The difference
is...the hospital models filter box is squared and it’s a G which has the big switch on the top up high just past the handle. Smaller details on the hospital model that are different are larger front wheels, all wheels were equipped with chrome “hubcaps”, automatic control dial on the front bag door, which I think is polished aluminum and full length teal colored side bumpers. But yes, if you don’t look carefully the white L’s especially the ones with the cordwinders could quickly be mistaken for the hospital G’s since the basic main body and coloring scheme are the same. Of course the hospital G has a cordwinder too, but since it was standard equipment for the G it is an integrated design forming the back end of main unit whereas the cordwinders for the L were designed as a “plug and play” design that was quickly added by removing the cord halo with two screws, unplugging the plug in power cord, and the plugging in the cordwinders pigtail, and putting the cordwinder in place of the halo using the same two screws.
In fact, when I’ve had AF’s R’s or L’s with this cordwinder, if the motor goes bad, the cordwinder is easily swapped onto another of these machines that doesn’t have one. Though the cordwinder does tend to weigh the machine down quite a bit. I don’t know if the filter box for the hospital G is easily removable or not and could be put on another machine. That would be something to look at if I ever get my hands on a hospital G.
