A BIG assed Shopvac fitted with a Hepa filter and an old ElectroLux powerhead
and wand attached to 24 feet of this.

It will suck the paint off the walls.

Good idea .... very close to a central
system ... except that most central units
exit the gray air outside the house.
One thing you have to watch, many
shop vacs are designed for more volume
and somewhat less pressure. Typical
central vac have sealed suctions of 90
to 120 inches of water. I had a Sears
canister that advertised a sealed
suction of 90 inches of water. Shop
vacs might
only be 50 inches or so. While sealed
suction isn't purely releated to
cleaning power,
volume and working suction together is
important. How to measure this is open to
much discussion. Central systems do
need higher suction due to long lines
from the
unit to each room's inlet. BTW, I was
thinking of using a shop vac as a
"central system"
in a motorhome. Motorhome central vacs
are way, way overpriced, typically in the
$300-400 range .... almost like a home
system, but a lot less vacuum.
