Back to the moving question – we JUST did this and had to move our main floor laundry (into our kitchen/dining area of all places) so we could lay tile. To move them out, I had to cross a plywood subfloor because I had stripped off the linoleum that was there and then on to the hardwood kitchen floor. To cross the subfloor we used the hard plastic furniture moving pads, once we got to the hardwood, we switched to the felt pads – probably a 4″ diameter by 1/2″ thick felt disc. In both cases, I could’ve pushed each machine with one hand. But easier to have two people to steer around corners. Also helps to keep a little downward pressure on the machines because the discs will slip out every now an then – usually on the side you’re pushing from. No big deal, easy to slip them back under. Just buy a pack of both hard plastic and felt pads, they’re cheap and can be used to move anything heavy.
