I have an interesting mental image, Stilly, of your washing machine waltzing *very* *very* *slowly* about the room, pushing a tide of new flooring tiles in front of it. This calls for a time-lapse movie :-) ?

Hopefully your washing machine won't emulate the mainframe disc drive (about the size of a washing machine, and of course always on Spin), which, according to legend, moved across the server-room floor, and blocked the only entrance to the room [see "walking drives" in the Jargon File].
