I have and installed central vac systems for years. My parents had one installed when I was a kid, I am 61 now. It is still being used. All that was needed is a new hose every few years (ten or more). As far as installing a new system, there is many to choose from and many different attachments that can be purchase. In my current house, I have a system even though I do not have any carpet. I have a hardwood floor head I use with the floors I have. I installed a large unit and so I do not need to empty the container but about twice a year if that often. The best part about a central vac system is that it exhaust outside so it does not stir the dust up inside.
