To replace brush heads:
Pull firmly to remove existing brush head. Align new brush with square, tapered end of turbine shaft and push FIRMLY into place.
Purchased the brush hero to make my life easier when cleaning my 3 piece mesh wheels (which has 20 spokes per wheel). I’m extremely happy with my purchase of the brush hero as it dramatically cut down on the scrubbing time and been raving to my friends to go purchase for their custom wheels! Excellent product!
Very nice product. Can’t wait to use them this spring.
