Vacuum Cleaners Discussions

Carmine and I suggested a new thread.

Let's hear all there is about Filter Queens.  All I basically know is they are exclusively appointment only DTD.  They are expensive, and they last for freeking ever.  I have heard they have gone plastic, but other than that the basic design hasn't changed. 

Did Royal once build them?  Or did they build Royal?

The reason F/Q did not put in bigger motors is: a more powerful motor tips the airflow/suction ratio toward suction, meaning more of the fine dust clings to the filter, causing it to run hotter. It IS possible to clog a F/Q w/ drywall, plaster, concrete, or road dust. Seen it happen,.Sold model 31X in undergrad years. Those were really, really good vacuums, even on carpet w/ straight airflow nozzles
