Central

When I was a teenager my family moved to Idaho. One of the things us kids thought was cool in our new house was the central vacuum. Each room had a port to hook up the long hose, and we had fun opening the ports because the suction would start up right away. The central vacuum motor and dirt bin thing were located in the garage. The only problem we had was that it would often get clogged, and with the hose running behind walls in the whole house it was hard to fix a clog. Eventually we just stopped using it at all, but it was pretty cool while it lasted.
