DEFINITION

Classification: 15/363

(under subclass 300) Cleaning apparatus of the kind adapted to be moved about over the surface being cleaned having, in addition to air draft applying means, means for brushing, beating, shaking, or otherwise contacting and agitating the work to dislodge and/or remove unwanted foreign material.

(1) Note. Since nozzle lips usually have a floor covering pile agitating or deflecting action, the mere recitation of such is not considered to be significant agitator structure; but where the nozzle lips are modified to enhance their action as an agitator, classification will be in this or the indented subclasses.
