Has anyone used this product? I was thinking about getting one, it looks like it's easier than a mop.

I'm interested to know as well.
My whole house is porcelain floor.

I don't know about the hoover machine, but I have a thing like this

works way better than a mop since the floor is dry afterwards. I have ceramic tiles everywhere. I sweep the major debris first and then just wipe with a similar sqweegee thing. It does clean off bird poop.
Sometimes I use tile cleaner or lemon in the water to give a fresh smell.
