Surely not the right hose.
I have one of these burried in storage. Mine is a straight suction ( no outlet for a power head). I used mine for a bench vac for a while. Sadly filter queen no longer makes any parts in the salmon color. Everything is black now, though you may be able to find chocolate brown still. Their are also aftermarket hoses in chocolate brown available, don't waste your money. They don't fit correctly on either end. Do you have all the attachments? As far as filters go, I only use the genuine filter queen cones. Iv tried all the aftermarket ones and haven't been satisfies with any. The originals just perform better. You have a nice machine. Those older ones all use Ametek motors. Those motors last for ages an pull more air than the new style motors.
