I think you should procure a 1981 to 1995 Royal Heavy Duty Commercial upright with at least a 4.5 amp motor but no higher than a 7.0 amp motor, the highest rating available of the non-drop-in motor.
Models with 4.5 amp motor:
Model 607 (1985-1987)
Model 608 (1981-1985)
Model 611 (1981-1985)
Models with 5.0 amp motor:
Model 654 (1987-1990)
Models with 5.4 amp motor:
Model 608 (1985-1987)
Model 611 (1985-1987)
Model 618/620 (1984-1985)
Model 655/656, 7500/7510 (1990-1995)
Models with 6.0 amp motor:
Model 360 (1987-1995)
Model 361 (1989-1995)
Model 380 (1987-1995)
Model 381 (1989-1995)
Model 618/620 (1985-1987)
Model 660/662, 7600/7620 (1987-1990)
Model 661/663, 7610/7630 (1989-1990)
Model 680/682, 7800/7820 (1987-1990)
Model 681/683, 7810/7830 (1989-1990)
Models with 7.0 amp (non-drop-in) motor (all produced from 1990-1995):
Model 670/672, 7700/7720
Model 671/673, 7710/7730
Model 690/692, 7900/7920
Model 691/693, 7910/7930
The best brush roll to use on models with a 5.4 or lower amperage motor is part #2-080221-000. For 6.0 and 7.0 amp models, use part #2-088221-000 (for 14" wide nozzle models) or part #2-061821-000 (for 18" wide nozzle models).
