Abstract
A cleaning machine for cleaning a surface is provided. The cleaning machine includes a base assembly that moves along the surface and a liquid distribution system associated with the base assembly for distributing the cleaning solution to the cleaning surface. A suction nozzle assembly is mounted to the base assembly and includes a front nozzle portion and a rear nozzle portion. The front nozzle portion defines a fluid flow path having an inlet opening and an outlet opening and the rear nozzle portion defines a fluid flow path having an inlet opening and an outlet opening. A suction source is in fluid communication with the suction nozzle for applying suction to draw the cleaning solution and dirt from the surface and through the suction nozzle assembly. The fluid flow path of the front nozzle portion is closed in response to the base assembly moving in one of the forward direction and rear direction. The fluid flow path of the rear nozzle portion is closed in response to the base assembly moving in other one of the forward and rear direction.
