Abstract
Soils and bacteria are removed from a hard floor surface by providing two resiliently flexible, transversely parallel strips, applying suction to the space between the strips so that their lower edge portions engage the floor surface, bodily displacing the strips longitudinally back and forth, while applying disinfectant or cleaning liquid to the floor surface outside the space between the strips to wet that surface over which the strips are displaced and flex back and forth.
