Abstract: An automatic dishwashing composition is provided including 20 to <98.6 wt %, based on weight of the automatic dishwashing composition, of a builder; 0.2 to 20 wt %, based on weight of the automatic dishwashing composition, of a nonionic surfactant; 0.1 to <10 wt %, based on weight of the automatic dishwashing composition, of a substance of formula I wherein n is ?2 and wherein each M? is a counter ion; >0.005 to 6 wt %, based on weight of the automatic dishwashing composition, of a protease; and wherein the weight of the substance of formula I divided by the weight of the protease in the automatic dishwashing composition is <20.

Abstract: The invention discloses a control device for an integrated suction cleaner unit (1) pneumatically connected to a system of tubes (13) which open, at their ends (13A), onto couplings (11) into which the mating end (9) of a hose (8) is inserted, the latter having at its other end (8A) a handle (5) onto which are fitted the cleaning accessories. The control device for the suction cleaning unit is of the type using acoustic transmission via the tube system (13) located between the suction cleaning unit (1) and the couplings (11) pressure wave detection (19, 23 and 28) for detecting specific acoustic pressure waves and controlling the suction cleaning unit (1).
