METHOD FOR DETECTING THE BACK-AND-FORTH MOVEMENT OF A VACUUM CLEANER, AND CORRESPONDING VACUUM CLEANER

The invention relates to a method for detecting the back-and-forth movement of an attachment (2) of a vacuum cleaner (1), especially a household vacuum cleaner, comprising an electromotive brush (3), and to a vacuum cleaner, especially a household vacuum cleaner. The aim of the invention is to simplify one such method and to improve one such vacuum cleaner. To this end, the motor power (I M) for driving the brush (3) is measured and compared with a reference motor power (I R-M) in order to determine the back-and-forth movement, and the vacuum cleaner is provided with a measuring device (10) which measures the motor power (IM) of the electric motor (7) driving the brush (3). A comparator (13) is used to compare the measured motor power (IM) with a reference motor power (IR-M).
