Not necessarily.
Low gearing means that the robot is capable of outputting more torque at its wheels. A high coefficient of friction between your robot and the carpet helps to transmit that torque to the floor, moving your robot.
If the robot is geared so that it can push really hard and your wheels don't slip on the carpet at a certain threshold, you
can draw enough current to pop breakers.
Remember that motors draw the most current at stall -- i.e., when they're exerting the most torque possible. Gearing lower gives a robot the ability to exert more force, but it doesn't do it without an expense.
Similarly, a high gearing trades torque for speed. However, highly geared robots often pop breakers, too. The reason for the popped breakers is the same in both cases. The motor reaches stall (or something over 40A) before the wheels slip.
