a polishing pad or brush rotatable at a speed above 660 rpm, pressing against the floor with a force of less than about 25 lbs., and positioned so that one segment of the pad presses harder against the floor than the other, such as by mounting the pad's driving plate or disc so that its plane of rotation is at an angle less than about 10.degree. to the plane of the floor. The rotating polishing pad is mounted under the driving plate which plate is driven by an electric motor. The driving plate and motor are mounted on a frame, which frame is supported by a pair of parallel wheels located so that most of the weight of the machine is supported by these wheels. This whole assembly is guided by a rearwardly extending handle attached to this frame.
