My new washing machine spins three times faster than
my old unit. Very nice results. But, it does vibrate my
floor to a much greater extent than the old unit. My house
is ~13 years old (made in USA) and my floor is made of
plywood, ~1" thick. Has anyone ever heard of this greater
vibration damaging the floor? I plan on living in this
house for a lot of years!

Seems like I hear a news story about a washer spinning itself through the
floor and into the basement almost every day.
