PCT No. PCT/DK92/00030 Sec. 371 Date Jul. 16, 1993 Sec. 102(e) Date Jul. 16, 1993 PCT Filed Jan. 28, 1991 PCT Pub. No. WO92/12664 PCT Pub. Date Aug. 6, 1992.To vacuum up a fluid using a vacuum cleaner, there is provided an attachment (1) to which a vacuum cleaner hose (31) is connected. The attachment comprises a separation chamber (3) in which the vacuumed up liquid is separated from the suction air through deposition on the wall surfaces (5, 6, 8, 11) of the separation chamber, with the liquid then dripping down into the collection chamber (21). The liquid is thus completely separated from the air using a common vacuum cleaner without the potential for vacuum cleaner damage. To insure that the suction through the attachment is cut off in the event that the liquid in the container reaches the vicinity of the suction channel, a valve element (18) and a float element (20) are provided which cut off the suction air and therewith the flow of liquid to the attachment when the maximum liquid level has been reached in the container. A finger operated valve can optionally cut off the suction through the attachment to regulate the vacuum. |
