This is an efficient tool for vacuuming materials, particularly roof gravel, from flat surfaces when used in combination with an suction excavator or vacuum machine.
The suction hose can be connected to the rear of the suction head, allowing the vacuum generated by the machine to collect materials directly in front of the suction head. In operation, this specially designed suction head works in a similar way to a hand truck.
The materials are drawn through the hose and collected in the container or tank of the vacuum excavator or vacuum unit.
