A floor sanding machine (1) has a frame (1) which carries on its underside a motor-driven, vertically adjustable sanding plate (4) with a sanding disk, an annular dust suction nozzle (11) which surrounds the sanding plate, and two front running wheels (13) and a rear wheel (14) which support the frame. A controller (7) analyzes the signals from a laser scanner (18) for measuring the distance from the sides and front of the sanding machine to the wall and controls by means of a servo system (17) the rear wheel designed as a tail wheel and a rear wheel driving motor (16) for moving the sanding machine. The pressure applied by the sanding plate, the sanding plate driving motor (9) and a sanding dust suction turbine are also controllable by the controller. The sanding dust suction turbine is arranged outside the surface to be sanded, and the dust suction nozzle of the sanding machine is connected by a suspended suction line (12) to a dust bag of the suction turbine.
