This is an efficient tool for vacuuming gravel on a flat surface. This suction mouth is mainly used for vacuuming gravel on roofs. The method of use is comparable to that of a hand truck. When the vacuum hose is connected to the back of the suction mouth, there will be a vacuum on the suction mouth. Then all the gravel that is in front of the mouth is sucked up and discharged through the hose.
