Abstract
A self-propelled sweeping machine has a sweepings pick-up device and a sweepings collection container. The pick-up device has a pick-up head and a conveying section adjoining the head having an ejection and distribution device opening into an interior of the collection container. Sweepings picked up from the traffic surface by the pick-up device can be distributed by the ejection and distribution device, with the formation of a sweepings surface, in the interior of the collection container. Also provided is a filling level sensor, which is configured as a radar sensor and scans the interior of the sweepings collection container, and an evaluation unit which interacts with the filling level sensor. A distance measured between the filling level sensor and the sweepings surface allows for the degree of filling of the sweepings collection container to be determined in the evaluation unit and to be output on a display or signal unit.
