What a strange design. In my vacuum this kind of brush is just "powered" by air suction. No motors, no belts etc.

The ones with belts tend to do a better job cleaning because you aren't losing all of that suction power to the brushes. And you can get a lot more torque out of a belt-driven assembly in general.

Why would I need more torque for a brush? I'm not bending steel beams there. I have my vacuum set at "minimum" power since it already sucks everything up. Maybe that's because there are no extra holes on the side for belt and stuff that leaks air left and right?

If you can't understand how torque relates to rotational forces then google can probably help. The benefit from direct drive assemblies comes from their mechanical simplicity, not from heightened performance. Not sure what your point is here besides that the most common type of vacuum cleaner is a "strange design."
