Nice collection of commercial machines. I enjoy the Windsor/Sebo machines. That VS18 is probably a bit unwieldy in your home but they make fantastic hallway vacuums.
I really like the Windsors, they're one of if not my most favorite commercial vacuums ever. On a side note, you're not supposed to hang your hoses on the Versamatic and EON like that. You should get a wand for your EON, it's not good for the airflow without it and your hose would pop out when you're using it. This is what the Versamatic is supposed to look like, the top hook if for the cord.
