Cleaning machine for cleaning a surface
First Claim
1. A cleaning machine configured to clean dirt, the cleaning machine comprising:
- a base assembly;
a liquid distribution system configured to distribute cleaning solution;
a suction nozzle assembly mounted to said base assembly, said suction nozzle assembly including a front nozzle portion and a rear nozzle portion, said front nozzle portion defining a fluid flow path having an inlet opening and an outlet opening, said rear nozzle portion defining a fluid flow path having an inlet opening and an outlet opening;
a suction source in fluid communication with said suction nozzle and configured to apply suction to draw the cleaning solution and dirt through the suction nozzle assembly;
a recovery tank in fluid communication with said suction nozzle assembly, said recovery tank configured to collect the cleaning solution and dirt drawn through the suction nozzle assembly; and
a valve assembly in fluid communication with said suction nozzle assembly, wherein in response to a direction of movement of the base assembly, said valve assembly partially covers the front nozzle portion and partially covers the rear nozzle portion such that the cleaning solution and dirt is drawn through both said front nozzle portion and said rear nozzle portion.

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.
