The present invention creates a pair of non-variable rollers which are coupled as a male component and a female component to rotate in the facing directions and rotatably mounts the rollers on a cleaner body to come in contact with a floor by a line. The male roller in the pair comes in contact with the floor by a line to shoot the leaves on the floor to move the leaves between the rollers and forcefully send the leaves on the discharging side of the roller pair. Then, a scraper forcefully separates the leaves from the roller pair to ensure the leaves to be delivered to a collecting back without using a negative pressure source. Accordingly, the present invention can collect large sized leaves more efficiently. |
