I doubt you can reproduce the special cutters on the Samsung, though I have not seen them up close and am not sure how they work. They might not be a simple blade but some micro structure. It might be related to one of those Gillette razors with multiple blades.
To clean hair wrapped around the shaft you may find the small scissors on Swiss knives useful.
Be sure and clean hair out of the regular bearing often as damaging the bearing can cause damage to the case from friction heating. This is avoided in the D model brush with the Vorwerk bushing instead of bearing. Those brushes can be used in the older Botvac
by cutting off a flange in the case and brush guard side to make room, but they just prevent damage to the bearing, not do anything about the hair itself.
