Abstract: A mobile cleaner includes a dust housing, an agitator, and a dustpan. The dust housing has a collection opening facing a surface. The agitator is rotatably disposed within the dust housing and is exposed to the surface through the collection opening. The agitator is configured to move foreign material from the floor into the dust housing. The dustpan directs the foreign material moved by the agitator into the dust housing. The dustpan extends around a portion of an outer circumferential surface of the agitator and is configured to rotate independent of the agitator.
