Need something other than the heavy-duty brush that came with your Prolux Core? Try out this medium-duty brush for less abrasive cleaning! Like other Prolux Core brushes, this works great on all hard-floor surfaces. We also sell a light-duty brush for even more gentle cleaning. Think of it like a toothbrush - stiffer bristles means deeper cleaning but can also hurt your gums, so choosing the right hardness for your application is important for clean, long lasting floors!
