I have had several in different houses over the years. The first one was a Vacuflow and it had the cyclonic filtration, so no filters to mess with. I had it installed and when I was transferred, took the power head, hoses and all the tools with me. I bought the pipe and fittings and installed it myself. Easy, with a few good bits and extensions. We also wired an electrical outlet beside each vacuum outlet to plug in the powered hose on the beater bar. Outside exhaust is a must and the house stays much cleaner, lots of suction and way better than a drag around. I had outlets in the garage but used my shop vac for those jobs and stuff like drywall which will kill most vacuums. In the 4 moves since, I have installed built ins and left them when we transferred. All were installed by me and once you figure out the basic rules for the piping, get the right sized unit for your application and quality hose and tools, you will never go back. The German made hoses and tools are by far the best. I buy Canavac powerheads on this side of the border but you will have comparables in the US.
