Dingbatt: If you have a sprung wooden floor just be aware that front loaders can shake the crap out of your house. Concrete slab, no problem.
We don’t have a sprung floor, but I can validate the shake factor esp. with towels in the machine. We have timber floors and on anything >800rpm you can really feel it.
Then again, 800rpm is pretty decent at rinse, and our f&p’s have been real troopers.
