The invention is a new floor-cleaning machine, with brushes and motor mounted on a support which travels sidewards; the motor is positioned on the side opposite to the travelling direction of the support, in such a way as to allow the brush to protrude. The support can also rotate on the vertical axis so as to move the two brushes from the position in which they are aligned to the position in which they are side by side. The brushes can be provided with traditional discs or with a dragging disc equipped with two concentric elements made of rubber with different densities, owing to which the dragging disc edges maintain their correct shape over time.
