发明名称 BOCAL DE ASPIRADOR DE PÓ, ASPIRADOR DE PÓ ROBOTIZADO, E, MÉTODO PARA LIMPAR POR SUCÇÃO UMA SUPERFÍCIE DE PISO USANDO UM BOCAL DE ASPIRADOR DE PÓ
摘要 The invention relates to a vacuum cleaner nozzle (1) bounding an inlet (2) for guiding aspirated air through the nozzle (1). The nozzle (1) comprises a rim (3, 4) along an outer end contour of the inlet (2) for contacting a floor surface area (6) when in an operating position on the floor surface (6), wherein at least a rim portion (3, 4) is movable between a 5 lowered position for contacting a floor surface (6) and a lifted position for leaving a spacing between the rim portion (3, 4) and the floor surface (6). A rim operating structure (21) is adapted for leaving the rim portion (3, 4) in the lowered position during an initial portion of a movement stroke of the nozzle over the floor surface (6) in a direction and for subsequently, during a later portion of the stroke, starting the lifting to the lifted position. This improves the aspiration of larger particles.
