Central Vacuum System – The central vacuum system was reportedly designed and installed by Orville himself. It is said that Carrie Grumbach, his housekeeper, disliked the system and refused to use it; in fact, Orville is reportedly the only person to use the system. The system was installed in the baseboards and floors throughout the house, and some outlets can still be found.
