Abstract: A surface cleaning apparatus includes an air pathway having a suction inlet. A motor is configured to generate airflow through the air pathway. One or more operating parameters of the motor may vary when the suction inlet is engaged or disengaged with a surface. A power level of the motor may be controlled based, at least on part, on changes in one or more operating parameters of the motor.

Abstract: A surface cleaning apparatus includes a supply tank, a fluid dispenser, a brushroll rotatable about an axis, a brushroll motor configured to rotate the brushroll in a forward direction about the axis and a backward direction about the axis, and a controller. The controller executes a scrub mode in which the brushroll is oscillated forward and backwards about the axis to scrub a surface to be cleaned and break up a stubborn stain on the surface.
