Abstract (en)
A method and system for determining on which of a plurality of categories of flooring (130), each having a different hardness, a nozzle (111) of a vacuum cleaner (110) is positioned. Data representative of a torque load of a motor that rotates a brush in the nozzle is obtained and processed to generate a trimmed estimator of a parameter that measures variation in the data. A determination that the nozzle is positioned on the softest category of flooring is made in response to the trimmed estimator breaching a predetermined threshold.
