Last week all the tubing for our central vac was installed. We’ve got 10 plug-in points around the house, and will have three 30 to 50 foot hoses. The new generation of central vacuum systems have hoses that have the wire integrated (so that it doesn’t get caught on things as you drag it around) and the hoses are much lighter than past systems.
We were a bit torn about the expense, so we asked around. It seems that people who have a central vacuum system installed rarely regret it.
