Abstract
Agitating apparatus for a surface treating appliance includes a rotatable body having at least one substantially continuous row of bristles extending outwardly therefrom, the bristles having a surface resistivity in the range from 1×10−5 to 1×1012 Ω/sq so that static electricity residing on a floor surface to be cleaned is discharged upon contact with the bristles.
