There is a Brown and chrome Filter Queen vacuum shown and used with a straight suction Nozzel on
Netflix " Fringe" series, season 3 , episode 15, called "Project 13."
If any fellow Vacuumlanders have Netflix check it out.
Within the first few minutes of the episode it shows the mom vacuuming the area rug in the living room with the F/Q using the straight suction Nozzel .
She then turns it off and places the wand on top of the vac,
It sounds to me like its the real sound for the vac.
The time frame is 1985 for that episode is what they show.
