Bill,
The Perfect Vacuum is made by IMIG of New York. It is assembled in China of US, Chinese, and German components. It has the newer designed Ametek advantek motor. These motors run much cooler as the brushes come right after the fan unit, instead of being at the back end near the commutator like all others.
It is like the old lux 1521 canister, without the bag full indicator. The power nozzle is very similar to the lux pn 5. They have done some mods to later model power nozzles as the motors being used are like the current lux pn motor, which the body is not as long, but the shaft is a little longer to compensate. The first version pn was noisey to say the least, kinda had a rumbling sound to it. What they have done with the later version, is right under the motor, a little plastic pole was put in to prevent the shaft end of the motor from moving around. (on the original pn 5, there were two mounting screws at the shaft end, with this newer style motor, the body is not long enough to utilize these two screw holes, as a result this end of the motor tended to bounce around, hence the pole under the motor at this end) These newer versions are a vast improvement in noise level.
Their hepa bags are excellent, I am also using them in my Lux vacs. One thing to point out with these bags, is the cardboard collar is 50% thicker to withstand the extra suction this unit has. Yes, regular lux bags will fit, but the phenomenal suction of this unit can cause the collar to split or cave in. In regards to suction, I have not seen another canister that can put out as much lift and CFM as this one. In fact, on the inches of lift gauge, and the baird airflow meter at the hose end, this vac has beet many built ins at their hose end!!
As long as the components are reliable, the metal construction should take a beating as compared to the plastic crap that is out there today.
