Please explain the difference, if any, of the green-, white-, and blue-bristled brush rolls formerly available through Electrolux/Aerus. And, by the way, what does "HPO" stand for?
What I've observed or read already:
1) The Model U140A/Lux 4000 and Models C134D, C134E, and C134F (not sure about all of them)/Lux 9000 had pns with special motors that could better handle the green-bristled HPO brush rolls. The pn Model N142A seems to be the only one that was factory-equipped with the HPO brush roll.
2) The Model D146A/Drilux (dry carpet cleaning system) came with the multii-helix white-bristled brush roll (looks like a TriStar "T-shape" rebadge).
3) The Model D146B and D146C DriClean/Driluxes (standard L-shape nozzle) came with the blue-bristled "pile lifter" brush roll and were sold around the time of the 80th anniversary Model C152E/Ultralux.
4) The green-bristled brushes were stiffer than the standard black-bristled double helix rolls.
Is this information accurate?
Did the Centralux power nozzle(s) and/or commercial cleaner(s) that were available from branches at the time come equipped with the HPO brush rolls?
