Abstract
A cleaning system for pavement joints controlled and driven by a motor. A wheeled housing carries a nozzle system where a stream of pressurized or forced air is directed through rotating nozzles to clean the joint surfaces. The rotational speed (RPM) of the motor is selectively controlled by actuation of a valve by the operator, and allows the operator to selectively control the rate of rotation of the nozzles are required by the state of the surface to be cleaned. A suction head is further movable over the joint surfaces to remove the debris dislodged by the nozzle system and airflow.
