Do the brushes with the rubber bristles cause any marks on the floor?
No, those brushes (if you’re talking the types on carpet/floor cleaners) do not leave marks because (1) they are composed of a different type of rubber and (2) they are scrubbing with a lubricant, soapy water, which prevents them from leaving marks. Some shoes come with soles that are specifically labeled as safe for hardwood or laminated floor safe (see New Balance), though generally which soles are more likely to nto cause scuff marks than black soles. Again, they are composed differently.
