Wiper device for floor cleaning machine

摘要

The machine comprises a long wiper body with front and rear flexible blades which are arranged spaced parallel across the body. A fan creates suction in an area between the two flexible blades so that a dirty liquid, from the flexible blades, can be collected after that portion of floor has been washed. The floor contact surface of the flexible front blades is jagged and has an essentially triangular configuration. The blades may be made from rubber.
