Device realized as scrubber-dryer machine for cleaning walkable surfaces, as for example floors, pavements, asphalted roads, etc. for cleaning walkable surfaces, adapted to move forward automatically and to be steered manually by an operator, and constituted by a cleaning lower base body connected on its upper part by means of a movable jointing element to a steering means lengthened upward, said lower base body comprising a frame to which one or more lower brushing means (21, 22) are fixed to and actuated in rotation by means of respective electrical actuating means (27, 28), and adapted to brush the walkable surfaces, by removing the dirty from it and to create a friction with the walkable surface such to move forward automatically in a rectilinear way the device, at least a wetting system fixed to the frame, and positioned in correspondence of said brushing means (21, 22) and adapted to wet them, and at least a dirty collection system fixed to the frame, positioned on the back of said brushing means (21, 22) with respect the travel direction of the device and adapted to collecting the dirty brushed by the same brushing means, said wetting system being constituted by one containment means, adapted to contain the cleaning liquid, one electrical pumping means, adapted to draw the cleaning liquid, and delivery means for delivering such a liquid, said dirty collection system being constituted by at least one restraining means, adapted to restrain the dirty conveyed by the brushing means (21, 22), at least one suction means, adapted to suck the restrained dirty, and at least a collection means, adapted to contain the sucked dirty, said steering means comprising an upward lengthened body joined at the top thereof to a handle, and being of the inclinable type in any direction from a starting position perpendicular with respect to the lower body and being adapted to steer the device, characterized in that said jointing element is constituted by a lengthened elastic and internally hollow push element, constrained with its lower end portion to the frame, in the barycenter point of the lower body and with its upper end portion to the steering means, and that from the rest position thereof, in which it has a rectilinear upward extension, it may be curved downward by applying a downward and outward push force to the upper end portion thereof and in any direction with respect to its vertical axis when it is in the rest position thereof, therefore to incline downward the steering means, and in this curved position being able to rotate along the vertical axis of the rest position of the same elastic element, without that the lower body be interested by such a rotation, by decreasing the downward push force of the upper end portion, the elastic element returning automatically toward the rest position thereof, such an elastic element being also adapted to receive a twisting moment to its upper end portion, by means of said steering means, for then applying said twisting moment, with its lower end portion, to the frame of the lower body, therefore this latter rotates on its perpendicular axis extent upward of the angle desired by the operator, without be inclined.
