A double barrel sprayer for applying a diluted product such as a diluted cleaning solution to a surface for cleaning thereof and rinsing the diluted product from the surface by spraying a water-only rinse onto the surface. The sprayer can include a force-fitted orifice plate with a plurality of holes for adjusting the water/product mixing ratio. To provide different spray patterns for the water-rinse or diluted product, the sprayer can include a shroud having suitably shaped exit holes. The sprayer includes separate flow paths for the water-only rinse and the diluted product. The flow path for the diluted product includes a mixing chamber in which concentrated product is siphoned from a container and mixed with water supplied by a garden hose. Prior to mixing with the water, the concentrated product passes through an orifice plate having a plurality of holes to provide a substantially constant water/product ratio over a wide range of water pressures. The sprayer includes a removable cover which includes a pair of outlets suitably sized and shaped to obtain desirable spray patterns for the water-only rinse and the diluted product sprayed from the sprayer. A rotatable valve allows selective application of water or diluted product.

A portable sprayer for applying a diluted product to a surface to be treated, comprising: a housing having first and second inlets, first and second outlets, a mixing chamber and a valve member; the first inlet supplying water to the sprayer; the second inlet supplying a concentrated liquid product

A portable sprayer for applying a diluted product to a surface to be treated, comprising: a housing having first and second inlets, first and second outlets, a mixing chamber and a valve member; the first inlet supplying water to the sprayer; the second inlet supplying a concentrated liquid product to the sprayer; the mixing chamber being in fluid communication with the first and second inlets such that water is mixed with the concentrated liquid product to form a diluted product by feeding water through the first inlet and feeding the concentrated liquid product through the second inlet the housing including a passage in fluid communication with the first and second inlets and second outlet, the passage including an upstream portion and a downstream portion, the second inlet being fluid communication with the downstream portion, and the downstream portion having a larger cross section than the upstream portion so that concentrated liquid product is siphoned into the downstream portion and mixed with water supplied through the upstream portion to provide the diluted product, the diluted product being conveyed in the downstream portion without exposure to atmospheric air until the diluted product is sprayed through the second outlet; the first outlet spraying rinsing water from the sprayer to allow removal of diluted product from a surface to be treated; the second outlet spraying the diluted product from the sprayer onto a surface to be treated; and the valve member being operable to selectively feed the diluted product to the second outlet or feed rinsing water to the first outlet or prevent rinsing water from flowing to the first and second outlets.
