yeah these things are common, we used to have one at my old house and it was built in the 70's. Basically you have the hose, two long steel poles, and the vacuum head, which you plug into a socket on the wall, you have multiple sockets around the house which you plug the vacuum into. All these sockets lead to a big tank outside which has the motor and the vacuum bag, which gives the power and collects all the rubbish.
Has anyone ever had any problems with their wall vacuums? Our one used to get blocked very easily.
