Rainbow Power nozzles

Howdy all, I am curious to know which PN you have found to be best for vacuuming your carpet. I seem to remember something written, perhaps here, that Rainbow had changed PN's.

I have a R-4573C one earlier for my D4 and another newer PN2

Please let me know.

Rainbow PN, or just PNs in general.
