I may be in the minority here, but I'll confess that it is very rare that I actually find my grooming comb and use it. If I see stringed poos, then I definitely start grooming, but honestly that is rare indeed.
I'll pet my buns and use my hands to wipe some of the loose fur chunks, but I'm hardly thorough about it, and certainly not consistent. I'm sure there are plenty of rabbits who enjoy being groomed regularly, and great for those who do that. I am just not in that camp. They've been healthy and do just fine-- even if they are a bit scruffy looking at times.
Case in point (from last night)...
