A battery-operated surface treatment apparatus having a booster function, preferably a vacuum cleaner, comprises an electric motor (10) which drives a treatment unit, such as a suction fan. Further, the apparatus comprises a battery-powered power supply unit (11) for the motor and, in addition, the apparatus is provided with a coupling device (18, 23) for the activation of the booster function by temporarily connecting a separate battery (14) in series with the batteries in the power supply unit (11). L'appareil de traitement de surfaces décrit, fonctionnant à piles et ayant une fonction de survoltage, tel que de préférence un aspirateur, comprend un moteur électrique (10), lequel entraîne une unité de traitement, constituée par exemple par une soufflante d'aspiration. L'appareil comprend en outre une unité d'alimentation à piles (11) pour le moteur et également un dispositif de couplage (18, 23) servant à actionner la fonction de survoltage par connexion temporaire d'une pile séparée (14) en série avec les piles de l'unité d'alimentation (11).
