Sprayer for cleaning exterior surfaces
A sprayer is disclosed that may be attached to a garden hose for cleaning exterior surfaces such as windows. By turning a flow selector in a single direction tap water from the hose first flows through the sprayer to rinse the surface to be cleaned. The flow selector can then be set to spray a mixture of cleaner (e.g., one or more surfactants) and surface modifier (e.g., one or more polymers) and water on the surface. The flow selector can then be set to an off position to allow for scrubbing of the surface with a scrubbing tool. The flow selector can then be set to rinse the surface with untreated water, and the flow selector can be turned further to rinse the surface with filtered tap water produced by a filter in the sprayer. Also disclosed are unitary cartridges providing a combined replacement of the cleaning surfactant and a filtering system for deionizing the water.
