Abstract: A surface treatment apparatus may include a surface cleaning head having an agitator, an agitator motor configured to cause the agitator to rotate, and a controller. The controller can be configured to determine a surface type corresponding to a surface to be cleaned and to transition the surface treatment apparatus between a first operational mode and a second operational mode based, at least in part, on the determined surface type. Determining the surface type may include measuring a plurality values corresponding to a current draw of the agitator motor over a predetermined time window at a predetermined time interval, determining an average corresponding to the measured values, comparing the average to at least a first threshold, and transitioning the surface treatment apparatus between the operational modes based, at least in part, on the comparison.
