I've got loaded, I put the recommended water level (manual in German and English but it is not complicated to understand) the black button on the inside of the handle to turn the unit on, the trigger on top to spray water or detergent. This device is great for regular maintenance, when windows are very dirty or oily it is better polish up the front or make several passes with the device. On dusty windows, I sprayed hot water, 2 shots squeegees Mr Sunny windows are clean, as with all the flights we can find water features, dry cloth shot and the result is flawless ! I found cleaning my windows was quick and nickel, no tedious I am satisfied and I will use it often!
when removing the nozzle squeegee and that one looks up the body of the device, there is a U-shaped thick white tissues lying inside, it can be removed with 2 fingers, simply go under the water to clean it, when you clean your windows dirty water is sucked and passes through the tissue that retains the dirt. and is not found particles in the tank water. is ingenious and practical.
