Doesn't do much

Used this on exterior sun room windows. Overall, the windows still look dirty with water spots. The rinse and clean settings seem to both spray the cleaning agent, so I had to keep turning off the hose and putting on a regular spray nozzle to rinse the product off. Like most of these hose end sprayer products, they don't seem to really do much but spray a bunch of suds on stuff without rinsing the dirt off. The only real way to clean would to hand scrub, which defeats the point of the product.
