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 an insert having passages therein for providing a desired product dilution 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 the insert 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.

[ What is claimed is:] [1.] 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 mixing chamber being located in an insert supported in a recess in the housing;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; andthe valve member being operable to selectively feed the diluted product to the second outlet or feed rinsing water to the first outlet.
