A:Answer It can be used on everything, long as you just use water, I haven't tried using all chemicals yet, but I live in a Apt and it's prefect for the balcony, tried it in the shower for the heck of it and found out you'll still have to scrub, it's great for rinsing the shower, plus you can use the toleit tank.
I'm limited in what I can do, but if I had my own place, I'd be using this all the time. Water pressure is regulated by the noszel so you can adjust pressure, don't know how long the battery lasts though, but I got a small place, so it's cool.
Also, it's kinda quiet too.
