CA 2736288

A vacuum cleaner with a blockage sensor and methods of identifying an obstructed airway in a vacuum are described. The vacuum cleaner has a motor and a circuit board to provide electrical current to the motor including an amperage flow sensor to determine the electrical current draw of the motor, and a blockage determiner to sample the electrical current draw and count the number of times the sampled electrical current draw exceeds a threshold amperage within a window of time. The blockage determiner can sense a blockage within the airflow path or the beater bar, and can optionally shut down the motor prior to motor failure.
