Environmentally it makes great sense. I can think of multiple uses!

I repeat that I tried THREE units and none of them worked.

Nothing...it never worked.

When something doesn't work right off, that's a red flag as to the quality.

Cleans very well without chemicals.

Sometimes needs extra pumping to get steam up. Won't sit or stand.

Environmentally safe, easy to use, does what it says

Care needs to be taken, as the water and steam is very hot.
