A portable cleaning apparatus for cleaning a surface is provided and includes a housing. A distributor is operatively connected to the housing for distributing solution to the surface. A first solution container is mounted to the housing and contains a first solution. The first solution container has a bottom portion with an outlet portion fluidly connected to the distributor for supplying a flow of a first solution to the distributor. A second solution container with an outlet is provided in the first solution container and contains a second solution. The outlet of the second solution container is fluidly connected to the distributor for supplying a flow of a second solution to the distributor. In at least one aspect of the invention, the second solution container is design and constructed to transfer the weight of the first solution above the second solution container to the second solution in the second solution container to produce substantially the same hydrostatic head at both the outlet of the first solution container and the outlet of the second solution container.
