Abstract: A breast pump apparatus, including a vacuum pump and a variable-volume buffer volume coupled together in fluid communication, also includes a breast-receiving portion coupled to the vacuum pump and the buffer volume such that the vacuum pump is operable to generate negative pressure at the breast-receiving portion to stimulate milk expression, and the negative pressure generated at the breast-receiving portion can be controlled by controlling the buffer volume.

Abstract: The invention relates to a domestic surface treatment appliance (1), such as a vacuum cleaner, iron or lawn mower, provided with a treatment head (2) for treating a surface by wiping along or passing over said surface. The appliance (1) furthermore comprises tracking means (12) for recording wiping movements of the treatment head (2), and a user interface (15) for presenting the recorded wiping movements as strokes (S) on a display (16), enabling a user to readily spot missed surface parts. The appliance (1) may further comprise quality detection means (14), for measuring a parameter representative of the achieved quality. This quality parameter can be presented to a user by the color of the strokes (S). The invention furthermore relates to a module (10), comprising tracking means (12), a user interface (15) and possible quality detection means (14), for use with a domestic surface treatment appliance (1).
