Query: Works, but our floor is ruined

This works well if you keep it in one place and don't move it. Our hardwood floors were recently refinished and we now have buckling due to this leaking and we weren't aware so it sat there a while. I am about to look for a new one and donate this one. But I wanted to make certain I forewarned others before purchasing.
