<p>The apparatus includes an intake fitting (9), for a suction air stream, that opens out into a liquid, e.g. water, container (1). An upper housing part (2,3,,23,29) is disposed on the liquid container and has an electric motor disposed in it about which at least part of which flows a coolant air flow (P). At least one turbulence chamber (43) is provided in which the suction air stream and the coolant air flow meet one another at an angle to form a mixed air stream (P'). The mixed air stream is then expelled upwardly from the cleaning apparatus through at least one outlet in the turbulence chamber.</p> |
