Central vac recommendation
House is going to be 5300 sq feet when finished. I have decided on Electrolux and keep on bouncing back and forth between the PU3650 which has 600 AW and is rated for up to 8000 sq ft and the PU3900c which has 640 AW and is supposedly good up to 12000 sq ft. Want to make sure that the thing really sucks throughout the entire floorplan but am not sure it is worth the price delta for what might be an overkill. Any advice, not just on these units, but on the power needed to vacuum a house of that size? I don't know how much stock to put in the manufacturer sq ft ratings. Links to units are below.
