ABSTRACT:
A surface cleaning system which allows a sponge or other cleaning element to receive cleaning fluid transported by conduit from a pressurized cleaning fluid container and to apply the same to a surface to be cleaned. A vacuum source extracts the used cleaning fluid from the surface as the operator moves the cleaning element back and forth over the surface to be cleaned to remove the cleaning fluid and contaminants therefrom. The used cleaning fluid then travels by a conduit to a separation container where it is filtered and collected. The used cleaning fluid or fresh fluid can be pumped by a sump pump to a flush basin for rinsing or cleaning the cleaning element. The sump pump is controlled by a pressure valve located in the base of the flush basin. The complete system is typically operated on 115VAC and is portable by way of a push cart.
