Does the brush use a seperate motor?

The power head isn't lacking. The head is lacking power. It is working as designed, it just isn't powerful enough. Yes, it has a separate electric motor, for use on carpet only. Works OK in the garage, reasonable suction, without any tubing runs. IMO, it can't cope with the pressure drops induced by the whole-home installation. It also sounds like a 737 on takeoff, so you can't work in the garage when it is running.
I think I have a project here, I could build a simple manometer and see what sort of power it has at each wall outlet on each level of the house.
