Well a Bosch will probably not do well on a second floor installation, Bosch has a pretty basic suspension system, at least the nexxt series did, I believe the vision series is just a prettied up nexxt. We got rid of our 500 nexxt series due to severe vibration and walking and this was in a concrete basement, we tried everything to fix this issue for 2 years, and finally just bought the LG Waveforce. No more vibration and walking issues. Since you want a water protection pan and stop leak system I believe the Bosch is the only one to have this. They do make catch pans that go under washing machines and since you already have a water and drain hookup there maybe a plumber can help you come up with a solution here. If you are installing on a 2nd floor I would get a machine that has an active anti vibration system like Samsungs VRT or LG's Anti Vibration Technology. Other brands may have there own methods as well. Hope this helps.
