What exactly does Vector Aimbot mean?

A lot of fps game cheat sellers are promoting it's a vector aimbot.

Is it a different system from the conventional normal Aimbot?

I want to know the exact meaning of vector animbot.

I got no idea but I really wanna know too!

Vector aimbot refers to changing your players head rotation, ie. your pitch, yaw, and roll which is stored as a Vector. Other aimbots typically use mouse input to aim at enemies. Vector aimbot isn't necessarily better, but it always works at any sensitivity and on controller and mouse.
