Polti Vaporetto 3 Clean ( 3in1 Vacuum Steam mop and Steam cleaner)

Manual is not so clear with it's instructions. I find it a bit annoying that I need to press the steam button in order for it to generate steam. so the whole time I'm mopping the floor, I'm holding the steam button. Nevertheless, it made my cleaning faster. Vacuum and steam at the same time. I just wish there is a way to make the steam continuous with one button click. also, pls. improve on the packaging/shipping. we got the box with a hole. screws scattered inside the box.
