Steam cleaners for mold, floors and furniture

Hi! Im kinda sick of having several cleaning agents for cleaning floors, the toilet, bathroom and most of all the mold on my bedroom walls. So i've been thinking about a steam cleaner. I've read that you need at least a 4 bar steam cleaner to kill mold. And to clean your matrass (cus im sacred mold also got into it) you need to be able to control the amount of steam that comes out of it. Since to much moisture will make it too wet, resulting in more mold hehe.

I really wanna safe money and the environment in the long run with this purchase. Since buying all those cleaning products cant be great. But waste from electronics isn't great either ahah. Hopefully you guys can share some recommendations or experiences with steam cleaners! Thanks a lot!
