Royal/Dirt Devil Cruiser Self-Propelled Brush Roll 091700 091750 31150 when the self-clean cycle runsThis replacement brush roll fits the Royal Dirt Devil Cruiser Self Propelled upright vacuum, serving models 091700 and 091750. The agitator drives the carpet cleaning action: its spiral bristle rows loosen ground in grit and lift it into the airflow as you guide the self propelled cleaner across the room. A brush roll that has lost its bristles or seized at the bearings will leave streaks of uncleaned carpet and put extra strain on the drive belt.
