scooter

A wastewater collection system cleaning tool whose cleansing action depends on the development of high water velocity around the outside edge of a circular shield. The metal shield is rimmed with a rubber coating and is attached to a framework on wheels (like a child’s scooter). The angle of the shield is controlled by a chain-spring system that regulates the head of water behind the scooter and thus the cleansing velocity of the water flowing around the shield.
